A METHOD AND DEVICE FOR ACTIVATING A VOICE-CONTROLLED FUNCTION IN A MULTI-STATION NETWORK THROUGH USING BOTH SPEAKER-DEPENDENT AND SPEAKER-INDEPENDENT SPEECH RECOGNITION

摘要

A voice-controlled multi-station network has both speaker-dependent and speaker-independent speech recognition. Conditionally to recognizing items of an applicable vocabulary, the network executes a particular function. The method receives a call from a particular origin and executes speaker-independent speech recognition on the call. In an improvement procedure, in case of successful determination of what has been said, a template associated to the recognized speech items is stored and assigned to the origin. Next, speaker-dependent recognition is applied if feasible, for speech received from the same origin, using one or more templates associated to that station. Further, a fallback procedure to speaker-independent recognition is maintained for any particular station in order to cater for failure of the speaker-dependent recognition, whilst allowing reverting to the improvement procedure.
