Method and apparatus for speech recognition using both low-order and high-order parameter analyzation |
摘要 |
A speech recognition apparatus includes a a low-order parameter analyzation section for deriving low-order parameter time series of an input speech, a start and end point detection section for detecting the start and end points of the input speech by use of the parameter time series derived by the low-order parameter analyzation section, a high-order parameter analyzation section for deriving high order parameters at preset sampling points from the input speech of a range corresponding to the start and end points detected by the start and end point detection section, a pattern matching section for matching feature parameters corresponding to the parameters derived by the high-order parameter analyzation section with standard parameters previously registered and deriving similarities between the matched parameters, and a recognition result outputting section for outputting the recognition result for the input speech according to the similarities derived by the pattern matching section.
