ABSTRACT:
Disclosed are a method and apparatus for processing a continuous audio stream containing human speech in order to locate a particular speech-based transaction in the audio stream, applying both known speaker recognition and speech recognition techniques. Only the utterances of a particular predetermined speaker are transcribed thus providing an index and a summary of the underlying dialogue(s). In a first scenario, an incoming audio stream, e.g. a speech call from outside, is scanned in order to detect audio segments of the predetermined speaker. These audio segments are then indexed and only the indexed segments are transcribed into spoken or written language. In a second scenario, two or more speakers located in one room are using a multi-user speech recognition system (SRS). For each user there exists a different speaker model and optionally a different dictionary or vocabulary of words already known or trained by the speech or voice recognition system.
