Voice responsive "talking" toy










Image Number 3 for United States Patent #4221927.

A toy which, in response to a complex sound such as human speech generates a train of audio pulses. The pulses are psuedo-random with respect to frequency composition and to duration, thus simulating syllabic speech. Provisions are also described whereby the length of the pulse train is made random.
