Abstract:
Most studies investigating neural representations of species-specific vocalizations in non-human primates and other species have involved studying neural responses to vocalization tokens. One limitation of such approaches is the difficulty in determining which acoustical features of vocalizations evoke neural responses. Traditionally used filtering techniques are often inadequate in manipulating features of complex vocalizations. Furthermore, the use of vocalization tokens cannot fully account for intrinsic stochastic variations of vocalizations that are crucial in understanding the neural codes for categorizing and discriminating vocalizations differing along multiple feature dimensions. In this work, we have taken a rigorous and novel approach to the study of species-specific vocalization processing by creating parametric “virtual vocalization” models of major call types produced by the common marmoset ( Callithrix jacchus). The main findings are as follows. 1) Acoustical parameters were measured from a database of the four major call types of the common marmoset. This database was obtained from eight different individuals, and for each individual, we typically obtained hundreds of samples of each major call type. 2) These feature measurements were employed to parameterize models defining representative virtual vocalizations of each call type for each of the eight animals as well as an overall species-representative virtual vocalization averaged across individuals for each call type. 3) Using the same feature-measurement that was applied to the vocalization samples, we measured acoustical features of the virtual vocalizations, including features not explicitly modeled and found the virtual vocalizations to be statistically representative of the callers and call types. 4) The accuracy of the virtual vocalizations was further confirmed by comparing neural responses to real and synthetic virtual vocalizations recorded from awake marmoset auditory cortex. We found a strong agreement between the responses to token vocalizations and their synthetic counterparts. 5) We demonstrated how these virtual vocalization stimuli could be employed to precisely and quantitatively define the notion of vocalization “selectivity” by using stimuli with parameter values both within and outside the naturally occurring ranges. We also showed the potential of the virtual vocalization stimuli in studying issues related to vocalization categorizations by morphing between different call types and individual callers.

Abstract:
Every tarsier species performs different vocalization behaviour. Cephalopachus bancanus as one of the tarsier species listed as vulnerable in the IUCN red list has limited and different information about their vocalization. This research was designed to explore the species vocalization in the vicinity of Petaling Village, District of Bangka, Bangka Island, Indonesia. Tarsier vocalization inside temporary enclosures was recorded using a handy recorder and analysed using bioacoustics software Audacity 2.3.3 and Raven Pro 1.6.1. We described seven vocalization types with different functions and spectrogram patterns. One type of vocalization, squeak, is produced only by the infant. Two types of vocalizations (whistle and cheeps) were produced by the infant and adult, and four vocalization types were performed by adults. Those types of vocalizations can be heard within human hearing. Some types of vocalizations have peak frequencies at the ultrasonic level, i.e.: agonistic scream, alarm call, distress call, and hysteresis.

Abstract:
Objectives: This study investigated the relationship of phonological characteristics between early vocalizations at 6-8 months, 12-14 months, and words at 18-20 months. Additionally, we aimed to identify which phonological characteristics of early vocalization can predict speech and language development at 18-20 months.Methods: Vocalizations were collected using Language ENvironmental Analysis (LENA) from 14 children at 6-8, 12-14, and 18-20 months. Vocalizations were classified as precanonical or canonical vocalization. Words were separated from the entire vocalizations at 18-20 months. Consonant inventories and phonological structures were analyzed in early vocalizations and words. Multiple regression analysis was performed to investigate whether the rate of canonical vocalizations, the number of consonant inventories, and the number of phonological structures in early vocalization are predictive of the number of consonant inventories and the number of different words at 18-20 months.Results: Consonant inventories and phonological structures in words at 18-20 months consisted of inventories which had been produced in early vocalization at 6-8 months and 12-14 months. The results showed that the ratio of canonical vocalizations at 6-8 months predicted the number of consonant inventories and the number of different words. The number of consonant inventories at 12-14 months also predicted the number of consonant inventories in words at 18-20 months.Conclusion: This study confirmed that the phonological development of early vocalization is closely related to later speech-language development, and the speech-language evaluation based on the phonological characteristics of early vocalization can provide a basis for early diagnosis and intervention in infants and toddlers.

Abstract:
Little is known about sensory-motor interaction in the auditory cortex of primates at the level of single neurons and its role in supporting vocal communication. The present study investigated single-unit activities in the auditory cortex of a vocal primate, the common marmoset ( Callithrix jacchus), during self-initiated vocalizations. We found that 1) self-initiated vocalizations resulted in suppression of neural discharges in a majority of auditory cortical neurons. The vocalization-induced inhibition suppressed both spontaneous and stimulus-driven discharges. Suppressed units responded poorly to external acoustic stimuli during vocalization. 2) Vocalization-induced suppression began several hundred milliseconds prior to the onset of vocalization. 3) The suppression of cortical discharges reduced neural firings to below the rates expected from a unit's rate-level function, adjusted for known subcortical attenuation, and therefore was likely not entirely caused by subcortical attenuation mechanisms. 4) A smaller population of auditory cortical neurons showed increased discharges during self-initiated vocalizations. This vocalization-related excitation began after the onset of vocalization and is likely the result of acoustic feedback. Units showing this excitation responded nearly normally to external stimuli during vocalization. Based on these findings, we propose that the suppression of auditory cortical neurons, possibly originating from cortical vocal production centers, acts to increase the dynamic range of cortical responses to vocalization feedback for self monitoring. The excitatory responses, on the other hand, likely play a role in maintaining hearing sensitivity to the external acoustic environment during vocalization.

Abstract:
Auditory-vocal interaction, the modulation of auditory sensory responses during vocal production, is an important but poorly understood neurophysiological phenomenon in nonhuman primates. This sensory-motor processing has important behavioral implications for self-monitoring during vocal production as well as feedback-mediated vocal control for both animals and humans. Previous studies in marmosets have shown that a large portion of neurons in the auditory cortex are suppressed during self-produced vocalization but have primarily focused on a single type of isolation vocalization. The present study expands previous analyses to compare auditory-vocal interaction of cortical responses between different types of vocalizations. We recorded neurons from the auditory cortex of unrestrained marmoset monkeys with implanted electrode arrays and showed that auditory-vocal interactions generalize across vocalization types. We found the following: 1) Vocal suppression and excitation are a general phenomenon, occurring for all four major vocalization types. 2) Within individual neurons, suppression was the more general response, occurring for multiple vocalization types, while excitation tended to be more specific to a single vocalization type. 3) A subset of neurons changed their responses between different types of vocalization, most often from strong suppression or excitation for one vocalization to unresponsive for another, and only rarely from suppression to excitation. 4) Differences in neural responses between vocalization types were weakly correlated with passive response properties, measured by playbacks of acoustic stimuli including recorded vocalizations. These results indicate that vocalization-induced modulation of the auditory cortex is a general phenomenon applicable to all vocalization types, but variations within individual neurons suggest possible vocalization-specific coding.

Abstract:
Abstract The main argument for the unreliability of the Tiberian vocalization in Targum manuscripts of western origin is the inconsistency with which the vocalization signs are applied. The author argues that in certain manuscripts this inconsistency is the result of a non-Tiberian vocalization system which uses the Tiberian vocalization signs, the so-called Palestino-Tiberian vocalization system. A passage from an Ashkenazic Targumic manuscript with Palestino-Tiberian vocalization is examined and its 'inconsistencies' are explained in light of similar vocalizations in manuscripts of Rabbinic Hebrew. The author suggests that manuscripts with Palestino-Tiberian vocalization may reflect the pronunciation tradition of Palestinian Aramaic of Late Antiquity.

Abstract:
Objectives: This study aimed to examine the temporal characteristics of infant vocalizations during interactions with adults in natural home environments.Methods: One day LENA (Language ENvironment Analysis) recordings were collected from 20 infants aged 6 and 12 months. The collected data were analyzed by selecting 20 5-mintue intervals in the order of highest CTCs (conversational turn counts). In the analysis unit of turn-taking, interactions in which the infant responded within 0.05 seconds to 3 seconds after the adult spoke directly to the infant were regarded as one analysis unit. The temporal characteristics of infant vocalization during interactions with adults were examined through infants’ Vocalization response ratio. The temporal characteristics of infant vocalization in interactions with adults were examined by the after adults’ infant-directed speech (IDS), latency of vocalization response and overlapping vocalization ratio.Results: Infants’ Vocalization response ratio following IDS in adults did not differ significantly between the two age groups. Infants’ Vocalization response latencies increased significantly with age from 6 to 12 months. Overlapping vocalization ratio showed a significant decrease with increasing age.Conclusion: This study supports that as infants grow, they acquire temporal turn-taking skills. It also suggests that the temporal characteristics of infant vocalizations during interactions with adults may be a useful to predict infants’ language development.

Abstract:
The structure of the thoracic and abdominal walls of Pteronotus parnellii (Microchiroptera: Mormoopidae) was described with respect to their function in respiration and vocalization. We monitored electromyographic activity of respiratory and flight muscles in relation to echolocative vocalization. In flight, signals were telemetered with a small FM transmitter modified to summate the low-frequency myopotentials with biosonar signals from a ceramic-crystal microphone. Recordings were also made from the same bats confined to a small cage. Vocalizations were used as the parameter by which all muscle activities were correlated. A discrete burst of activity in the lateral abdominal wall muscles accompanied each vocalization. Diaphragmatic myopotentials occurred between groups of calls and did not coincide with activity of the abdominal wall or with vocalizations. Flight muscles were not active in resting bats. During flight, vocalizations and the abdominal muscle activity that accompanied them coincided with myopotentials of the pectoralis and serratus ventralis muscles. We propose that contractions of the lateral abdominal wall provide the primary power for the production of intense biosonar vocalization in flying and in stationary bats. In flight, synchronization of vocalization with activity of the pectoralis and serratus ventralis jointly contribute to the pressurization of the thoraco-abdominal cavity. This utilization of pressure that is normally generated in flight facilitates respiration and allows for the production of intense vocalizations with little additional energetic expenditure.

Abstract:
This study tested the relationship between prelinguistic vocalization and expressive vocabulary 1 year later in young children with mild to moderate developmental delays. Three vocalization variables were tested: rate of all vocalization, rate of vocalizations with consonants, and rate of vocalizations used interactively. The 58 toddlers in the study were 17–34 months old, not sensory impaired, and had Bayley Mental Development Indices (Bayley, 1969; Bayley, 1993) from 35–85. In addition, the children had fewer than 3 words in their expressive vocabularies and during classroom observation each showed at least one instance of intentional prelinguistic communication before testing. Selected sections of the Communication and Symbolic Behavior Scales procedures (CSBS; Wetherby & Prizant, 1993) were administered at the beginning and at the end of the study. The vocal measures were obtained in the initial CSBS session. One measure of expressive vocabulary was obtained in the CSBS session at the end of the study. In addition, expressive vocabulary was measured in a nonstructured play session at the end of the study. We predicted that rate of vocalization, rate of vocalizations with consonants, and rate of vocalizations used interactively would all be positively related to later expressive vocabulary. The results confirmed the predictions.

Abstract:
The aim of the study was to assess the impact of the duration of the mating season and the time of day on the parameters of the vocalization pheasants (duration of vocalization, frequency of the sound wave, intervals between vocalizations). In the study, pheasant vocalization recorded in the morning (600–800) and in the afternoon (1600–1800) between April and June 2020 was analyzed. In total, the research material consisted of 258 separate vocalizations. After recognition of the individual songs of each bird, frequency-time indicators were collected from the samples to perform statistical analysis of the recorded sounds. The duration of the first syllable [s], the duration of the second syllable [s], the duration of the pause between the syllables [s], the intervals between successive vocalizations [min], and the peak frequency of the syllables I and II [Hz] were specified for each song. The duration of the syllables and the pauses between the syllables and vocalizations were determined through evaluation of spectrograms. The peak amplitude frequencies of the syllables were determined via time-frequency STFT analysis. Statistically significant differences in the distributions of the values of all variables between the analyzed months were demonstrated. The longest duration of total vocalization and the shortest time between vocalizations were recorded in May. Therefore, this month is characterized by the highest frequency and longest duration of vocalization, which is related to the peak of the reproductive period. The time of day was found to exert a significant effect on all variables except the duration of syllable II. The duration of vocalization was significantly shorter in the morning, which indicates that the cooks are more active at this time of day in the study area. The highest peak amplitude frequencies of both syllables were recorded in April, but they decreased in the subsequent months of observation. The time of day was also shown to have an impact on the peak amplitude frequencies, which had the highest values in the morning.

Abstract:
Vocalization behavior of captive loggerhead shrikes was studied at the Avian Science and Conservation Centre of McGill University. In the first stage, calls of two pairs kept in indoor cages were individually recorded not only to catalogue these calls spectrographically and quantitatively but also to use them in identifying the birds sexually. Males vocalized 21 call figures for 16.50% of the observation time and females, 8 call figures for 2.64% of the observation time. Males contiguously delivered 1 to 11 bouts with a mean of 7.25 min for a rate of 6.06 bouts/h; females delivered 1 to 9 bouts with a mean of 4.07 min for a rate of 1.27 bouts/h. Males not only vocalized at a higher rate and longer than females, but also demonstrated trill calls which the females did not do. In the second stage, five pairs were paired in large outdoor breeding pens. Their calls were recorded and current visual displays observed in an effort to understand calls related to breeding behaviors. Two new calls figures vocalized by males as well as 2 call figures by young shrikes were recorded. Each male demonstrated distinctive calls that differed from those of other males during nest-site selection, nest building and copulation, but similar calls during food offering, aggressive and alarm behavior. Despite the call differences, all males performed similar visual displays during the above activities. Conversely, breeding females gave no calls, other than harsh calls during food offering, food begging, aggressive and alarm behaviors.

Abstract:
The bottlenose dolphin Tursiops truncatus is an extremely well-studied species. We have an extensive knowledge of certain aspects of their vocal behaviour, particularly from captive contexts. Bottlenose dolphins produce a rich tapestry of vocalisations, however, which have historically received minimal attention. Resident groups of bottlenose dolphins frequent the waterways of Fiordland in southwest New Zealand. These deep, sheltered fiords are ideally suited for acoustic studies. This thesis presents the first detailed study of bottlenose dolphin acoustics in New Zealand. Both narrowband and broadband systems were used to record the vocalisations of two resident groups. Effort was distributed evenly over three years for both Doubtful Sound and Milford Sound. From 875 recordings, I proposed a repertoire of 15 discrete calls. These categories were subsequently compared using parameters measured from almost 2000 individual vocalisations. Various multivariate techniques revealed some redundancy in the proposed repertoire, and it was subsequently reduced to 12 calls. The 12 call repertoire was compared between the potentially interbreeding populations of Doubtful Sound and Milford Sound. Fiord-specificity was revealed for many of the calls, particularly the sequenced calls and whistles. These differences suggest bottlenose dolphins use dialects, in keeping with studies of killer whales and sperm whales. As Fiordland dolphins are out of sight for 90% of the time, acoustic techniques allow inference in to subsurface behaviour. I investigated sequential relationships among sounds and between sounds and behaviours. Many calls were strongly implicated in social interactions. The vocalisations ratchet, orca and the sequenced calls were associated with periods of conflict. A number of the click-based calls were linked to diving and presumed foraging events. Inference on the functional significance of sounds allowed an interpretation of habitat use. This appears to be the first study relating the entire vocal repertoire of a cetacean population to a complete home range. Areas important for socialising, foraging and resting are proposed. Local management decisions may be well served by this information. This study uses benign techniques to build on previous research in Fiordland, and adds a new dimension to the study of these populations.

Abstract:
Mestrado em Ecologia Aplicada
Ecological changes in the habitats, induced by climate change or the new paradigms of land use, have had enormous effects in the distribution of species, from the fragmentation of the populations to changes on the genome and/or their behavior. In the case of birds, these constraints may cause changes in vocal repertoires among isolated populations. It was recently confirmed that the two last populations of Red-billed Chough (Pyrrhocorax pyrrhocorax) resident in Portugal (populations of the Serra d'Aire e Candeeiros and Sagres) have an apparent gene-flow restriction, suggesting an isolation that is not explained only by the geographical distance that separates them. In fact, the species has a high dispersion capacity which can not itself justify this restriction of genes between these two populations. Being the species a corvid with a high cognitive capacity and gregarious species, the communication between individuals becomes a vital point to its survival. This work intends to investigate if the gene-flow restriction is due to a social segregation that can be reflected in the variations of the vocal repertoire between the two populations. The aim of this study was to describe and try to understand the main differences between the two populations, as well as possible variations among individuals of the same population (in this case, only in Serra d'Aire e Candeeiros). The results showed that the two studied populations have different repertoires, were described five call types from the population in the Serra d'Aire e Candeeiros and only four in the population of Sagres, thus not existing an evident common vocal repertoire between both populations. It was verified that among the populations the greatest differences are in the duration, maximum frequency and final frequency, where the population from Sagres has smaller durations and maximum frequencies and a higher final frequency than the population from Serra d'Aire e Candeeiros. In the case of the differences between individuals analysed at the intra-population level, these showed individual variations, namely peak frequency and ascending time. Overall, the results seem to corroborate the thesis that the genetic isolation of these populations can be attributed to communication and social barriers.
As mudanças no estado ecológico dos habitats, induzidas por alterações climáticas e/ou por novos paradigmas dos usos do solo, têm tido inúmeras consequências na distribuição das espécies, desde a fragmentação das populações, passando por mudanças no genoma e no seu comportamento. No caso das aves, estes constrangimentos poderão traduzir-se em mudanças nos repertórios vocais entre populações isoladas. Recentemente, confirmou-se que as duas últimas populações de Gralha de Bico Vermelho (Pyrrhocorax pyrrhocorax) residentes em Portugal (populações da Serra d’Aire e Candeeiros e de Sagres) apresentam uma aparente restrição de fluxo genético entre si, sugerindo um isolamento que não se explica apenas pela distância geográfica que as separa. De facto, a espécie apresenta uma elevada capacidade de dispersão o que não pode, só por si, justificar esta restrição de genes. Sendo a espécie um corvídeo com uma elevada capacidade cognitiva e gregária a comunicação entre indivíduos torna-se vital à sua sobrevivência. Este trabalho pretende investigar se a restrição do fluxo genético se deve a uma segregação social que pode refletir-se nas variações do repertório vocal entre as duas populações. Com este intuito, o presente estudo teve como objetivo descrever e tentar compreender quais as principais diferenças entre as duas populações, bem como possíveis variações entre indivíduos de uma mesma população (neste último caso apenas na Serra d’Aire e Candeeiros). Os resultados demonstraram que as duas populações estudadas exibiram repertórios diferentes, com a existência de cinco tipos de vocalizações para a população da Serra na Serra d’Aire e Candeeiros e apenas quatro na população de Sagres, não havendo uma partilha evidente de entre tipos de vocalização comuns a ambas as populações. Verificou-se que entre as populações as maiores diferenças estão na duração, frequência máxima e frequência final, sendo que na população de Sagres as vocalizações têm durações e frequências máximas menores e a frequência final maior que as da população de Serra d’Aire e Candeeiros. No caso das diferenças entre indivíduos analisados ao nível intra-populacional, estes mostraram variações individuais nomeadamente na frequência de pico e do tempo de ascensão. Globalmente, os resultados parecem corroborar a tese de que o isolamento genético destas populações pode ser imputável também a barreiras comunicacionais e sociais.

Abstract:
Summary Objective The purpose of this study was to describe the early vocalization skills in children with cleft lip and palate (CLP) at 6 and 12 months of age and compare these early vocalization measures to later speech and vocabulary development at 30 months of age. Methods The participants in the study included 13 children without cleft lip or palate (NCLP) who were typically developing and 13 children with CLP matched for age, gender and socioeconomic status. Standardized measures of cognition, language, hearing, and prelinguistic vocalization measures were administered at 6 and 12 months and speech production, and vocabulary measures were collected at 30 months of age. Results Group differences were observed in both receptive and expressive language development at 12 and 30 months of age. Group differences were observed in the frequency of babbling and Mean Babbling Level at 12 months and speech sound accuracy and vocabulary production at 30 months of age. Significant correlation coefficients were observed between babbling frequency at 6 months and consonant inventory size, vocabulary at 30 months for the children with clefts and PCC-R for noncleft children. Conclusions This study documented that young children with clefts have persistent vocalization and vocabulary deficits well beyond palate closure. Measures of babbling frequency, Mean Babbling Level and consonant inventories provide clinically effective means of identifying these early deficits. Additionally, these measures may provide a tool for monitoring the effects of early intervention programs that promote facilitation of sound and vocabulary development.
