Pocketsphinx Is A Perfect Fit For Mobile

Pocketsphinx is going to win on mobile platforms. Right now there is no alternative to using it because of performance, accuracy and flexibility. Using pretrained US English acoustic models one can get amazing results.

That was proved once again by amazing Nightingale Browser Project. Check this video how it works

If you like it, feel free to contribute to the project. Checkout source from Gitorious http://gitorious.org/nightingale, clone, send patches, report bugs!

And, to not make you confused. Pocketsphinx is not only for mobile. You can perfectly use it in desktop applications, even in large scalable application. It's accuracy is the best we can suggest you right now!

PocketSphinx 0.6.1 release

This is a bugfix release, addressing a number of important issues in the 0.6 release. Specifically:

  • The GStreamer plugin was broken with old versions of GStreamer (such as the one shipped on Nokia Internet Tablets) which did not accept "BSD" as a valid license type.
  • Runtime performance of the statistical LM based decoder was significantly worse than 0.5 when not using phoneme lookahead.  It is now about 10% faster and also uses less memory.
  • The FSG decoder now consumes drastically less memory and CPU power.  (It is still not as good as it should be, but no longer completely embarrassing)
  • The Python modules were undocumented.  Docstrings compatible with epydoc have been added.
  • Raw audio logging (-rawlogdir) was broken.
  • Adding new words works properly, including words with unknown triphones (which never worked before).
  • The SphinxBase Python module can now use class-based language models.
  • The pitch estimation utility (sphinx_pitch) now builds properly on Win32.
  • Some problems with the N-Gram iterator API have been fixed.
  • Bestpath search has been fixed to handle recognition failure gracefully.

Source code is available for download on SourceForge.  Binary packages for Ubuntu will be updated shortly.

CMUSphinx Participates in Free Software Ecosystem

Over the years CMUSphinx become more and more popular. You probably would be interested to know that all last three month CMUSphinx gets into 25 most active projects on SourceForge. And that's not suprising.

A set of new interesting projects are started nowdays using CMUSphinx, to mention a few for example there is Vedics, a desktop control system or OpenCast project, an e-learning platorm. Others are listed in our wiki.

But we certainly need more. If you've done your term project with CMUSphinx, don't stop on that. Develop a new featured application!
