Abstract: A communication station and communication method for effectively multiplexing data into a combined data stream by adding a special header to the combined data packet. The bit positions of this special header indicate the presence of data packets in a data stream in a combined data packer. The combined data packet is transmitted from the first to the second communication station through a first communication channel. Changes in the data streams can be communicated to the receiving communication station through a second communication channel, so that the second communication station can restore relations between data streams and recreate stripped headers.

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.
