Limit number of output speakers

Hello,

Is it possible to limit number of output speaker to two ?

Thanks,
Alex.

Hi Alex,

VBx can find the number of speakers but it is not possible to force it to converge to a specific amount. You can use the hyperparameter Fb to bias the model to find less speakers (by using larger values) but the model will still have freedom to find the number of speakers that it believes there are. This approach can still lead to mistakes. Perhaps, you might be better off if you use agglomerative hierarchical clustering and set the number of clusters to 2.
You would need to change the call

VBx/VBx/vbhmm.py

Lines 145 to 146 in 7dfa3fa

    
           labels1st = fcluster(lin_mat, -(thr + args.threshold) + adjust, 
        
               criterion='distance') - 1

with maxclust if I'm not mistaken.
