Abstract:
1. A method for generating a speaker model for use in distinguishing an individual speaker of interest as different from other speakers, the method comprising: extracting a plurality of frame-level acoustic features from utterances of the speaker of interest and from utterances of other speakers; performing speech recognition processing on the one or more frame-level acoustic features, wherein the speech recognition processing assigns a value to each of the one or more frame-level acoustic features; defining one or more regions within the utterances in accordance with the value assigned to each of the one or more frame-level acoustic features; modeling one or more speech features within each of the one or more regions; based on the modeling, assigning a performance measure to one or more of the extracted features, wherein the performance measure represents a strength with which the one or more extracted features distinguishes the speaker of interest from the other speakers; and based at least in part on the performance measure, creating a speaker model for the speaker of interest.
