Device for digital recognition of speech. A recording of the signal generates the elementary reference unit of the signal to which a digital value is assigned; an oscillating circuit and a logic circuit 5 allocate a digital value to each of the electrical signals as a function of their frequencies, which frequencies are subjected to a mathematical processing 7 so as to obtain a particular digital value after a specified time; a logic circuit preserves in memory 8 the digital values arising from the mathematical processing 7; comparison 9 of the signals is carried out after computation 10; a sensor 3 simultaneously records the time, amplitude and frequency of the signal transmitted to the logic circuits of the totaliser; for each frequency of the signal, a computation is carried out using the logic circuits for computation 10, memory 8 and comparison 9. Voice-operated devices such as access controls or language translators. <IMAGE> |
