One of the most recent advances in the field of computer technology is the area of Automatic Speech Recognition(ASR). There have been many attempts to harness ASR to help in English speaking testing. In this paper I attempt to design such a program which will facilitate English speaking Testing. This program concerns elementary school level because there are more demands for it here. For this purpose I developed a prototype testing tool using Talking Max as an authoring program. First I analyzed the function of Talking Max. Then I constructed new algorithm for the discourse model of ASR. I also drew the communicative functions in the contents of testing units to design testing scripts. I submitted this prototype to a pilot test which includes computer simulations. Finally, I verified the goodness of this prototype as a testing tool by estimating testing validity, reliability and practicability. The result of the study indicated that the testing tool with powerful ASR functions enables us to measure student’s speaking ability effectively, especially for the formative testing. It is also shown that the prototype also has considerable accuracy in measuring student’s speaking ability.
