Intonation characteristics (mean F0, standard deviation of F0, and F0 difference) and speaker rate (duration) were assessed in 40 matched statement–question pairs produced by 40 normal adult speakers of Canadian French, similar to Eady and Cooper [J. Acoust. Soc. Am. 80, 402–415 (1986)] for American English. Subgroups were also compared by both sex (male versus female) and age (younger versus older subjects). Results revealed a greater difference in fundamental frequency between statement–question pairs than reported by Eady and Cooper, as well as a previously unreported interaction between sentence duration and sentence type. There were also age-related differences in both intonation and rate.
Des données acoustiques sont proposées pour faciliter l’valuation de la parole de patients présentant des troubles de la prosodie tels la dysarthrie. Ces données ont été recueillies auprès de 40 sujets francophones, sans maladie neurologique ni trouble de la communication, ayant entre 45 et 75 ans, répartis en quatre groupes selon le sexe et l’âge. Les sujets ont été invites à produire quatre series de 20 phrases interrogatives et declaratives et leurs productions ont été enregistrées et analysées au moyen du logiciel Speech Viewer de IBM. Des mesures de frequence fondamentale sur l’ensemble de la phrase, de variation de la frequence fondamentale, de debit et d’intonation (difference de frequence fondamentale entre phrases interrogatives et declaratives) sont rapportées sous forme de tableaux pour utilisation clinique. Ces informations permettront de combler une lacune dans l’evaluation de la prosodie de la parole de personnes francophones.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
