Google Speech Recognition

• Cromium hack by Mike Putz results in a general perl+post approach, others made it work for PHP and Java
  • Cromium speech code
• Android RecognizerIntent Sample VoiceRecognition.java Works great, but only for short speech samples (until user pauses). No GUI-free/eyes-free access yet. There are feature requests for it on the Android Google Code issue tracker.
  • Android Source on GitHub

Sphinx

• http://cmusphinx.sourceforge.net/

 CMUSphinx is a speaker-independent large vocabulary continuous speech recognizer released under BSD style license. It is also a collection of open source tools and resources that allows researchers and developers to build speech recognition systems.

Language independent phonetic transcription

• Our goal is to support a bit of bootstrapping, even for non-standard languages so that experiments on any language provide at least a bit of audio analysis.

Audio Chunking based on Silence

• The MARF project has some libraries for audio analysis. Not sure how complete and which goals have been realized yet.

 MARF is an open-source research platform and a collection of voice/sound/speech/text and natural language processing (NLP) algorithms written in Java and arranged into a modular and extensible framework facilitating addition of new algorithms.
