Thank you for the report. Unfortunately that would not be a trivial problem to fix, it will take a week or so.

Please use MLLR adaptation for PTM models.

Okay. Just wanted to let you know.

How can i tell if i'm using a PTM model? Have the one that came with Sirius.

I also tried the MLLR adaptation from the tutorial. My accuracy went down by a few percent. Do people usually get better results from the tutorial?

It has a line -model ptm in feat.params. Our latest models are PTM

Yes, you should not expect a lot from MLLR and actually from MAP too. There are many factors which affect accuracy and acoustic model is just one of them. There are things like language model which also should fit, the dictionary and so on.

For accuracy debugging it is recommended to share test set of the audios you want to recognize.

How can I share my test set? I just recorded the phrases that were recommended in the tutorial.

Thanks

Thanks! I'll try it.
