Research abstract
SECURE VOICE COMMUNICATIONS OVER NARROW (10 - 12.5 KHZ) CHANNELS IS BECOMING INCREASINGLY IMPORTANT. SPEECH COMPRESSIION FOR USE OVER SUCH NARROW CHANNELS MUST OPERATE AT 9.6 KBPS. EXISTING SPEECHCOMPRESSION APPROACHES AT 9.6 KBPS SUFFER FROM PROBLEMS SUCH AS SENSITIVITY TO INPUT NOISE, SENSITIVITY TO CHANNEL ERROWS, INADEQUATE SPEECH QUALITY, OR SEVERE COMPUTATIONAL REQUIREMENTS. IN THIS PROPOSALWE DISCUSS AN INNOVATIVE APPROACH TO SPEECH COMPRESSION AT 9.6 KBPS THAT PROMISES TO OVERCOME MANY OF THESE PROBLEMS, RESULTING IN A PRACTICAL AND EFFECTIVE SYSTEM.
