ABSTRACT:
From a speech signal, spectrum information as a plurality of line spectrum data, pitch position data and amplitude data are extracted. Each of the sinusoidal wave signals of different frequencies is allotted to the predetermined line spectrum data. The frequency of the sinusoidal wave signal is changed with the pitch position being the boundary. The plurality of sinusoidal wave signals are added and the added result is modulated by the amplitude data to transmit the modulated signal as the transmission data. The line spectrum data, the pitch position data and amplitude data are extracted from the modulated signal. The replica of the speech is produced on the basis of these extracted data.
