Pitch pattern generating method and pitch pattern generating apparatus
First Claim
1. A pitch pattern generating method comprising:
- 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.

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.

13. A pitch pattern generating apparatus comprising:
-
a memory to store a plurality of pitch patterns each extracted from natural speech, and pattern attribute information corresponding to the pitch patterns;
an input unit configured to input language attribute information obtained by analyzing a text including prosody control units;
a selecting unit configured to select, 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;
a first generating unit configured to generate 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
a second generating unit configured to generate a pitch pattern corresponding to the text based on the new pitch patterns. - View Dependent Claims (14, 15, 16, 17, 18, 19)
