<p>PURPOSE: To provide an inexpensive voice synthesizer for synthesizing human voice from a coded parameter stored in a solid state element or inputted from the external. CONSTITUTION: The voice synthesizer 10 (12A, 12B) is controlled by a programmed microprocessor 19 and uses data coding and compression technique to reduce a data ratio. A coded parameter is used for controlling the reflection characteristic of a digital filter included in the synthesizer 10 and an output from the digital filter is applied to a digital/analog converter. Thereby the digital output from the filter is converted into a sound signal, which is sent to a conventional amplifier 20 and a speaker 5.</p> |
