Speech Diarisation
- Who speaks when?
- Split stream into homogenous segments for identity
- Structure stream into speaker turns
- Provide speaker identity
- Combination of
- Speaker segmentation
- Speaker changes in stream
- Speaker clustering
- Grouping segments together on basis of characteristics
- Speaker segmentation
- Gaussian mixture model
- HMM
- Bottom-up
- More popular
- Succession of clusters
- Merge redundant clusters
- Remaining belong to speakers
- Top-down
- Single cluster
- Iteratively split until speaker clusters
