#2 CMU Sphinx

Hello again!

It’s been another two weeks of “coding for decoding” for me.

What did I manage to do since my last post?

Things look really good by now, I’m making constant progress. A very important thing I managed to implement is collecting adaptation data from a Result object. I also implemented the part that uses this data for creating the adaptation file.

I must say that after seeing in the first weeks that the algorithm which estimated the transform was working well, but reading counts from a file generated with sphinxtrain, this was the next big step, to collect counts from the result of the first decoding process. This task is the part that took me the most by now.

I also implemented a component that based on the adaptation data creates a new means file. This is equivalent to having a new adapted acoustic model that will decode better if used with audio files containing speech of the persons that adaptation was made for.


You can see my work at:

- https://github.com/bogdanpetcu/sphinx4/tree/master/sphinx4-core/src/main/java/edu/cmu/sphinx/decoder/adaptation        - adaptation package that I implemented from scratch.

- https://github.com/bogdanpetcu/sphinx4/commits/master        - here you can see all of my commits

Have a great week!

Bogdan Petcu
