How to stop AVSpeechSynthesizer playback in the middle?

Question

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?

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).

Hello, I can't Stop on any button tapped, I want to stop it when cancel button pressed. I tried as below: if(av_speechSynthesizer.isSpeaking || av_speechSynthesizer){ do something } – Er.Shreyansh Shah Nov 05 '14 at 11:35

Instead of "pauseSpeakingAtBoundary:" use [AVSpeechSynthesizer stopSpeakingAtBoundary:AVSpeechBoundaryImmediate]; – Er.Shreyansh Shah Nov 05 '14 at 11:41

In swift:

synthesizer.stopSpeaking(at: .immediate)

or

synthesizer.stopSpeaking(at: .word)
