Function Documentation

int32 interp_all (  interp_t *  ip, int32 *  senscr, s3senid_t *  cimap, int32  n_ci_sen )

Interpolate each CD senone with its corresponding CI senone score. Returns: 0 if successful, -1 otherwise. Parameters: ip  In: Interpolation weights parameters senscr  In/Out: senscr[cd] interpolated with senscr[cimap[cd]], for cd >= n_ci_sen cimap  In: see senscr above n_ci_sen  In: see senscr above

int32 interp_cd_ci (  interp_t *  ip, int32 *  senscr, int32  cd, int32  ci )

Interpolate a single given CD senone with the given CI senone score. Returns: 0 if successful, -1 otherwise. Parameters: ip  In: Interpolation weights parameters senscr  In/Out: senscr[cd] interpolated with senscr[ci] cd  In: see senscr above ci  In: see senscr above

interp_t* interp_init (  const char *  interpfile, logmath_t *  logmath )

Read a set of CD/CI senone interpolation weights from the given file. Return value: pointer to interpolation structure created. Caller MUST NOT change its contents. Returns: an initialized interp_t structure
