Abstract
Abstract A timepiece whose functions are controlled by making a voice instead of operating manual switches. Operating signals for functioning the timepiece, except for turning off of the alarm sound, are applied to a voice recognizing circuit. Operation of turning off of the alarm sound is performed by detecting a volume level of voice which is made by the user. Thus, it eliminates difficulty to recognize only the voice of the user while the alarm sound is generated because the voice of the user and the alarm sound are mixed together.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
239 words
In a voice recognizing alarm timepiece including a timing cirucit which counts the current time, an alarm circuit which outputs a coincident signal when the current time counted by said timing circuit coincides with a predetermined time, a sound generating circuit which generates a sound by receiving said coincident signal, an alarm control circuit which controls whether to supply said coincident signal to said sound generating circuit or not, a microphone which detects an external voice, a voice recognizing circuit which outputs a recognizing signal by recognizing whether said external voice detected by said microphone corresponds to one of the stored voices or not, a decoder which supplies to said alarm control circuit the alarm turn on signal allowing said coincident signal to be supplied to said sound generating circuit and the alarm turn off signal preventing said coincident signal from being supplied to said sound generating circuit, upon receipt of said recognizing signal, and said timepiece includes: a low-pass filter which eliminates high frequency components in said voice signal from said microphone; a level detector which outputs a detected signal whenever the volume level of said voice signal through said low-pass filter is higher than predetermined level; and a gating circuit which receives said detected signal from said level detector and supplies said alarm turn off signal to said alarm control circuit when said coincident signal from said alarm control circuit is supplied to said sound generating circuit.

Claim 3

In a voice recognizing alarm timepiece including a timing circuit which counts the current time, an alarm circuit which outputs a coincident signal when the current time counted by said timing circuit coincides with a predetermined time, a sound generating circuit which generates a sound by receiving said coincident signal, an alarm control circuit which controls whether to supply said coincident signal to said sound generating circuit or not, a microphone which detects an external voice, a voice recognizing circuit which outputs a recognizing signal by recognizing whether said external voice detected by said microphone corresponds to one of the stored voices or not, a decoder which supplies to said alarm control circuit the alarm turn on signal allowing said coincident signal to be supplied to said sound generating circuit and the alarm turn off signal preventing said coincident signal from being supplied to said sound generating circuit, upon receiving said recognizing signal, and said timepiece includes: a timing signal generating circuit which generates a first timing signal and then generates a second timing signal continuously after said coincident signal from said alarm circuit is generated; an A-D converter which converts the volume level of said voice signal detected by said microphone into digital data; a memory which stores said digital data by responding to the generation of said first timing signal; a comparator which outputs a signal when the digital data from said A-D converter is greater than the digital data stored in said memory; and a gating circuit which receives said detected signal from said level detector and supplies said alarm turn off signals to said alarm control circuit when said coincident signal from said alarm control circuit is supplied to said sound generating circuit.
