ABSTRACT:
The present invention comprises speaker-independent, continuous speech, multilingual, multi-dialect, Automatic Speech Recognition (ASR) technology. In particular, the present application integrates the ASR technology into call control technology such that it will identify key words in two ways. First, it will "Listen" to live conversations of any or all telephone lines controlled by the call control system. Second, it will "Listen" to recorded conversations of any or all voice recorder channels so that previously recorded telephone conversations can be quickly scanned to find key words or phrases spoken in the past. The unique aspect of this application is that it is being applied to the corrections industry for the purpose of spotting key words or phrases for investigative purposes or inmate control purposes which then can alert or trigger remedial action.
