Speech recognition apparatus and method performing speech recognition with feature parameter preceding lead voiced sound as feature parameter of lead consonant

摘要

A lead consonant buffer stores a feature parameter preceding a lead voiced sound detected by a voiced sound detector as a feature parameter of a lead consonant. A matching processing unit performs matching processing of a feature parameter of a lead consonant stored in the lead consonant buffer with a feature parameter of a registered pattern. Hence, the matching processing unit can perform matching processing reflecting information on a lead consonant even when no lead consonant can be detected due to a noise.
