Abstract :
This paper describes an isolated-word, speaker independent, speech recognition system based on neural networks. The system was developed for a 32 words vocabulary including the digits, movement commands and arithmetic operation commands. The recognition rate achieved for a directly recorded speech, band-limited to 3.4 kHz, was greater than 96%
