Voice recognition is different than speech to text; different problem. I think if we change the title to add "in iOS" it would be a more unique question. — Stephano, Nov 05 '10 at 15:34
@Stephano - However, the questions that are actually asked there do look for speech-to-text capabilities, so the answers are relevant to this one. — Brad Larson, Nov 11 '10 at 13:52

Here is the Cocoa class for speech recognition.

Also, O'Reilly has some interesting things to say about working with speech on Mac OS 10.

Finally, there was a similar post here:

iPhone App › Add voice recognition?

As far as libraries go, I'm not sure you will find many specifically for iOS. However, check out libraries like CMU Sphinx and Julius. This will at least get you started in looking at how speech is it produced and perceived.

Good luck with your project. That sounds like a really fun idea!

I don't believe speech recognition is available in iOS. I think you're right to recommend CMU Sphinx-- they have an iOS library for voice commands and speech synthesis. – Justin Nov 06 '10 at 14:37
