Communication Accommodation Theory

Edited by Howard Giles

Most people modify their ways of speaking, writing, texting, and e-mailing, and so on, according to the people with whom they are communicating. This fascinating book asks why we 'accommodate' to others in this way, and explores the various social consequences arising from it.

Abstract: This study focuses on the temporal analysis of stops /p b t d k ɡ/ and devoicing analysis of voiced stops /b d ɡ/ produced in different word positions by six native speakers of European Portuguese. The study explores acoustic properties related to voicing. The following acoustic properties were measured: voice onset time (VOT), stop duration, closure duration, release duration, voicing into closure duration, duration of the preceding vowel and duration of the following vowel. Results suggested that when [b d ɡ] were devoiced, the acoustic properties stop duration, closure duration, duration of the following vowel, duration of the preceding vowel and duration of voicing into closure were relevant for the voicing distinction. Implications for research and practice in speech and language therapy are discussed. Further investigation is needed to find how the productions analysed in the present study were perceived by listeners, specifically productions of devoiced stops.
