S3DECODER_EXPORT void utt_begin (  kb_t *  kb  )

Begin utterance Parameters: kb  A kb

S3DECODER_EXPORT void utt_decode (  void *  data, utt_res_t *  ur, int32  sf, int32  ef, char *  uttid )

Decoding the whole utterance Parameters: data  A kb ur  Utterance resource structure sf  Starting frame of the decoding ef  Ending frame of the decoding uttid  Utterance ID

S3DECODER_EXPORT void utt_decode_block (  float ***  block_feat, int32  block_nfeatvec, int32 *  curfrm, kb_t *  kb )

This function decodes a block of incoming feature vectors. Feature vectors have to be computed by the calling routine. The utterance level index of the last feature vector decoded (before the current block) must be passed. The current status of the decode is stored in the kb structure that is passed in.

S3DECODER_EXPORT void utt_end (  kb_t *  kb  )

End utterance Parameters: kb  A kb
