  • segmented a training speech syllable into an initial part and a final part;

    training a Continuous Hidden Markov Model (CHMM) on the initial part to create an initial part model having trained initial part model parameters;

    training a CHMM on the final part to create a final part model having trained final part model parameters;

    training a CHMM on the training speech syllable to create a syllable model using the trained initial part parameter values and the trained final part parameter values as starting parameters for the syllable model;

    operating on an object speech sample with the syllable model;

    recognizing the object speech sample as an object speech syllable based on a degree of match of the object speech sample to the syllable model;

    representing the object speech sample as a Chinese character in accordance with the object speech syllable.
