Definition: CELP

(Code Excited Linear Predictive) A speech compression method that achieves high compression ratios along with toll quality audio. LD-CELP (Low-Delay CELP) provides near toll quality audio by using a smaller sample size that is processed faster, resulting in lower delays. LD-CELP was developed by Dr. Raymond Chen when he was at AT&T. Chen was also involved with CELP. CELP is pronounced "kelp."
