Automatic labelling of pitch levels and pitch movements in speech corpora

Boekbijdrage - Boekhoofdstuk Conferentiebijdrage

We describe a system for the automatic labelling of pitch levels and pitch movements in speech corpora.Five pitch levels are defined: Bottom and Top of the speaker’s pitch range, as well as Low, Mid, and High, which are determined on the basis of pitch changes in the local context. Five elementary pitch movements of individual syllables are distinguished on the basis of direction (rise, fall, level) and size (large and small melodic intervals, adjusted to the speaker’s pitch range). Compound movements consist of a concatenation of simple ones.The labelling system combines several processing steps: segmentation into syllabic nuclei, pause detection, pitch stylization, pitch range estimation, pitch movement classification, and pitch level assignment. Unlike commonly used supervised learning techniques the system does not require a labelled training corpus. This approach results in an automatic, fine-grained and readable annotation, which is language-independent, speaker-independent and does not depend upon a particular phonological model of prosody.
