First International Conference on Spoken Language Processing (ICSLP 90)
We present in this paper the SAPHA system is developed for the purpose of the acoustic-phonetic decoding of standard Arabic. First of all, we give a description of the general architecture of the system and the various modules which compose it. Afterwards, we develop the principal stages of the Arabic decoder, namely : - segmentation of the speech signal into large phonetic classes. - automatic extraction of the parameters that are pertinent to phonetic recognition of standard Arabic. - multispeaker identification of phonemes in continuous speech by using an expert system based on production rules. The results obtained in broad phonetic classfication and phoneme labelling for three male speakers are also presented and discussed.
