Abstract

A system is provided for voice signal processing including recognizing input voice messages and generating output voice messages. Digital processing of voice signals yields particular advantages. Voice responsive operations provide operator interaction flexibility. Communication of digital information in response to voice information provides data compression for communication applications. Other applications of the voice signal processing system include an audionic clock, an audionic calculator, and an audionic announciator.
