What are the BCP-47 voice codes available for iOS 7 AVSpeechSynthesisVoice?

Question

Today I'm very exited about the speech synthesis function is available in iOS7.

I want to select the male voice(default in OSX, called alex).

I don't know what's the BCP-47 code for him, and BTW how to get the full list of all voice code

Hwu

do you know if it's possible to add custom voices or where the models for the standard voices are stored in the file system? wondering if there's a way to hack custom voices. – Stiff

Answer 1

Here's how to get the BCP-47 codes of the available voices:

for (AVSpeechSynthesisVoice *voice in [AVSpeechSynthesisVoice speechVoices]) {
    NSLog(@"%@", voice.language);
}

Alex's locale is "English - United States" (en-US), as you can see in the Dictation & Speech control panel on OS X. (Click "Customize..." in the "System Voice" drop down.)
