Diarization of the Language Consulting Center Telephone Calls
Original language description
In this paper, we describe a diarization of the archive data from the project “Access to a Linguistically Structured Database of Enquiries from the Language Consulting Center”. This project is attempting to provide improved access to the large archives of the Czech language of mainly telephone conversations collected continuously by The Language Consulting Center. One part of this archives contains mono recordings, where the data of the client and the language counsellor are mixed in one channel. In our proposed approach to a diarization, we used the information about the identity of the language counsellor acquired from the text transcription on the beginning of the conversation. For the initial stage of the diarization, our system based on clustering the x-vectors was adopted. The resegmentation step is used for refining the boundaries of speaker changes by the pre-trained Gaussian mixture model of the counsellor. Because of the uniqueness of our data, we compared our results with the Kaldi diarization as the baseline system.
