Abstract
Disclosed is a speaker diarization process for determining which speaker is speaking at what time during the course of a conversation. The entire process can be most easily described in five main parts: Segmentation where speech/non-speech decisions are made; frame feature extraction where useful information is obtained from the frames; segment modeling where the information from the frame feature extraction is combined with segment start and end time information to create segment specific features; speaker decisions when the segments are clustered to create speaker models; and corrections where frame level corrections are applied to the information extracted.
Claims15
A method for speaker diarization, when implemented on a computer system, causes the computer system to perform the following steps:
- acquiring an audio data;
- segmenting the audio data into a plurality of segments;
- segmenting the plurality of segments into a plurality of frames;
- extracting information from the frames and labeling the frames with a plurality of frame features;
- prewhitening the frame features;
- calculating a plurality of segment models;
- determining a plurality of speaker decisions;
- and
- correcting the speaker labels of the segments.
