If it makes a difference, my app is free and I made it because I need to use a text to speech app due to a disease. I learned to code because I needed this app. I usually see about 1500 uses of my app weekly, so others find it helpful.
On iOS 9 I dont have this problem, but ever sice Beta 1 of iOS 10 I do. In my app, the user can select from multiple languages and voices. The problem is only present when the English Alex voice is selected. If I select the Alex voice as my text to speech voice, just prior to saying the desired text, with the default Siri voice, it will say, "S L N C Twenty" and then in the Alex voice the text. This problem occurs with the existing iOS 9 build from Xcode 7 and a new build from the beta of Xcode 8. I have no warnings or errors in Xcode when I build my app.
The code is really simple and not much to it. I get the text from the user and the language/voice they select and just tell the synthesizer to play the phrase.
BTW, I use Objective C.
[self.synthesizer speakUtterance:self.utterance];I dont know if this is a bug or I need to change something in my code. I'm not sure what I can provide here to help.
Any ideas or comments will be appreciated.
