Abstract

The invention discloses a conference recorder with a speaker speech extracting function. The conference recorder with the speaker speech extracting function comprises a main control module, a recording and playback module, a removable storage module, an interaction and display module and a speaker speech processing module, wherein the speaker speech processing module comprises a speaker segmenting module and a speaker clustering module. The main control module transmits a conference speech stream to the speaker segmenting module, and the speaker segmenting module detects speaker changing points in the speech stream and segments the speech stream into a plurality of speech sections according to the changing points; the speaker clustering module carries out speaker clustering on the segmented speech sections through a spectral clustering method, the speech sections of the same speakers are jointed together in sequence, and thus the number of the speakers and the speech of each speaker are obtained. The conference recorder and the speech extracting method are capable of automatically extracting the speech of each speaker from the conference speech, comprehensive in function and convenient to use.

Description

technical field [0001] The invention relates to the field of audio processing, in particular to a conference recorder with a voice extraction function and a voice extraction method. Background technique [0002] The conference recorders currently on the market only have simple functions such as recording, playback, and transfer, but do not have the function of analyzing and understanding the speaker's voice content. When making meeting minutes, if the user needs to summarize and process the speech of a specific speaker, he must listen to the entire recording and manually identify whether it is the same speaker. In order to save time, there is a risk of missing useful information during fast-forward playback. Manually marking and extracting voice data is extremely inconvenient for users. [0003] Therefore, people hope that in addition to the functions of recording and playback, the conference recorder can also analyze and understand the content of the conference record. T...
