Abstract
A reliable method for terminating a telephone call is disclosed using a specific sequence of steps performed by the hands-free control system. The invention requires that the call terminating command sequence be recognized as: (1) two separate speech utterances (e.g., TERMINATE and CONVERSATION); (2) in proper sequence (e.g., TERMINATE first, then CONVERSATION); (3) with a maximum pause time interval between the end of the first utterance and the start of the second utterance (e.g., 300 milliseconds); and (4) which meet predefined speech recognition matching criteria. Moreover, the present invention provides the user with a procedure to continue the telephone call in progress should the speech recognizer false, or if the user did not intend to speak the proper command. As a result, present invention enables a user to disconnect a telephone call by voice command with a high degree of reliability, even under high ambient noise conditions.
