Abstract

Method and apparatus for reducing the amount of data sent when transmitting speech by obtaining the spectrum content of digital speech (406). First, analog speech is converted to digital speech (406). Then the digital speech is divided into frames and a spectrum analysis is performed on the frames (408). Frames with similar spectrum are combined (410). Then a second spectrum analysis is performed in predetermined steps (412). The data from the spectrum analysis of each frame is compressed and sent to a receiver (414). The receiver uses the data to reconstruct the frame (418). The frame is combined with other frames to reproduce the digital, signal (420). Then the digital signal is played back, thereby reproducing the analog speech (422).
