Automatic extraction of the general tendency of F0 patterns Cross linguistic study on laboratory data
Résumé
The goal of our study is to use an automatic approach to extract the general prosodic tendencies of the speech signal conveyed by the F0 pattern. The speech signal is prosodically annotated by an automatic prosodic transcriber and then prosodic patterns are extracted from this annotation. The pertinence of the pattern extraction is tested here on laboratory data containing isolated sentences in French and English uttered by native and nonnative speakers. An analysis of the extracted parameters shows how the prosody of the sentences is defined by their shared syntactic structures and also indicates to what extent the prosodic features used by the two languages are similar or different. It appears from the analyzed data that the extraction of parameters via automatic processing can yield relevant information for a cross-linguistic study of prosody.
