ABSTRACT:
A speech encoding method, a speech decoding method and corresponding apparatus capable of outputting non-buzzing spontaneous playback speech in a voiced portion includes a sinusoidal analysis encoding unit on the decoder side that detects the pitch of the voiced portion of the input speech signal. The pitch intensity information, which is a parameter containing the information representing not only the pitch intensity of the input speech signal but also the information representing proximity to the voiced speech or the unvoiced speech of the speech signal, is generated by a voiced/unvoiced (V/UV) discrimination unit and pitch intensity information generating circuit. The pitch intensity data is sent along with the encoded speech signal to the encoding side which then adds the noise component controlled on the basis of the pitch intensity information to the voiced portion of the encoded speech signal in a voiced speech synthesis portion and decodes and outputs the resulting signal.
