Language model and Acoustic Model Speech recognition development for Malayalam using CMU Sphinx

Discussion thread for LM and AM development for Speech recognition of Malayalam uisng CMU Sphinx

Mentor : Mrs. Deepa Gopinath

Link to the current work I have done: ml-lm-am

The workflow I followed for my initial trial of the idea during my Major project:

  1. Use The Datuk corpus as the source for Malayalam corpus (
  2. Build a Phonetic dictionary using this corpus
  3. Develop unigram, digram, and trigram Statistical language model using CMU­CSLM
  4. Training phase and acoustic model development using five different people.
  5. Testing for accuracy, could only achieve roughly 60% due to time limitations for the
    project submission.

I will create a repo in gitlab under smc, please fork it and give PR’s regularly.

I think a name that non-malayalees can recognize will be a better choice

Ohh… right!

Well then normal naming like ‘ml-speech’ or something similar. Can’t get anything simple enough in my mind. :smiley:

One more doubt, Is it possible to edit the description?
There is a mistake in the hyperlink I provided for ‘ml-lm-am’ . Its supposed to be this : GitHub - sreecodeslayer/ml-am-lm-cmusphinx: This is Malayalam Speech Recognition model developed for CMUSphinx. This is now used for Google Summer Code 2016

Yes, it is possible to edit discourse posts. Just find the edit button among the tools on the bottom of the post.

##Status update:
Completed an initial build of Language Model and Acoustic Model.
Need to test accuracy and see if I can improve a bit perhaps.
