Patent ID: 7089186

Claim:
A speech information processing method comprising: a first extracting step of extracting a duration of an entire segment of a phonological series by using a speech file having plural learned samples and an information file having information necessary for extracting the duration; a first generating step of generating a duration model for the entire segment in consideration of a predetermined linguistic environment by using a phonemic/linguistic environment file having information on the linguistic environment and the information on the duration of the entire segment extracted in said first extracting step; a second extracting step of extracting a duration of a partial segment of the phonological series by using a speech file having plural learned samples and an information file having information necessary for extracting the duration; a second generating step of generating a duration model for the partial segment in consideration of a predetermined phonemic environment by using a phonemic/linguistic environment file having information on the phonemic environment and the information on the duration of the partial segment extracted in said second extracting step; a first obtaining step of obtaining a duration of the phonological series based on the duration model generated for the entire segment; a second obtaining step of obtaining a duration of each phoneme constructing the phonological series based on duration models generated for partial segments; a setting step of setting a duration of each of the phonemes so that the total duration of all the phonemes constructing the phonological series is substantially equal to the duration of the phonological series; and a speech synthesis step of synthesizing speech based on the duration of each of the phonemes set in said setting step.
