Openears will support free speech recognition and text-to-speech functionalities in offline mode.
They have FliteController Class Reference, which controls speech synthesis (TTS) in OpenEars.
They have done an excellent job in speech recognition area.
However, please note that it will detect only the words that you mentioned in vocabulary files.It iss good to work as offline mode to get the better performance.
@Halle: Correct me if I’m wrong.
You have a paid option, Dragon Dictation which is working as online engine.
or use VocalKit: Shim for Speech Recognition on iPhone
I would like to point out that , none of them are accurate than Siri (Siri SDK is not available yet).
