How to stop AVSpeechSynthesizer playback in the middle?
avspeechsynthesizer, ios, ios7, iphone, text-to-speech
Solution
Looking at the Documentation for AVSpeechSynthesizer, you need to call `-[AVSpeechSynthesizer pauseSpeakingAtBoundary:]` to stop speaking, and, then `-[AVSpeechSynthesizer continueSpeaking]` to continue speaking again afterwards.
You can choose to pause speaking right away (`AVSpeechBoundaryImmediate`), or, at the end of the current word (`AVSpeechBoundaryWord`).
Problem
I am using AVSpeechSynthesizer for text-to-speech in my app. Is it possible to stop the playback in the middle, e.g. if the user hits a stop button?
