I am looking for speech recognition packages. Someone can help-me with suggestions.

This is complex problem, it is required that applications are all the time listening and processing the information. This is not the core of my work but i need something that translates voice to text.

I have found ( and which uses pocketsphinx, but from what I have seen is not accurate and is required to build a dictionary of words.

Another solution is using the google framework (, but it is required internet connection and can take more the 3 seconds to get an answer.

Another option is use Julian ( from video looks great.

The Hark seems to be powerful but they are using multiples microphones for localization also. (,

I need something light then HARK and more efficient then pocketsphinx. I think that I will start with HARK. Can you give-me others suggestions?

From my point of view PocketSphinx is a powerfull tool for Speech Recognition. However, it need some tuning to get the most of it. Also, HARK is a good think, I do not like the way the implemented but are good algorithms for localisation and separation in quiet environments.

The most important here, is that you do not need to choose between HARK and Sphinx. HARK is a signal processing toollkit for source localisation and separation and Sphinx is a speech recognition software. However, it is very very likely that to combine them you will need to retrain or adapt the acoustic models.
