Abstract
An Interactive Voice Recognition and Speech Synthesis Clock Radio wherein the voice recognition circuitry is trained to recognize a number of predetermined phrases spoken by one or more specific users. The speech synthesis circuitry includes a number of predetermined phrases generated in response to verbal utterances by a user.
Claims26
An interactive voice recognition and voice synthesis digital clock, comprising:
- a DC source of power;
- a microphone for converting audible human speech into first electrical signals representing said human speech;
- a source of periodic pulse signals for use as clocking signals;
- a microprocessor connected to said microphone, said DC source of power, and connected to receive said clocking signals, said microprocessor including:
- clocking circuitry for providing second electrical signals for controlling at least the time indicated by a digital clock display,
- speech synthesis circuitry for generating third electrical signals representative of selected output speech phrases in response to receiving selected control signals,
- input speech circuitry for receiving and analyzing said first electrical signals, and said microprocessor generating said selected control signals for controlling outputs of said clocking circuitry and said speech synthesis circuitry in response to said analyzing of said first electrical signals, said microprocessor providing first ones of said selected control signals if said speech circuitry failed to recognize said first electrical signals as representing a predetermined input speech phrases and providing second ones of said selected control signals if said speech circuitry recognizes said first electrical signals as representing a predetermined input speech phrase,
- first memory cooperating with said microprocessor for storing data required by said microprocessor to process said first electrical signals and to determine if at least a part of said first electrical signals represents at least one of said predetermined input speech phrases;
- second memory cooperating with said speech synthesis circuitry of said microprocessor for storing data required to generate said third electrical signals in response to receiving said first ones of said selected control signals;
- a sound producing device connected to said microprocessor for receiving said third electrical signals from said speech synthesis circuitry and for converting said electrical signals into audible sounds representative of said output phrases;
- and
- a digital display for receiving said second electrical signals from said clocking circuit and for providing a clock display.
