Dictation Support in Text Input Views
On supported devices, iOS automatically inserts recognized phrases into the current text view when the user has chosen dictation input. The new
UIDictationPhrase class (declared in
UITextInput.h) provides you with a string representing a phrase that a user has dictated. In the case of ambiguous dictation results, the new class provides an array containing alternative strings. New methods in the
UITextInput protocol allow your app to respond to the completion of dictation.
