Abstract :
A low bit rate coding speech algorithm is introduced in this paper. This algorithm can make the bit rate lower than MBE under good speech quality, and its bit rate can reach to 2kbps. Meanwhile we discuss the chip design based on this algorithm, analyzing the process of designing speech chip using Motorola C_CORE. Finally we describe the principle of this coding algorithm and explain the difference between this algorithm with others.
