Abstract
Speech coding is a technique that transforms speech signal of big data to digital signal of small data. This characteristic is suitable for the underwater acoustic transmission of narrowband communication. It's one of the support to underwater acoustic high speed voice communication on the source code level. This paper expounds MELP, and applies PESQ, an objective speech quality assessment, to evaluate and mark the quality of speech coding. According to the evaluation score to judge the quality of speech communication. It is suppressed that the stabile noise components in decode speech by using spectrum subtraction method. Experimental results show that it can improve the PESQ evaluation score and obtain better auditory perception.
