The Sphinx-4 team has released 1.0 beta2 of Sphinx-4, which is a state-of-the-art, speaker-independent, continuous speech recognition system written entirely in the Java programming language.

New features and improvements include:

  • new much cleaner and more robust configuration system
  • refactored to make use of java5 language features
  • new API to setup speech recognizers without any xml
  • improved feature extraction (better voice activity detection, many bug-fixes)
  • Cleaned up some of the core APIs
  • 'include' and 'extends' for configuration files
  • better JavaSound support
  • fully qualified grammar names in JSGF (Roger Toenz) support for dictionary addenda in the FastDictionary (Gregg Liming)
  • added batch tools for measuring performance on NIST corpus with CTL files
  • many performance and stability improvements

Oh, sweet! I still use Sphinx 4 when I need to specify a lot of configuration options. I will have to check this out.
