Abstract:     A voice processing system comprising a digital trunk processor 135 and a system unit 145 incorporates a local voice recognition resource 185 provided on a digital signal processing board 180, and can access a remote voice recognition resource 320 in a server 300 via a local area network 250. The system provides a barge-in facility for the recognition resource on the remote server, whereby a prompt is played out to the user, and the incoming telephony signal is fed into a voice activity detector on the digital trunk processor. Responsive to a detection of incoming voice activity, the outgoing prompt is terminated, and the incoming data is transferred over the local area network to the remote server for recognition.

First Claim:
Show all 16 claims
What is claimed is:     1. A voice processing system comprising:
  • a telephone interface unit over which telephony calls can be made and received, said telephone interface unit receiving an incoming audio signal as part of a telephone call;
  • an application program for controlling the processing of said telephony calls;
  • first means for connecting a local speech recognition resource on an adapter card to said telephone interface unit via a time division multiplex bus, for transferring said incoming audio signal from said telephone interface unit to said local speech recognition resource via a timeslot on said time division multiplex bus;
  • second means for connecting a remote speech recognition resource on a server system to said telephone interface unit via a local area network, for transferring said incoming audio signal from said telephone interface unit to said remote speech recognition resource in packets over said local area network;
  • wherein said local speech recognition resource is different from said remote speech recognition resource, the former being provided on a DSP within said voice processing system, the latter being a purely software system external to the voice processing system;
  • said voice processing system further comprising a voice technology subsystem providing an application interface for said application program to access said local or remote speech recognition resource to process said incoming audio signal to determine recognised text corresponding to said incoming audio signal, said application interface rendering it transparent to the application program whether the incoming audio signal is transferred from the telephone interface unit to the local speech recognition resource over said time division multiplex bus or to the remote speech recognition resource over said local area network.
