PROCESS OF CODING OF PROSODY FOR CONVERSATION AT LOW DECIBELLEVELS

摘要

method of coding and decoding of speech using an encoder at a very low flow rate, comprising a step of learning to identify the "representatives" of the speech signal, and a step of codage for segmenting the speech signal, and determining the best representative "associated with each segment.the process comprises at least one step of coding decoding, at least one of the parameters of the prosody of segments identified.as the energy and / or the pitch and / or voisement and / or the length of the segments using a prosody information "best representatives".application to flows of less than 400 bits per second.
