CMU Sphinx Downloads

Software

The CMU Sphinx toolkit has been around for quite some time, and has produced a large number of packages and libraries. At the moment, only these are currently being maintained:

  • PocketSphinx — recognizer library written in C.
  • SphinxTrain — acoustic model training tools

We recommend you use the current development code:

We do not maintain distribution-specific packages yet, but help to update them is truly appreciated. Some GNU/Linux distributions already include CMUSphinx packages.

Models

CMUSphinx assumes that you use the statistical models which describe language. There are many models trained for various acoustic conditions and various performance requirements. We collect the best models available at our download page. We hope you’ll be able to find the best model for your language there:

(note: we will be moving away from SourceForge soon).

We are also planning to use bittorrent tracker to distribute the models but we are not there yet, if you are willing to help, please contact us
