Blind Diarization of Recorded Calls with Arbitrary Number of Speakers

摘要

In a method of diarization of audio data, audio data is segmented into a plurality of utterances. Each utterance is represented as an utterance model representative of a plurality of feature vectors. The utterance models are clustered. A plurality of speaker models are constructed from the clustered utterance models. A hidden Markov model is constructed of the plurality of speaker models. A sequence of identified speaker models is decoded.

1. A method of diarization of audio data, the method comprising:
segmenting audio data into a plurality of utterances; representing each utterance as an utterance model representative of a plurality of feature vectors of each utterance; clustering the utterance models; constructing a plurality of speaker models from the clustered utterance models; constructing a hidden Markov model of the plurality of speaker models; and decoding a sequence of identified speaker models that best corresponds to the utterances of the audio data.
