Abstract
A method () and apparatus () for segmenting a sequence of audio samples into homogeneous segments (and) are disclosed. The method () forms a sequence of frames (to) along the sequence of audio samples, and extracts, for each frame, a data feature. The data features form a sequence of data features. Transition points in the sequence of data features are thin detected by applying the Bayesian Information Criterion to the sequence of data features. The transition points define the homogeneous segments (and). Preferably the data feature is single-dimensional and a leptokurtic distribution is used as an event model in the Bayesian Information Criterion.
