Results are reported of experiments in the use of Charade, an Automatic Learning System, to classify phonetic macro-classes. A preliminary evaluation of the Charade system is carried out on a reference database of continuous speech and compared to an usual classifier (i.e., Hamming Distance Nearest Neighbor) and a neural net based technique (i.e., Modified Hopfied Net). Preliminary results of classification of phonetic macro-classes can be summarized as follows :

Spectral masks of vowel, drawn from analysis of the most frequent clustering rules found for each of them, are shown to be coherent with phonetic knowledge.
