METHOD AND DEVICE FOR BASIC FREQUENCY PATTERN GENERATION, SPEECH SYNTHESIZING DEVICE, BASIC FREQUENCY PATTERN GENERATING PROGRAM, AND SPEECH SYNTHESIZING PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a basic frequency pattern generating method capable of generating a basic frequency pattern of a voice close to the basic frequency pattern of a voice that a person utters. SOLUTION: A storage means is stored with a plurality of representative patterns representing by statistics static features at respective time-series points and dynamic features, representing features of variation of the static features, which constitute typical basic frequency patterns by meter control units as units of a voice having a time length of more than one syllable for controlling phonologic features of a voice corresponding to a text, a representative pattern corresponding to the text is selected out of the plurality of representative patterns stored in the storage means, and on the basis of statistics of the static features and statistics of the dynamic features of the selected representative pattern, the most likelihood estimation of the basic frequency pattern of the voice corresponding to the text is carried out.
