Abstract
A voice rule-synthesizer synthesizes a voice waveform based on the voice data stored in a database, which stores a large number of compressed voice data sections in a data stream. Each voice data section is stored as a plurality of frames compressed in a fixed-length frame format. The storage capacity of the database is reduced because the compressed voice data sections are stored as the data stream.
Claims19
A compressed voice-element data generator comprising a compression section for compressing a voice waveform of each voice data section by using fixed-length frames and historical data to generate compressed voice-element data, and a database for storing said compressed voice-element data while arranging said compressed voice-element data of a plurality of voice data sections in a data stream.
A voice rule-synthesizer comprising a voice-element data read section for reading and extending compressed voice-element data of a voice data section stored in a database, said database storing a singe data stream including a plurality of consecutive voice data sections each stored as a plurality of frames, and a waveform generator for synthesizing a voice waveform based on said voice-element data of a desired number of said frames extended by said voice-element read section.
A method for synthesizing a voice waveform comprising the steps of:
- compressing a voice waveform of each voice data section by using fixed-length frames and historical data to generate compressed voice-element data, storing said compressed voice-element data while arranging said compressed voice-element data of a plurality of voice data sections in a data stream, extending said compressed voice-element data of each voice data section to generate an extended voice-element data, and synthesizing a voice waveform based on said extended voice-element data.
