This paper investigates the influence of GSM speech coding on text independent speaker recognition performance. The three existing GSM speech coder standards were considered. The whole TIMIT database was passed through these coders, obtaining three transcoded databases. In a first experiment, it was found that the use of GSM coding degrades significantly the identification and verification performance (performance in correspondence with the perceptual speech quality of each coder). In a second experiment, the features for the speaker recognition system were calculated directly from the information available in the encoded bit stream. It was found that a low LPC order in GSM coding is responsible for most performance degradations. By extracting the features directly from the encoded bit-stream, we also managed to obtain a speaker recognition system equivalent in performance to the original one which decodes and reanalyzes speech before performing recognition.

本文调查GSM 讲话编制程序的影响对文本独立报告人认识表现。三个现有的GSM 讲话编码人标准被考虑了。整体TIMIT 数据库通过了通过这些编码人, 获得三个自动译码的数据库。在第一实验, 它被发现对GSM 编制程序的用途极大贬低证明和证明表现(表现在书信以各位编码人的感知讲话质量) 。在第二个实验, 特点为报告人识别系统被计算了直接地从有用的资料在编码位小河。它被发现低LPC 命令在GSM 编制程序负责对多数性能退化。由提取特点直接地从编码位小河, 我们并且设法获得报告人识别系统等效在表现到原始一个解码和重新分析讲话在执行认识之前。
