Speak Diarization

[Rojin Babayan]

Hi,

I'm trying to cluster (Speacker Diarizzation) the speaker of a wave file Using LIUM. The file is a discussion between two people, but the output segmentation file has more that 2 cluster. I tried to limit number of cluster to 2 cluster using "--cMinimumOfCluster " command, unfortunately it doesn't work. Could anyone please help me on this issue?

Thank you,
Rojin

You need to play with c parameter in the last stage (CLR clustering). You can try values like 1.2 and 2.0
