Abstract:     A method for correcting frequently misrecognized words and commands in a speech application. According to the method, when a need for correcting a frequently misrecognized word/command spoken by a user is detected, a recording is made of the misrecognized word/command in isolation. Subsequently, an in-isolation base form for the misrecognized word/command is established from the in-isolation recording. The in-isolation base form is then saved and the misrecognized word/command in recorded in context. Next, an in-context base form is established for the misrecognized word/command from the context recording and a comparison is made between the in-isolation and in-context base forms. The in-context base form is saved only if the in-isolation and in-context base forms are markedly different from one another. A sentence is displayed using the frequently misrecognized word/command in context and the user is prompted to speak the sentence. The sentence is then recognized using the speech application and the user is prompted to confirm whether or not the frequently misrecognized word/command was properly recognized. The method is terminated if the frequently misrecognized word/command was properly recognized.
