PURPOSE:To obtain a more natural composite voice by generating a signal for improving a tone quality in accordance with a phoneme parameter used for a composite filter. CONSTITUTION:A pulse signal related to pitch information from a pulse generating circuit 1, and a signal for improving a tone quality corresponding to pitch information outputted from a tone quality improving signal generating circuit 10 are synthesized by adding them by an adder 11 and a driving signal source for synthesizing a voice is obtained, and also, this driving signal is supplied to a composite filter 7. In this case, the signal for improving the tone quality is generated in accordance with a phoneme parameter through an input terminal group 9 used for the composite filter 7. Subsequently, the composite filter is driven by a signal based on this signal for improving the tone quality and the pulse signal for the pitch information. In such a way, a synthesized voice becomes near a more natural voice. |
