摘要：
A GUI-based software tool that provides a framework for evaluation of different speech coding algorithms is presented. The tool is designed to measure the susceptibility of speech coding algorithms to errors added on the encoded bit-stream during transmission. In particular, the errors can be added individually to the parameters that comprise the encoded bit-stream. This enables a designer of a speech codec to evaluate its performance under adverse or impaired channel conditions. The tool is universally applicable to different speech coding algorithms, by means of a user-defined bit-stream definition file. In fact, the tool has been used in the past to evaluate a number of standardized speech coding algorithms. This paper describes the features of the software. In addition, the paper presents sample results generated by this tool during a study of the ETSI GSM Enhanced Full Rate algorithm.
