Abstract:

This study demonstrated that "vocal effort" is a legitimate laryngeal perception that can be detected by many subjects who have voice disorders and by some normal control subjects. Further, subjects with voice disorders found that the degree of vocal effort in speech was greatest for voiceless obstruent consonants, followed by voiced obstruents; sonorants and nasals required the least effort. A panel of listeners, however, could not detect differences in roughness, breathiness, intonation, or overall vocal quality as the perceived vocal effort varied.

Abstract:

We have investigated the relationship between various voice qualities and several acoustic measures made from the vowel /i/ phonated by subjects with normal voices and patients with vocal disorders. Among the patients (pathological voices), five qualities were investigated: overall severity, hoarseness, breathiness, roughness, and vocal fry. Six acoustic measures were examined. With one exception, all measures were extracted from the residue signal obtained by inverse filtering the speech signal using the linear predictive coding (LPC) technique. A formal listening test was implemented to rate each pathological voice for each vocal quality. A formal listening test also rated overall excellence of the normal voices. A scale of 1–7 was used. Multiple linear regression analysis between the results of the listening test and the various acoustic measures was used with the prediction sums of squares (PRESS) as the selection criteria. Useful prediction equations of order two or less were obtained relating certain acoustic measures and the ratings of pathological voices for each of the five qualities. The two most useful parameters for predicting vocal quality were the Pitch Amplitude (PA) and the Harmonics-to-Noise Ratio (HNR). No acoustic measure could rank the normal voices.

Abstract:

In both correlational and experimental settings, studies on women’s vocal preferences have reported negative relationships between perceived attractiveness and men’s vocal pitch, emphasizing the idea of an adaptive preference. However, such consensus on vocal attractiveness has been mostly conducted with native English speakers, but a few evidence suggest that it may be culture-dependent. Moreover, other overlooked acoustic components of vocal quality, such as intonation, perceived breathiness and roughness, may influence vocal attractiveness. In this context, the present study aims to contribute to the literature by investigating vocal attractiveness in an underrepresented language (i.e., French) as well as shedding light on its relationship with understudied acoustic components of vocal quality. More specifically, we investigated the relationships between attractiveness ratings as assessed by female raters and male voice pitch, its variation, the formants’ dispersion and position, and the harmonics-to-noise and jitter ratios. Results show that women were significantly more attracted to lower vocal pitch and higher intonation patterns. However, they did not show any directional preferences for all the other acoustic features. We discuss our results in light of the adaptive functions of vocal preferences in a mate choice context.

Abstract:

Background Vocal cord sequelae and postoperative hoarseness during general anesthesia are a significant source of morbidity for patients and a source of liability for anesthesiologists. Several risk factors leading to laryngeal injury have been identified in the past. However, whether the quality of tracheal intubation affects their incidence or severity is still unclear. Methods Eighty patients were randomized in two groups (n = 40 for each) to receive a propofol-fentanyl induction regimen with or without atracurium. Intubation conditions were evaluated with the Copenhagen Score; postoperative hoarseness was assessed at 24, 48, and 72 h by a standardized interview; and vocal cords were examined by stroboscopy before and 24 and 72 h after surgery. If postoperative hoarseness or vocal cord sequelae persisted, follow-up examination was performed until complete restitution. Results Without atracurium, postoperative hoarseness occurred more often (16 vs. 6 patients; P = 0.02). The number of days with postoperative hoarseness was higher when atracurium was omitted (25 vs. 6 patients; P < 0.001). Similar findings were observed for vocal cord sequelae (incidence of vocal cord sequelae: 15 vs. 3 patients, respectively, P = 0.002; days with vocal cord sequelae: 50 vs. 5 patients, respectively, P < 0.001). Excellent intubating conditions were less frequently associated with postoperative hoarseness compared to good or poor conditions (11, 29, and 57% of patients, respectively; excellent vs. poor: P = 0.008). Similar findings were observed for vocal cord sequelae (11, 22, and 50% of patients, respectively; excellent vs. poor: P = 0.02). Conclusions The quality of tracheal intubation contributes to laryngeal morbidity, and excellent conditions are less frequently associated with postoperative hoarseness and vocal cord sequelae. Adding atracurium to a propofol-fentanyl induction regimen significantly improved the quality of tracheal intubation and decreased postoperative hoarseness and vocal cord sequelae.

Abstract:

Purpose Vocal fry is prevalent in everyday speech. However, whether the use of vocal fry is detrimental to voice production is unclear. This preliminary study assessed the effects of using continuous vocal fry on voice production measures and listener ratings. Method Ten healthy individuals (equal male and female, mean age = 22.4 years) completed 2 counterbalanced sessions. In each session, participants read in continuous vocal fry or habitual voice quality for 30 min at a comfortable intensity. Continuous vocal fry was simulated. Phonation threshold pressure (PTP 10 and PTP 20 ), cepstral peak prominence, and vocal effort ratings were obtained before and after the production of each voice quality. Next, 10 inexperienced listeners (equal male and female, mean age = 24.1 years) used visual analog scales to rate paired samples of continuous vocal fry and habitual voice quality for naturalness, employability, and amount of listener concentration. Results PTP 10 and vocal effort ratings increased after 30 min of continuous vocal fry. Inexperienced listeners rated continuous vocal fry more negatively than the habitual voice quality. Conclusions Thirty minutes of simulated, continuous vocal fry worsened some voice measures when compared with a habitual voice quality. Samples of continuous vocal fry were rated as significantly less employable, less natural, and requiring greater listener concentration as compared with samples of habitual voice quality. Future studies should include habitual users of vocal fry to investigate speech stimulability and adaptation with cueing to further understand pathogenesis of vocal fry.

Abstract:

The purpose of this study was to evaluate the effectiveness of several acoustic measures in predicting breathiness ratings. Recordings were made of eight normal men and seven normal women producing normally phonated, moderately breathy, and very breathy sustained vowels. Twenty listeners rated the degree of breathiness using a direct magnitude estimation procedure. Acoustic measures were made of: (a) signal periodicity, (b) first harmonic amplitude, and (c) spectral tilt. Periodicity measures provided the most accurate predictions of perceived breathiness, accounting for approximately 80% of the variance in breathiness ratings. The relative amplitude of the first harmonic correlated moderately with breathiness ratings, and two measures of spectral tilt correlated weakly with perceived breathiness.

Abstract:

Purpose The human voice is an exceptionally versatile instrument that is capable of complex communicative and emotive behaviors. Typically, these behaviors are sufficient for daily communication activities; however, elite vocal athletes have higher vocal demands and arguably enhanced vocal capabilities. The current definition of a voice disorder is a change in quality, pitch, and loudness of the voice that draws attention to the speaker. In this article, we suggest that this definition does not provide an adequate description of voice problems of elite vocal athletes. Conclusion As a result, the current clinical system of evaluation and intervention may fail to meet the needs of the exceptional voice when even a subtle decline in vocal quality may affect performance. Under the current definition of a voice disorder, these vocal changes may not qualify for vocal rehabilitation supported by 3rd-party payers. To address this issue, we offer a definition of the exceptional voice, propose expansion of the current voice production continuum to include high-level vocal performers, and provide recommendations for the rehabilitation and habilitation of the exceptional voice.

Abstract:

The song is a means of entertainment most often heard by humans where in the song consists of music and vocals. Good quality music and vocal singers will make a song more pleasant to hear. To make the song sound tunable and in accordance with the rhythm can be done by adjusting the vocals according to the tone of the song. From this we know that measuring sound frequencies needs to be done to determine whether a frequency or period is loud, it can also be used as a tool in vocal training, one of them for vocal tuning applications to find the harmonious sound of the sound. Moreover, it can be used as a learning need in Sound Frequency Processing. Where one of the parts to create a vocal tuning application can be through the Real-time spectrogram program. This RTS uses Pyaudio as sound recording, uses the Python 3.6 programming language and uses the Fast Fourier Transform method which will help when making real-time spectrogram and pitch detection programs. The test results obtained 75% accuracy in real-time pitch detection programs.

Abstract:

Purpose The purpose of this study was to determine the vocal fold structural and vibratory symmetries that are important to vocal function and voice quality in a simulated paramedian vocal fold paralysis. Method A computational kinematic speech production model was used to simulate an exemplar “voice” on the basis of asymmetric settings of parameters controlling glottal configuration. These parameters were then altered individually to determine their effect on maximum flow declination rate, spectral slope, cepstral peak prominence, harmonics-to-noise ratio, and perceived voice quality. Results Asymmetry of each of the 5 vocal fold parameters influenced vocal function and voice quality; measured change was greatest for adduction and bulging. Increasing the symmetry of all parameters improved voice, and the best voice occurred with overcorrection of adduction, followed by bulging, nodal point ratio, starting phase, and amplitude of vibration. Conclusions Although vocal process adduction and edge bulging asymmetries are most influential in voice quality for simulated vocal fold motion impairment, amplitude of vibration and starting phase asymmetries are also perceptually important. These findings are consistent with the current surgical approach to vocal fold motion impairment, where goals include medializing the vocal process and straightening concave edges. The results also explain many of the residual postoperative voice limitations.

Abstract:

Singing voice disorders are an important segment of vocal pathology, targeting a niche of professional and amateur singers of all musical genres. The aim of this study is to evaluate the effectiveness of using the principles of vocal hygiene and the eclectic vocal therapy model by combining three resonant vocal techniques: humming, the method of disguised yawning and the chewing technique, in the corrective-recuperative vocal therapy program. The positive effects of the vocal therapy used in all five case studies were observed. If the initial assessment relates to altered vocal parameters, pain in the laryngeal muscles and a negative influence of vocal problems on quality of life, the final assessment found normalization of vocal parameters, decreased pain and improved the quality of life.

Abstract:

Vocal warm-up has garnered much research attention these recent years. This study compared the short-term effects of straw phonation (SP) with a traditional vocal warm-up (TVW) on the vocal quality of untrained female singers. It also determined the effect of exercise type on the vocal economy and skill acquisition. Vocal quality was measured using voice range profile (VRP), multi-parametric index, acoustic, and aerodynamic parameters. Eighty participants were randomly recruited and divided into two equal groups to perform vocal warm-ups at a frequency of two 10-minute sessions per day for three weeks. Voice data were collected using Praat and Vocalgrama software, while the statistical results were analysed using Statistical Product and Service Solution (SPSS). As a result, some parameters, i.e., fundamental frequency maximum (F0-max), maximum intensity (max Int) and area of VRP, fundamental frequency (F0), jitter, shimmer, harmonics-to-noise ratio (HNR), and dysphonia severity index (DSI), projected significant changes after three weeks of warming up exercise in TVW group. In the SP group, the participants experienced significant changes in max Int and area of VRP only. Both groups did not exert significant changes to min Int, which indirectly measures phonation threshold pressure (PTP), signifying no improvement for the vocal economy. Participants from the TVW group benefitted the most from vocal warm-ups due to notable improvement in vocal quality, technical singing skills (i.e., skill acquisition), and vocal efficiency. Meanwhile, the SP group only benefitted in terms of enhanced vocal efficiency.

Abstract:

Purpose: To measure the voice-related quality of life in children/adolescents with vocal complaints through the validation of the Brazilian Pediatric Voice-Related Quality-of-Life survey - VR-QOL-P (Qualidade de Vida em Voz Pediátrico - QVV-P), to verify whether the presence of vocal complaints interfere with the quality of life of children/adolescents, and to determine the relationship between the vocal assessment carried out by parents and the VR-QOL-P scores. Methods: The participants included 246 parents of children/adolescents of both sexes, aged between 2 years and 18 years (divided into preschoolers, schoolers and adolescents), with and without vocal complaints. All participants signed the informed consent form. Translation, linguistic and cultural adaptation, assessment of cultural equivalence, implementation of the protocol in its final version, voice assessment by parents, demographic and clinical descriptive statistical analysis of the population, individual analysis of the items, verification of psychometric measures of validation, reliability, reproducibility and responsiveness of the instrument to treatment, were carried out. Results: Low scores, especially in the physical domain, were found in subjects with vocal complaints. Among those, adolescents suffered the greatest impact. The social-emotional domain was not sensitive in preschoolers. There was a correlation among the overall, social-emotional and physical scores, and the vocal assessment performed by parents. The VR-QOL-P was reliable, reproducible and responsive to voice problems. Conclusion: Voice change interferes with the quality of life of children/adolescents, and there is a relationship between the assessment of voice quality and VR-QOL-P scores - the older the individual, the worse the quality of life in aspects related to voice, especially in the physical domain, and the better the vocal quality, as perceived by the parents.

ABSTRACT Objective: to assess the effects of surface hydration on vocal quality according to teachers’ self-perception. Methods: an examiner-blinded pre-test and post-test intervention study carried out with a single group of 27 teachers. Sociodemographic characteristics and work questionnaire, Screening Index for Voice Disorder, Vocal Severity Rating Scale, Expected Effects Pre-intervention, Perceived Effects Post-intervention and Post-intervention Perception instruments, were applied. The intervention lasted 4 weeks and consisted of 5 minutes of nebulization with saline solution (sodium chloride 0.9%), after 10 minutes of mouth dehydration, prior to teaching. Results: screening Index for Voice Disorder scores demonstrated a statistically significant reduction (p=0.001). Frequency of voice disorders in the Vocal Severity Rating Scale was reduced without a statistical significance (p= 0.172). Expected Effects, Pre-intervention, and Perceived Effects, Post-intervention, showed improvement in vocal quality (40.7%), vocal comfort (40.7%) and vocal folds hydration (37%). Post-intervention perception form showed moderate improvement of the symptoms (59.3%), cleared voice (55.6%) and ease speaking (48.1%) as well as intense belief in the intervention (74.1%) and intense compliance to the intervention (74.1%). Conclusion: surface hydration with saline solution promoted self-perceived improvement in vocal quality.

Abstract:

PURPOSE: To compare the vocal self-perception and vocal complaints reported by two groups of students of the pedagogy course (freshmen and graduates); to relate the vocal self-perception to the vocal complaints for these groups; and to compare the voice quality of the students from these groups through perceptual auditory assessment and acoustic analysis. METHODS: Initially, 89 students from the pedagogy course answered a questionnaire about self-perceived voice quality and vocal complaints. In a second phase, auditory-perceptual evaluation and acoustic analyses of 48 participants were made through voice recordings of sustained vowel emission and poem reading. RESULTS: The most reported vocal complaints were fatigue while using the voice, sore throat, effort to speak, irritation or burning in the throat, hoarseness, tightness in the neck, and variations of voice throughout the day. There was a higher occurrence of complaints from graduates than from freshmen, with significant differences for four of the nine complaints. It was also possible to observe the relationship between vocal self-perception and complaints reported by these students. No significant differences were observed in the results of auditory-perceptual evaluation; however, some graduates had their voices evaluated with higher severity of deviation of normalcy. During acoustic analysis no difference was observed between groups. CONCLUSION: The increase in vocal demand by the graduates may have caused the greatest number and diversity of vocal complaints, and several of them are related to the self-assessment of voice quality. The auditory-perceptual evaluation and acoustic analysis showed no deviations in their voice.

Abstract:

Purpose Many children with cerebral palsy (CP) are described as having altered vocal quality. The current study utilizes psychoacoustic measures, namely, low-amplitude (H1*–H2*) and high-amplitude (H1*–A2*) spectral tilt and cepstral peak prominence (CPP), to identify the vocal fold articulation characteristics in this population. Method Eight children with CP and eight typically developing (TD) peers produced vowel singletons [i, ɑ, u] and a story retell task with the same vowels in the words “beets, Bobby, boots.” H1*–H2*, H1*–A2*, and CPP were extracted from each vowel. Results were analyzed with mixed linear models to identify the effect of Group (CP, TD), Task (vowel singleton, story retell), and Vowel [i, ɑ, u] on the dependent variables. Results Children with CP have lower spectral tilt values (H1*–H2* and H1*–A2*) and lower CPP values than their TD peers. For both groups, vowel singletons were associated with lower CPP values as compared to story retell. Finally, the vowel [ɑ] was associated with higher spectral tilt and higher CPP values as compared to [i, u]. Conclusions Children with CP have more constricted and creaky vocal quality due to lower spectral tilt and greater noise. Unlike adults, children demonstrate poorer vocal fold articulation when producing vowel singletons as compared to story retell. Finally, low vowels like [ɑ] seem to be produced with less constriction and noise as compared to high vowels.

Abstract:

PURPOSE: To verify the relationship between the clinician's vocal evaluation and vocal self-assessment and voice-related quality of life. METHODS: Participants were 96 individuals: 48 with vocal complaints and voice deviation (VCG), mean age of 51 years, with diagnosis and indication of voice therapy; and 48 with no vocal complaints and healthy voices (NVCG), mean age of 46 years. All participants answered the Voice-Related Quality of Life (V-RQOL) questionnaire, performed a vocal self-assessment and were submitted to auditory-perceptual analysis of voice. RESULTS: Mean V-RQOL scores were different between groups for all domains. Self-assessment results also showed differences between groups, which was not the case in the auditory-perceptual analysis of sustained vowel and connected speech, showing that the patient's perception was worse than the clinician's. There was correlation between the V-RQOL domains (Socio-emotional and Physical: 76.8%; Socio-emotional and Total: 90.8%; Physical and Total: 95.8%), as well as between the Socio-emotional (-52.9%), Physical (-43.1%) and Total (-52.2%) domains and the self-assessment. However, no correlation was found between auditory-perceptual analysis and self-assessment measures, except for a weak correlation between vocal self-assessment and auditory-perceptual analysis of the sustained vowel (33.3%). CONCLUSION: The clinician's perception does correspond to the individual's self-perception of his/her vocal quality and the impact of a voice deviation on his/her quality of life, but not directly. The individual's perception about his/her vocal quality and voice-related quality of life complements the clinician's perception regarding the overall degree of the voice deviation.

Abstract:

During pregnancy, voice quality disorders may occur in form of: edema, dryness, nervousness. The aim of the study is subjective and objective evaluation of voice quality in pregnant women. The study included 20 women in the third trimester of pregnancy, age of 20-31 diagnosed at the Department of Clinical Phonoaudiology and Logopedics, Medical University of Bialystok. Subjective assessment has been based on the GRBAS scale. Objective assessment of the vocal organ used the HSDI technique (High Speed Digital Imaging). In the laryngeal visualization, high-speed camera (HS) using rigid endoscope with 90 ° optics has been used. Vibration of vocal folds has been recorded during phonation of vowel "e" at 4000 frames / sec. The glottal closure (GTs), symmetry, regularity and synchronization of vocal folds vibration have been assessed. In estimating the degree of glottal insufficiency, kymography of the larynx has been performed by analyzing the value of Open Quotient (OQ). Objective acoustic evaluation of voice has been also conducted using DiagnoScope Specjalista Program. Hoarseness has been observed in 15 pregnant women, whereas voice fatigability in 20 patients. Using HSDI, the edema of vocal folds in part of the group has been observed. Decreased MPT has been found in all examined women in the third trimester of pregnancy. Hoarseness and fatigability of voice are the most frequent subjective symptoms of voice organ in the third trimester of pregnancy. Decreased MPT is recorded objectively, as well as edema and insufficiency of vocal folds using HSDI technique.

Abstract:

This study investigated changes in voice quality after thyroplasty type I in eight adults with unilateral vocal fold paralysis. A silicone rubber implant was inserted through a window in the thyroid ala and placed between the inner and outer perichondrium to externally medialize the abducted vocal fold. Measures of fundamental frequency (vocal pitch), pitch range, maximum phonation time, s/z ratio, pitch perturbation (vocal jitter), and amplitude perturbation (vocal shimmer) were made 1 to 2 weeks preoperatively and 1 month postoperatively. Postoperative voice quality was characterized by an improved pitch range, phonation time, s/z ratio, and pitch and amplitude perturbation. No change was noted in fundamental frequency. Changes in postoperative voice quality were unrelated to the subjects' preoperative age, sex, etiology, and duration of the paralysis.

Abstract:

The quality evaluation of vocal music teaching for music majors is of great significance to music education. Based on the theory of multiple intelligences, this paper constructs a model for evaluating the quality of vocal music teaching for music majors and introduces the theory of multiple intelligences into the operation form, design requirements, and recommended lesson examples of music teaching unit design. The experimental data and questionnaire data collected by the model verify that this operation is beneficial to the improvement of students’ music listening scores, vocal music comprehension scores, and total scores and solves the quantitative problem of vocal music teaching quality evaluation. In the simulation process, the engineering testing and analysis method uses the correlation rate and correlation strength as the analysis indicators, comparing the platforms for the quality evaluation of vocal music teaching in music majors and the corresponding quality evaluation data preprocessing process. The experimental results show that the algorithm performance evaluation is carried out based on the three aspects of quality evaluation association rules, algorithm running time, and algorithm memory consumption. The multiple intelligence algorithm is applied to vocal music teaching analysis of association rules for quality evaluation: when 4000 tasks call for 20–40 virtual resources, the total time spent is reduced by 61.7%, which has a significant positive effect on the knowledge expansion and ability improvement of music majors.

Abstract:

To cultivate students’ artistic quality, enhance their vocal music quality, and prepare them to make great contributions to the innovation and development of my country’s vocal music art is the main goal of opening vocal music performance major in colleges and universities. With the advancement of technology and the demands of talent development, the vocal music teaching methodology for the vocal music performance major in colleges and universities must be continuously enhanced. Otherwise, there will be an issue of disconnect between teaching style and talent development, which will harm both the development of high-quality vocal music talents and the innovation and growth of vocal music performance majors in colleges and universities. The vocal music performance major at colleges and universities should actively support the reform and innovation of the vocal music teaching mode in order to extend students’ knowledge, develop their all-around ability, and provide a strong foundation for vocal music performance, to develop students’ all-encompassing musical abilities. This research suggests a design strategy for the monitoring and model optimization of the teaching environment for vocal performance majors from the standpoint of core literacy. To increase the efficiency and objectivity of course instruction, cluster analysis aids students in categorising and searching for vocal music performance main repertoire as well as using collaborative filtering recommendations to locate their own vocal music performance. The simulation test analysis is completed lastly. The method has a certain accuracy, which is 7.59% higher than the conventional algorithm, according to the simulation findings. In addition to significantly increasing student interest in studying vocal music performance courses, we further reform and innovation of the teaching method for these courses at colleges and universities can also strengthen students’ understanding of various repertoire styles and significantly enhance their musical literacy.

Abstract:

ABSTRACTThe purpose of the present study was to determine whether the VERBAL component of babytalk affected the vocal quality of infants. Two groups of 20 0;3 infants experienced either conversational turn taking or random responsiveness of an adult. Adult responsiveness consisted of a smile, light touch to the abdomen, and a NONVERBAL ‘tsk, tsk, tsk’ sound (instead of speech). All infant vocalizations were counted and then coded as ‘syllabic’ or ‘vocalic’ sounds. The results of the study demonstrated that TURN TAKING facilitated a speak-listen pattern of vocalizing by the infant, but in the absence of the VERBAL component of the adult's response, turn taking had no special facilitative effect on syllabic sounds. It was concluded that what adults say to 3-month-old infants influences what infants ‘say’ in return. Possible mechanisms underlying the infant's vocal response to verbal input were reviewed. It was suggested that the more mature sounds (syllabic) may proportionally increase as a result of the combined effects of turn-taking and verbal stimulation on the motor control of respiration and phonation.

Abstract:

AbstractObjectives:To review the clinical signs of vocal fold paresis on laryngeal videostroboscopy, to quantify its impact on patients’ quality of life and to confirm the benefit of laryngeal electromyography in its diagnosis.Methods:Twenty-nine vocal fold paresis patients were referred for laryngeal electromyography. Voice Handicap Index 10 results were compared to 43 patients diagnosed with vocal fold paralysis. Laryngeal videostroboscopy analysis was conducted to determine side of paresis.Results:Blinded laryngeal electromyography confirmed vocal fold paresis in 92.6 per cent of cases, with vocal fold lag being the most common diagnostic sign. The laryngology team accurately predicted side of paresis in 76 per cent of cases. Total Voice Handicap Index 10 responses were not significantly different between vocal fold paralysis and vocal fold paresis groups (26.08 ± 0.21 and 22.93 ± 0.17, respectively).Conclusion:Vocal fold paresis has a significant impact on quality of life. This study shows that laryngeal electromyography is an important diagnostic tool. Patients with persisting dysphonia and apparently normal vocal fold movement, who fail to respond to appropriate speech therapy, should be investigated for a diagnosis of vocal fold paresis.

Abstract:

Vocal loading tasks are often used to investigate the relationship between voice use and vocal fatigue in laboratory settings. The present study investigated the concept of a novel quantitative dose-based vocal loading task for vocal fatigue evaluation. Ten female subjects participated in the study. Voice use was monitored and quantified using an online vocal distance dose calculator during six consecutive 30-min long sessions. Voice quality was evaluated subjectively using the CAPE-V and SAVRa before, between, and after each vocal loading task session. Fatigue-indicative symptoms, such as cough, swallowing, and voice clearance, were recorded. Statistical analysis of the results showed that the overall severity, the roughness, and the strain ratings obtained from CAPE-V obeyed similar trends as the three ratings from the SAVRa. These metrics increased over the first two thirds of the sessions to reach a maximum, and then decreased slightly near the session end. Quantitative metrics obtained from surface neck accelerometer signals were found to obey similar trends. The results consistently showed that an initial adjustment of voice quality was followed by vocal saturation, supporting the effectiveness of the proposed loading task.

Abstract:

Treatment of symptomatic unilateral vocal cord paralysis is most frequently surgical. Medialization of the vocal cord using Teflon injection has proved effective; however, studies have shown this technique to produce stiffness of the vocal fold with loss of the “mucosal wave” and concomitantly poor vocal function. As well, overcorrection may occur and is not reversible. Isshiki type 1 medialization thyroplasty has been shown to produce a substantial improvement In vocal quality, as well as preserve the mucosal wave. A number of problems encountered during the performance of isshiki type 1 thyroplasty has led us to modify the original technique. We have developed a new implant that allows for precise, easily adjustable control of vocal cord medialization. To evaluate the degree of vocal cord medialization afforded by this implant, larynges of fresh male and female cadavers were used as an experimental model. In both larynges, vocal cord medialization was shown to occur in a predictable fashion for the anterior, middle, and posterior segments, as well as In the functionally Important inter-arytenoid region. We believe the use of this implant in medialization thyroplasty will allow precise, atraumatic medialization of the paralyzed vocal cord. This greater control over positioning and ease of adjustment should contribute to enhanced vocal quality.
