Abstract : |
In this paper we present a new automatic male?female classi?cation method based on the location in the frequency domain of the ?rst 2 formants. This classi?cation is based on a new automatic formant extraction which is faster than a peak picking technique. Gender-dependent acoustic-phonetic models stemming from this classi?cation are used in the INRS Continuous speech recognition system with ATIS corpora. An improvement of 14 ? is obtained with these models in comparison to the baseline speaker-independent system. 1., |
