VOCALE

A Tool for the Automatic annotation of vocalic and consonantal intervals

Vocale is being developed in the framework of the TIPAL project "Probabilistic Tools for Pattern Identification Applied to Linguistics" at the University Sao Paulo, where stochastic models are applied to describe rhythmic differences between European and Brazilian Portugese.
It is a tool for the automatic identification and annotation of vocalic and consonantal intervals in speech. These units are taken to represent good measurements of speech rhythm, and classification of languages into rhythmic classes using these units has been successful.
Vocale is based on the probabilistic measurement of relative entropy and a number of phonetic measurements as described in the algorithm.
Vocale takes a wav file as input, then automatically calls up some Praat functions such as creating a spectrogram and gives a Praat label file as output. This can then be used for the calculation of the speech rhythm. The entire programme is open source and can be downloaded.
