Abstract :
This paper proposes a novel speech codec named the Chinese RPE-LTP (CRPE-LTP), which exploits some of the unique characteristics of Mandarin in speech in order to improve speech quality, for Mandarin speakers. Although the codec is based on the proven principles of the GSM06.10 RPE-LTP coder; its performance is better than that of GSM for coding Mandarin speech, and is designed to at least match GSM performance for coding English speech
