Abstract: 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 item 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, while allowing reverting to the improvement procedure.

Abstract: A method of asynchronous duplex data communication between a pair of stations, a PABX and a telephone management system (TMS) relating to specific services to be performed by one of the two stations, the one station requesting, by means of an initialization request, a specific service and the number of times that this service is to be performed simultaneously, and the other station, depending on its capacity, allocating, by means of an initialization response, a number of times that the service can be performed simultaneously, which number is equal to or smaller than the requested number. After the number is allocated, it is possible to proceed by means of transaction messages to the actual performing of the services. These services for example apply to specific applications of a telephone system in a hotel.
