US 2006/0224380 A1 · Pitch pattern generating method and pitch pattern generating apparatus

Abstract

A pitch pattern generating method includes preparing a memory to store a plurality of pitch patterns each extracted from natural speech, and pattern attribute information corresponding to the pitch patterns, inputting language attribute information obtained by analyzing a text including prosody control units, selecting, from the pitch patterns stored in the memory, a group of pitch patterns corresponding to each of the prosody control units based on the language attribute information, to obtain a plurality of groups corresponding to the prosody control units respectively, generating a new pitch pattern corresponding to the each of prosody control units by fusing pitch patterns of the group, to obtain a plurality of new pitch patterns corresponding to the prosody control units respectively, and generating a pitch pattern corresponding to the text based on the new pitch patterns.
