Acoustic signal recognition with a photorefractive time-delay neural network.
We present a photorefractive processor for audio-acoustic signal recognition based on the time-delay neural network model of Hopfield and Tank [in Neural Models of Plasticity, J. H. Byrne, ed. (Academic, New York, 1989), p. 363-377]. We demonstrate the recognition of three words by programming the interconnection weights of the time-delay network.
