ios cannot perform text to speech conversion

Question

I am new to iOS development. I want to perform a simple text to speech conversion within app. Following is my code:

AVSpeechSynthesizer *speechSynthesizer = [[AVSpeechSynthesizer alloc]init];    
AVSpeechUtterance *utterance = [AVSpeechUtterance speechUtteranceWithString:@"Test text to speech conversion"];    
[utterance setRate:1.1f];    
[speechSynthesizer speakUtterance:utterance];

The above code is not giving me any exception but its not working at all. I've tried multiple APIs given on GitHub but nothing worked for me. Could anybody tell me where I might be going wrong? Do I have to make any settings on device?

Answer 1

Problem sorted..!! Actually the problem was, I had "USE SIDE SWITCH TO:" option in the Settings->General set to "Mute". I set that option to "Lock Rotation" and got rid of my problem. I found a related post here discussions.apple.com/thread/5366534

It's not working because of the Mute mode of your phone. To turn 'Mute On' in iOS 7, you have to follow the following steps:

• Go to your Setting option
• Go to Accessibility
• Go to AssistiveTouch
• Turn on AssistiveTouch option from the switch button
• Then a Moving Assistive icon, will appear on you device screen.
• Touch on it to expand with more options
• From there select Device and Touch Un mute option.

Now run the project and hope it will work.

P.S: (In iOS 8.0 this code wouldn't work, because for an unexpected bug, from iOS8.1 they remove it and it is now working perfectly) Hope it works. :)
