How to stop AVSpeechSynthesizer playback in the middle?

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?

Answer Source

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).
