Hi, I recently installed sphinx3 on my pc and was able to setup my own recognition system. I could also adapt the RM1 database in a supervised way to my voice and found the recognition to improve.

When I started off with supervised adaptation, I came across this function in sphinxtrain( bw ) which carries out 1 iteration of the forward-backward algoritm. When i do not specify any transcript file(i.e. unsupervised), the function just dies when i call it in command line. It seems to be working fine when it(transcript file) is specified.

So, does sphinx3 offer unsupervised adaptation features? If yes, how do I go about doing it? bw and mllr dont seem to be working..atleast i dont seem to be able to figure out how to make them work. pl. post on suggestions and methods to do unsupervised speaker adaptation in sphinx3.

Thanks.

Cheers
