A multi-level approach to speech rate in British English: towards an analysis-by-synthesis method

Cyril Auran and Caroline Bouzon, Univ Lille 3

This paper provides a detailed account of the durational differences induced at different structural levels (inter-silence segments, rhythmic units, syllables, syllabic constituents, phones) by changes in speech rate from normal to slow speech in read British English. Using the data described in this study, we present preliminary results concerning a regression tree model predicting phone durations in slow speech with an average precision of 16 ms in slow speech.
