PURPOSE:To give the nuance of a timbre characteristic to a sound signal to a sound which is modulated with a speech. CONSTITUTION:A musical sound signal with a scale specified by a scale specification part 1 is outputted from a musical sound generation part 13. This musical sound generation part 13 has output parts OUT1 and OUT2, and a 1st musical sound signal including harmonic frequencies in a wide band is outputted based upon the specified scale as a fundamental frequency from the OUT1 and a 2nd musical sound signal including only harmonic frequencies in a specific band is outputted from the OUT2. The musical sound signal from the out 1 and the musical sound signal from the OUT2 are modulated by a first and a 2nd spectrum modulation part 14, 15 by respective frequency bands with the external speech from a microphone part 4. Consequently, a musical sound signal which is affected greatly by the speech signal is outputted from the 1st spectrum modulation part 14 and a musical sound signal which is not affected by the speech signal so much is outputted from the 2nd spectrum modulation part 15. Both the outputs are mixed and supplied to an output part 8 through a power amplifier part 7, so that a sound is generated. |
