I covered basic manipulation of the audio hardware, but moving on from this you might be thinking about integrating speech recognition into your application. At least until Apple gets round to adding this to the official iOS SDK, the best way to do this is probably using the CMU Pocketsphinx and CMU Flite libraries. There are actually two fairly good Objective-C wrappers to the libraries, these are VocalKit and OpenEars. Of the two, at least at the time of writing, OpenEars probably has is the best documentation which may be a deciding factor if you’re not a expert in speech recognition.
