Abstract
Techniques related to speaker recognition are discussed. Such techniques include determining context aware confidence values formed of false accept and false reject rates determined by using adaptively updated acoustic environment score distributions matched to current score distributions.
Claims25
A computer-implemented method of speaker recognition comprising:
- determining at least one current speaker score based on received audio input;
- predicting the context of the audio input comprising finding a match between data of the audio input and pre-stored context audio data associated with an acoustic environment context of a plurality of acoustic environment contexts, wherein the individual contexts are associated with a speaker score distribution and context parameters characterizing the speaker score distribution;
- and
- generating at least one context aware confidence indicator comprising a false accept rate-related value or a false reject rate-related value or both based, at least in part, on the current speaker score and the context parameters.

A system for performing speaker recognition comprising:
- a memory configured to store a received audio input;
- and
- a digital signal processor coupled to the memory and to operate by:
- determining at least one current speaker score based on received audio input;
- predicting the context of the audio input comprising finding a match between data of the audio input and pre-stored context audio data associated with an acoustic environment context of a plurality of acoustic environment contexts, wherein the individual contexts are associated with a speaker score distribution and context parameters characterizing the speaker score distribution;
- and
- generating at least one context aware confidence indicator comprising a false accept rate-related value or a false reject rate-related value or both based, at least in part, on the current speaker score and the context parameters.

At least one machine readable medium comprising a plurality of instructions that, in response to being executed on a computing device, cause the computing device to operate by:
- determining at least one current speaker score based on received audio input;
- predicting the context of the audio input comprising finding a match between data of the audio input and pre-stored context audio data associated with an acoustic environment context of a plurality of acoustic environment contexts, wherein the individual contexts are associated with a speaker score distribution and context parameters characterizing the speaker score distribution;
- and
- generating at least one context aware confidence indicator comprising a false accept rate-related value or a false reject rate-related value or both based, at least in part, on the current speaker score and the context parameters.
