  • Distributed speech system with buffer flushing on barge-in
    Patent number: 6947895
    Abstract: A distributed automatic speech recognition and text to speech system has components separated by a network. The components may be a voice interface device with jitter buffer, a voice browser and a text to speech engine. A barge-in detection feature may reside in any one of these components, to implement kill on barge in. The system, softwares and methods of the invention operate to flush the jitter buffer of the voice interface device when a barge-in is detected. Any packets that had been received are therefore not played out.

  • Devices, methods and softwares for telecommunication service provider to receive fax on behalf of subscriber on voice telephone line
    Patent number: 6735289
    Abstract: A routing switch made according to the invention is controlled by a Telephone Service Provider (“TSP”). Voice telephone calls of a subscriber with the new service are routed through the routing switch. To establish a telephone connection, the routing switch conferences two voice data paths, one of which leads to the subscriber. The routing switch further monitors the other incoming path, to detect whether a fax incoming tone appears. If it does, it unconferences the paths, and redirects the subsequent incoming fax signals to a fax receive utility. A fax is generated from the fax signals, for sending to the subscriber in a different way, e.g. as email attachment to a prearranged email address of the subscriber.
