Hello,

currently I am trying to launch some experiments for system combination by using several HTK recognizers/models.

I chose Recognition Output Voting Error Reduction (ROVER) for the combination system, however, it seems that I should firstly deal with the compatibility between HTK and ROVER:

1: when using ROVER script from NIST, it only supports CTM format input, but HTK offers MLF format.

I tried to convert MLF to CTM file, then one problem is about the 'Confidence Score', since MLF only shows Log-likelihood score.

are there some nice/elegant ways to do this conversion?

2: even though I gave random 'Confidence Score' to CTM file, ROVER did not create the output without any error message, which really drove me crazy.

can anyone give me some hints or examples to combine ROVER with HTK enginer????

thanks in advance ~

Hi,

Any luck with this? I'm interested in using ROVER for a project but can't find a link to any software. Could you provide a link if you have one?
