Abstract
A voice activated echo generator employs digital voice recording technology to digitize several spoken words of audio using low-cost encoding techniques. The audio information is stored in dynamic memory and is played back by reconverting the data back from its digitized form to audio, which then drives a loudspeaker. The echo generator has many design parameters which can be varied, such as, duration of recorded speech, voice actuation sensitivity, number of playback repetitions, speech quality, playback speed, playback pitch, and playback volume. For a toy, an input speech threshold initiates a distinct record interval followed by a substantially immediate and automatic playback interval during which the echo is generated without the problem of acoustic feedback.
