ABSTRACT:
A speech recognition method is implemented with an image pickup apparatus such as a TV camera which picks up a lip image during speech and with a small computer which has a small memory capacity and is connected to the TV camera. The computer receives and processes as lip data an image signal from the TV camera which represents the lip image. The lip data is collated with language data stored in the memory of the computer so as to select the language corresponding to the lip data, thereby recognizing the speech. A microphone may also be provided to output to the system a voice waveform signal serving as voice data. This voice data is collated with the language data stored in the memory of the computer to select the language corresponding to the voice data, thereby recognizing the speech on the basis of the language selected using the lip data and using the voice data. Image pattern data and voice pattern data may be extracted and processed for every word, or for every unit sound. With the inventive method, the speech recognition ratio and processing speed are improved, particularly with respect to use of a computer with a small memory capacity.
