Abstract
A method and system for using conversational biometrics and speaker identification and/or verification to filter voice streams during mixed mode communication. The method includes receiving an audio stream of a communication between participants. Additionally, the method includes filtering the audio stream of the communication into separate audio streams, one for each of the participants. Each of the separate audio streams contains portions of the communication attributable to a respective participant. Furthermore, the method includes outputting the separate audio streams to a storage system.
Claims20
A method implemented in a computing system, the method comprising:
- removing background noise from a communication and performing normalization of the communication to enhance accuracy of the communication;
- extracting a plurality of audio streams from the enhanced communication, wherein:
- the plurality of audio streams correspond, respectively, to a plurality of participants in the enhanced communication, and
- the plurality of audio streams contain portions of the enhanced communication corresponding, respectively, to the plurality of participants;
- and
- matching one or more of the portions of the enhanced communication in the plurality of audio streams to voice prints by comparing the plurality of audio streams to only a plurality of the voice prints corresponding to identified participants within the enhanced communication and by utilizing physiological traits and behavioral traits found in speech of the identified participants;
- adapting a speaker model of the voice prints after successfully matching the one or more of the portions of the enhanced communication in the plurality of audio streams to the voice prints, wherein adapting the speaker model includes capturing long-term voice changes of the identified participants in the voice prints used for the matching.
