AboutVLABS
Abstract— We propose a simple speech compression algorithm
using subband division and ADPCM (Adaptive Differential
Pulse Code Modulation) algorithm. Although speech data are
stored in a semiconductor memory device, its capacity and the
available network capacity are limited. Therefore, it is necessary to
compress the data as much as possible. The first is that the
reconstructed datum must be understood correctly. Speech signal is
compressed with a ratio of 1/4 using the proposed subband division
and ADPCM (Adaptive Differential Pulse Code
Modulation) algorithm.
