Is anyone else unable to use the AVSpeechSynthesizer with a voice other than "en-US"? The array that gets returned when I call AVSpeechSynthesisVoice speechVoices still returns the complete list that can be seen in iOS 7, but none of them actually work.
I tried looking through the known issues on the iOS 8 release notes, but didn't see anything about this. Hopefully this is something that will be fixed in the full version, as I have a couple apps that make use of multiple voices.
This problem appears to have been fixed in iOS 8.1.
