Device to control machines by voice
First Claim
1. A voice control system responsive to a sequence of predetermined different audio frequency signals to generate a digital control output signal comprising:
- (a) audio conversion means responsive to a predetermined audio frequency signal for generating a digital number signal proportional to the audio frequency;
(b) storage means for storing predetermined program data and also for temporarily storing data including each of a sequence of digital number signals generated by said audio conversion means;
(c) output signal memory means for storing digital control output signals; and
(d) data processing means coupled to each of said audio conversion means, storage means and output signal memory means for transferring signals and controlling the system in response to said predetermined program data stored in said storage means, said predetermined program data including(1) a ratio generation routine for generating a sequence of ratio number signals by dividing each of the stored sequence of digital number signals by one of the digital number signals, and(2) a ratio number conversion routine for converting a sequence of stored ratio number signals into a digital control output signal for storage in said output signal memory means.

Abstract
A device to control machines by voice is disclosed which responds to a plurality of predetermined musical tones in a sequence to generate a digital control output signal. Audio conversion means convert the sequence of tones into a corresponding sequence of digital number signals which are temporarily stored in a memory. Then a sequence of ratio signals are generated by dividing each of the digital number signals by one of the digital number signals. The resulting sequence of ratio signals is then converted into a corresponding sequence of digital numbers which comprises the digital control output signal. A microprocessor and associated storage processes the digital data and controls the conversion of the musical tones into corresponding digital numbers.
