Résumé/abstract:
The presentation is concerning MISTRAL+, the upgraded version of an automatic tool created in 2004 named INTSMEL then MELISM. Since MELISM, the entire process has been modified in order to simplify and enhance the study of languages. MISTRAL+ is a combination of two modules: a Praat plugin MISTRAL_Praat, and MISTRAL_xls.
For specific corpora, it performs melodic / tonal annotation based on the F0 variation in prominent words, but also in any chunk of speech, prominent or not. So this tool while being specialized can also be used as a generic one. It is particularly convenient for the study of tonal languages.
Now among others, new functions allow to use API symbols while labeling, and to provide a semi-automatic melodic annotation in the frame of tonal languages. The program contains several functions which compute target points (or significant points) to model F0 contour, perform automatic annotation of different shapes (F0 in Hz, semi-tones and in tone levels, tonal dynamics, duration, F0 derivative), and export all the data in an xls file. This tool has been designed in order to fit for user needs: so its conviviality was an important point of this new version.
In a first part of this presentation, the MISTRAL+ functions will be described, and in a second part, 3 examples of application will be presented about the phonetic study at linguistic and Pi languages (speech automatic recognition) levels, and then about the tonal domain, all concerning the case of a tonal language of south-Asia, the Mo Piu endangered language studied in the frame of the MICA Au Co Project.
