SPEECH PROCESSING METHOD AND APPARATUS AND PROGRAM THEREFOR

摘要

PROBLEM TO BE SOLVED: To judge a speech state which does not depend on a speaker. SOLUTION: A speech parameters vector consists of the groups of speech parameters which comprises at least one of a fundamental frequency, power, and temporal variation of a dynamic measure, or at least one of the inter-frame differences. A code file stores appearance probabilities in the emphasizing and tranquil states of the speech parameters vector respectively at each code. The appearance probabilities are respectively obtained in the emphasizing and tranquil states of the corresponding speech parameters vector which is obtained by quantizing the groups of the speech parameters provided from an input speech at each frame through the use of the code book. Thus, it is determined whether the state is the emphasizing one or not by comparing the probabilities. COPYRIGHT: (C)2004,JPO
