The new iPhone 3GS has support for voice commands, stuff like "call Bill" or "play music by the strokes" and whatnot. I was looking through the iPhone SDK, but I cannot find any references to this capability. All of the search keywords I choose seem to only find the new voice chat functionality. Does anyone know whether Apple has added voice command APIs to the SDK, or whether it's yet another forbidden API? If it does exist, could someone point a particular class out to me? iphone iphone-sdk-3.0 share | edit asked Jul 13 '09 at 19:24 CaptainAwesomePants 4,672 5 26 54 87% accept rate

1   What is the voice chat capability? Is there an API hook for TTS? I've been looking for that. –  Xcoder Jul 13 '09 at 19:28 2   Apparently there's not (other than the accessibility stuff). The voice chat stuff is new. It's specifically for allowing two iPhone users to speak with each other over a data stream. It's designed for use in games. –  CaptainAwesomePants Jul 13 '09 at 20:58 feedback

Voice recognition is only available through the Voice control app, and text to speech is only available through the accessibility APIs when accessibility is turned on. share | edit answered Jul 13 '09 at 19:33 Louis Gerbarg 25.3k 4 46 68
	Is this still current as of 2011? –  FreshCode May 15 '11 at 20:37 feedback

It is a open sourcelarge vocabulary, speaker-independent continuous speech recognitionengine. Chech the README to see how to set up in XCode. share | edit edited Apr 19 '10 at 10:16 answered Apr 18 '10 at 21:44 clyfe 10.5k 1 22 52
