Abstract Purpose: The sudden emergence of a foreign accent in an individual's native language has been described in the literature for over 60 years. In one of the most famous cases, the terms prosody and dysprosody first were introduced to the literature. The purpose of this paper is to summarize the prosodic changes seen in the foreign accent syndrome (FAS) and to review its etiology and clinical course. Method: Case studies were reviewed, with an emphasis on information about clinical presentation and course and on speech changes affecting stress, rate, duration, and intonation. Results and Conclusions: In the majority of published cases with FAS, there has been documented focal brain injury in the left cerebral hemisphere, and the foreign accent has emerged after a period of recovery from muteness, nonfluent aphasia, and/or motor speech disorder. In other cases, a psychogenic etiology has been established or suggested. Stress, rate, and duration changes are similar to those seen in nonfluent aphasia and apraxia of speech, whereas intonation changes are more specific to the foreign accent presentation. Information about recovery and psychosocial consequences of the accented speech is sparse and these areas are in need of further study. In particular, there is a need for detailed and clinically oriented case studies with longitudinal follow-up.

This work deals with designing and testing of new acoustic features for analysis of dysprosodic speech occurring in hypokinetic dysarthria patients. 41 new features for dysprosody quantification (describing melody, loudness, rhythm and pace) are presented and tested in this work. New features can be divided into 7 groups. Inside the groups, features vary by the used statistical values. First four groups are based on absolute differences and cumulative sums of fundamental frequency and short-time energy of the signal. Fifth group contains features based on multiples of this fundamental frequency and short-time energy combined into one global intonation feature. Sixth group contains global time features, which are made of divisions between conventional rhythm and pace features. Last group contains global features for quantification of whole dysprosody, made of divisions between global intonation and global time features. All features were tested on Czech Parkinsonian speech database PARCZ. First, kernel density estimation was made and plotted for all features. Then correlation analysis with medicinal metadata was made, first for all the features, then for global features only. Next classification and regression analysis were made, using classification and regression trees algorithm (CART). This analysis was first made for all the features separately, then for all the data at once and eventually a sequential floating feature selection was made, to find out the best fitting combination of features for the current matter. Even though none of the features emerged as a universal best, there were a few features, that were appearing as one of the best repeatedly and also there was a trend that there was a bigger drop between the best and the second best feature, marking it as a much better feature for the given matter, than the rest of the tested. Results are included in the conclusion together with the discussion.

L'objectif de ce travail est d'observer la prosodie dans un cas de parole pathologique, l'Aphasie Progressive Primaire (A. P. P. ). Un suivi longitudinal de l'évolution de la pathologie a permis d'étudier les variations temporelles de la parole qui accompagnent la dégénérescence. Nous proposons une analyse comparée de différents types de tâches (répétition, lecture, dénomination) produites par le même patient. Le corpus est constitué d'un bilan d'aphasie (B. D. A. E. ), enregistré sept fois au cours des deux premières années de développement de l'A. P. P. Nous proposons deux axes de recherche : (1) une analyse de l'organisation temporelle des phénomènes cognitifs nécessaires à la réalisation de la tâche ; (2) une analyse de l'organisation temporelle centrée sur les aspects phonétiques et phonologiques des productions du patient. L'ensemble des résultats confirme l'influence sélective de la dégénérescence sur les variables temporelles en production de parole.

Viktiga aspekter av kommunikationen styrs från höger hjärnhalva, däribland emotionell prosodi. Forskningen inom detta område har dock hittills varit ganska begränsad. En aspekt, som inte undersökts än, är jämförelse av deltagarens egen och lyssnares skattning av röstens uttrycksfullhet. Syftet med studien vara att undersöka förmågan att uttrycka emotionell prosodi efter stroke i höger hemisfär. Deltagare var tre patienter med stroke i höger hemisfär samt tre kontrollpersoner utan neurologisk sjukdom/skada eller problem med tal eller röst. Sammansättningen i grupperna av deltagare med stroke respektive kontrollpersoner var likvärdig avseende kön, ålder, dialektområde och utbildningsnivå. Emotionell prosodi undersöktes genom flera metoder: akustisk analys av grundtonsvariation samt deltagarnas egen såväl som lyssnares skattning av röstens uttrycksfullhet. I resultaten framkommer tendenser, som indikerar en skillnad mellan deltagarna med stroke i höger hemisfär och kontrollpersonerna. För deltagarna med stroke sågs mindre grundtonsvariation och lägre skattningar av röstens uttrycksfullhet. Då deltagarantalet var litet, bör resultaten tolkas med försiktighet. De tendenser till skillnader mellan försöks- och kontrollpersonerna som ses i resultaten motiverar dock för vidare studier. Important aspects of communication, including emotional prosody, are regulated from the right hemisphere. However, the research in the area of emotional prosody has so far been rather limited. One of the aspects that have not been examined yet is the comparison of the participant’s own rating of voice expression with ratings by listeners. The aim of the study was to assess expressive emotional prosody after right-hemisphere stroke. Participants were three patients with right-hemisphere stroke and three controls without neurological conditions or problems regarding speech or voice. The groups of participants with stroke and the controls were matched regarding sex, age, dialect and level of education. Emotional prosody was examined using multiple methods: acoustic analysis of variation in fundamental frequency and the participants’ own as well as listeners’ rating of voice expression. The results show tendencies that indicate a difference between the participants with right-hemisphere stroke and the controls. The participants with stroke showed smaller variations in fundamental frequency and lower ratings of voice expression. Due to the small sample size in the present study, results should be treated with caution. However, the tendencies shown in the results regarding differences between subjects and controls would justify further studies.

One
of the key features of the hypokinetic dysarthria associated with Parkinson
disease is dysprosody. While there has been ample research into the global
characterization of speech in Parkinson disease, little is known about how
people with Parkinson disease mark lexical stress. This study aimed to determine
how people with Parkinson disease modulate pitch, intensity, duration, and
vowel space to differentiate between two common lexical stress patterns in
English: trochees (strong-weak pattern) and iambs (weak-strong pattern), in two
syllable words. Twelve participants with mild to moderate idiopathic Parkinson
disease and twelve age- and sex-matched controls completed a series of speech
tasks designed to elicit token words of interest in prosodically-relevant speech
tasks (picture identification (in isolation and lists) and giving directions
(spontaneous speech). Results revealed that people with Parkinson disease produced
a higher overall pitch and a smaller vowel space as compared to controls,
though most lexical marking features were not significantly different. Importantly,
the elicitation task had a significant effect on most dependent measures. Although
lexical stress is not significantly impacted by Parkinson disease, we recommend
that future research and clinical practice focus more on the use of spontaneous
speech tasks rather than isolated words or lists of words due to the
differences in the marking of lexical stress in the latter tasks, making them
less useful as ecologically-valid assessments of prosody in everyday
communication.
