Abstract

In many scenarios, speaker verification systems can be given a single-channel audio with recordings of multiple speakers. To perform accurate speaker verification, a system can isolate the speech of a speaker. In one embodiment, a method, and corresponding system, of speaker verification includes extracting a target speaker's speech, using a known speaker voiceprint, from an audio recording that includes the target speaker's speech and the known speaker's speech. The known speaker voiceprint can correspond to the known speaker. Extracting the target speaker's speech can include determining portions of the audio recording where the known speaker voiceprint matches the known speaker's speech above a particular threshold, and extracting the target speaker's speech from other portions of the audio recording. In this manner, speaker verification is performed on the target speaker's speech without interference from the known speaker's speech and allows for a more accurate verification.
