iPhone speech recognition API? [duplicate]

Answer 1

The SDK does not support either voice recognition or text to speech. 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.

Answer 2

One could try to bundle poketsphinx speech recognition library from the CMU Sphinx project. It is a open source large vocabulary, speaker-independent continuous speech recognition engine. Chech the README to see how to set up in XCode.

Answer 3

OpenEars is a really nice Objective-C API for CMU Sphinx. Worth checking out if you want to incorporate CMU Sphinx in your app.
