1. A voice-actuated pseudo-articulate sound generator, comprising:

  • sound responsive detector means for producing an electrical signal having an amplitude envelope indicative of an actuating voice;

    delay means coupled to the detector means for delaying said electrical signal having said amplitude envelope for a predetermined period of time;

    frequency generator means for providing a modulation signal having a randomly varying frequency;

    means coupled to receive the delayed electrical signal having said amplitude envelope and the modulation signal to produce an audio output signal having an amplitude corresponding to that of the delayed electrical signal and a pitch corresponding to the modulation signal; and

    means for transforming the audio output signal to sound having an amplitude envelope corresponding to said amplitude envelope of the activating voice.
