Filed: 1996-06-27
Abstract: PROBLEM TO BE SOLVED: To promote mastication by counting the detecting output of a mastication detecting means and informing when the counted value amounts to a previously set prescribed value so as to awake an auditory sense by stimulation at meals. SOLUTION: The mastication detecting means A consists of a transducer 1, an amplifier circuit 2 and a wave forming circuit 3.

In this case, a counter 6 counts a pulse from the means A. A decoder 7 fetches data in the counter 6 to output from each output terminal when its counted value becomes the prescribed value. Then a speech signal generation circuit 8 consisting of LSI generates a speech signal based on the output of the decoder.
