VOICE RECOGNITION.

摘要

Voice signals are picked up through a microphone (31) and voice sections are detected by a voice section detector (32). The voice signals are then processed with every predetermined time interval by a frequency analyser (33) having a predetermined number of channels, and the voice signal portions core corresponding to respective channels are quantised. The quantised data obtained from these channels are converted into binary data (34) to form frames each composed of a series of binary data. Each data of the frame corresponds to a channel and is preferably set to an integer number of times of the operation unit of a c computer. When a synthetic frame is to be formed by superposing two or more of such frames, the synthetic frame is divided into hierarchies so that each bit may be displayed by binary notation in each hierarchy. It is further possible to divide a frame into a number of subframes in order to effect preparatory comparison using the subframes.
