Abstract
Abstract A voice synthesizing apparatus is arranged to synthesize a voice from text data composed of either character codes or a series of symbols by generating a sound source based on a series of sound-source parameters and synthesizing the sound source on the basis of a series of synthesis parameters. The voice synthesizing apparatus is provided with a sound-source generating circuit for generating the aforesaid sound source from a signal obtained from an instrumental sound generated with a musical instrument. This arrangement serves to easily synthesize voices which convey language information and yet which simulate the sounds of musical instruments such as a guitar, a violin, a harmonica, a musical synthesizer and the like.
