An Investigation of the Relation Between Perceived Pitch Accent and Automatically-Located Accent in British English

Previous work on the prosodic analysis of British English has used a purely perceptual analysis of the data, the results being stated in terms of structural features of the prosodic unit (eg. length of tone-unit, type of nucleus or head pattern). However, this type of analysis makes no reference to the acoustic exponents of prosodic features, and so does not make it possible to study the physical parameters that are giving rise to a given perceptual category. This means in turn that it is not possible to extract reliable intonation generation and detection information automatically. The work to be reported here begins to remedy the situation by studying the performance of an automatic intonation detection algorithm when compared against perceptually labelled intonation for the same speech data. The acoustic correlates of perceived stress are compared with rather more rigid acoustic measurements used by the algorithm. KEYWORDS: Intonation, Prosody, Sentence Level Stress, Automatic intonation detection
