Voice recognition is an important technique for man machine interfaces, but the accuracy degrades if a variety of communications is required. One of practical solution is to restrict the general communications into the domain specific topics dynamically. However, it is difficult to detect the specific domain from the general conversation and to adopt the language model for the specified domain effectively. This paper presents a domain specific voice recognition technique using field association knowledge that can find only the segment of utterances. Therefore, it enables us to change the domain of the language models in the real time processing. In this method, field association knowledge is used as the preprocessor of the first voice recognition stage and determines the appropriate domain in the conversation. The voice recognition of the second stage just changes the language model suggested by the first stage. The proposed approach is evaluated for 600,000 field association terms related to
