Abstract
A voice processing method and system using voice power is provided. A voice power signal is produced in analog format and this voice power signal is sampled at a predetermined time interval to determine its current envelope or amplitude, which is then compared with a predetermined number of voice power levels, whereby "1" is assigned to at least one of the predetermined number of voice power levels which corresponds in level to the amplitude thus determined and "0" is assigned to the rest of the predetermined number of voice power levels, thereby converting the analog voice power signal into a binary voice power pattern. In the preferred embodiment, the voice signal is also processed through a frequency analyzer including a plurality of band-pass filters different in frequency range and a binary converter to form a binary time-frequency voice distribution pattern which is then combined with the binary voice power pattern to form a combined voice pattern. As a modification, a voice power range is determined by multiplying a predetermined threshold to the amplitude, and the voice power pattern is compared with the predetermined number of voice power levels.
