Abstract
The reception terminal receives a code series from the communication path. The separator separates the code series into a speech code series and text information. The speech code series is decoded into a pitch period, a LSP coefficient, and code numerals by the synthesizer to reproduce the speech sound in the CELP system. Also, the text information is converted into pronunciation and accent information by the language analyzer and added to prosody information, such as phoneme time length and pitch pattern by the prosody generator. The LSP coefficient, and code numerals suitable for the phoneme are read from the segment database and the pitch frequency from the prosody information is inputted to the synthesizer and synthesized into speech sound.
