Abstract
To produce a signal simulating the characteristics of the average human voice, a basic periodic waveform with generally sinusoidal sections separated by level sections is passed through a first filter for substantially equalizing its frequency components and is then shaped in a second filter whose transfer function approximates that of the vocal tract in a frequency band of 0 to 4 kHz. The basic waveform fed to the first filter may be modulated in amplitude and/or recurrence period by a pseudorandom signal from an ancillary generator.
