Abstract

The coder proposed in this paper falls in the class of segmental vocoders known as phonetic vocoders. Speaker recognisability is one of the main problems faced by vocoders at the lowest bit rates, given the need to reduce speaker specific information. Hence, phonetic vocoders are very suitable to speaker dependent coding, and can achieve bit rates as low as 250 bit/s. For speaker independent coding a speaker adaptation methodology is adopted, although resulting in higher bit rates to transmit the speaker specific information. In order to further reduce the corresponding bit rate, a new method is proposed that explores the intra-speaker correlation for the same phone.

语音编码环境下的说话人适应

本文提出的编码器属于分段声码器，即语音声码器。考虑到需要减少说话人的特定信息，在最低比特率下，说话人的识别是声编码器面临的主要问题之一。因此，语音声编码器非常适合于依赖于说话人的编码，并且可以实现低至250比特/秒的比特率。对于独立于说话人的编码，采用了说话人自适应方法，尽管会产生更高的比特率来传输说话人特定的信息。为了进一步降低相应的比特率，提出了一种新的方法来探索同一电话的说话人之间的相关性。
