Code excited linear prediction

Code-excited linear prediction (CELP) is a linear predictive speech coding algorithm originally proposed by Manfred R. Schroeder and Bishnu S. Atal in 1985. At the time, it provided significantly better quality than existing low bit-rate algorithms, such as residual-excited linear prediction (RELP) and linear predictive … See more The CELP algorithm is based on four main ideas: • Using the source-filter model of speech production through linear prediction (LP) (see the textbook "speech coding algorithm"); See more Before exploring the complex encoding process of CELP we introduce the decoder here. Figure 1 describes a generic CELP decoder. The excitation is produced by … See more • MPEG-4 Part 3 (CELP as an MPEG-4 Audio Object Type) • G.728 – Coding of speech at 16 kbit/s using low-delay code excited linear prediction See more The main principle behind CELP is called analysis-by-synthesis (AbS) and means that the encoding (analysis) is performed by perceptually optimizing the decoded (synthesis) signal in a closed loop. In theory, the best CELP stream would be produced by trying … See more • This article is based on a paper presented at Linux.Conf.Au • Some parts based on the Speex codec manual See more WebThis book describes several modules of the Code Excited Linear Prediction (CELP) algorithm.
