  • Patent number: 6792083
    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.

  • Patent number: 5469441
    Abstract: A digital telephone communication system, for example ISDN or ESPABX, having an exchange and a plurality of user stations, the exchange communicating with each user station by at least a signalling (D) channel and a communication (B) channel of greater bandwidth. A service station is connected to the exchange in which is stored programming information for the user stations. Each user station includes a processor in which the telephone directory number of the service station is stored. Programming information available at the service station can be obtained by the processor of a user station by calling the service station, and is transmitted from the service station over the B channel. The service station may also provide unrequested programming information to any or all of the user stations over the B channels.

  • Patent number: 5450486
    Abstract: Telecommunication systems such as PABXs are known which comprise ISDN digital linecards with a number of ISDN basic access interfaces. A telecommunication device is proposed comprising configurable ISDN digital linecards. To this end the linecards are provided with configuration means for independently configuring each ISDN basic access interface with respect to the other ISDN basic access interfaces as to mode setting and phantom power feeding to the transmission line to be coupled to the interface. The modes to be set are ISDN-NT or ISDN-TE mode. It is achieved that the PABX can be set to customer specifications without customer specific linecards having to be manufactured. Accordingly, no high manufacturing change-over costs are involved and no expensive extra documentation sets have to be drawn up, as would have been the case when many customer specific linecards would have to be manufactured.

  • Patent number: 5031207
    Abstract: A method of establishing a data link between a first terminal, which is capable of communicating in accordance with a number of different data communication standards, and a plurality of further terminals which are each capable of communicating in accordance with a single data communication standard, whilst indicators (profile indicators) are extended to the dial numbers of the further terminals in the first terminal these indicators showing according to which data communication standard a specific further terminal is operating. If such an indicator is found with the telephone number when a link to a further terminal is established, the first terminal is automatically reprogrammed for subsequent operation in accordance with the data communication standard of the further terminal.
