Abstract
A speech recognition method and apparatus for specific talker, used to compare one input tested speech and multiple pre-stored reference sample, consists of the steps: (1) Transforming input tested speech signal into one series of original speech parameter frame; (2) Using the above original speech parameter frame to decide start/end point of input speech, then according to start/end point of input speech deciding sound spectrum parameter frame series; (3) Using one nonlinear time domain normalization method transforming the above sound spectrum parameter frame series to speech feature parameter frame series with predetermined length; (4) Applying amplitude quantization normalization to the above speech feature parameter; (5) Comparing speech feature parameter of tested speech and speech feature parameter of all reference samples, and finding out reference sample most close to tested speech and reference sample next to most close tested speech; (6) According to reference sample most close to tested speech and reference sample next to most close tested speech, comparing its difference with one standard threshold, thereby deciding recognition result.
