Abstract

Attractive improvements have been made during these days in coding speech with high quality at low bit rates and low delay. The need for low bit rate speech coding algorithms continues, supported by the ever increasing number of users to the wireless communication networks. This paper discusses the implementation details of Code Excited Linear Prediction Speech Coder at different bit rates (16Kbps, 9.6Kbps, 7Kbps, 6.8Kbps, 4.9Kbps and 4.8Kbps) and analytical evaluation of performance in terms of bit rate and quality using PRAAT software.
