How to get a list of ALL voices on iOS 9?

问题

The standard way to get a list of 'all' AVSpeechSynthesisVoice objects, is to ask for it:

[AVSpeechSynthesisVoice speechVoices]

However, this only shows a unique default voice per language-region pair. e.g. for en-US:

"Language: en-US, Name: Samantha, Quality: Default",

If I look in the Settings app under General → Accessibility → Speech → Voices → English I see that I have 'Siri Female (Enhanced)' selected, but that voice is not selectable from code. The full list is

So the big question is: how do I select e.g. Alex or Siri Female as a voice from code?

Background

AVSpeechSynthesisVoice documentation page.
Languages for the voices should be specified in BCP-47 format. See below for the available voices, (and what their corresponding BCP-47 language codes mean).

As Axello comments below, this evidently does not include the en-AU male voice that is available in the iPhone preferences, "Lee". It would seem that he is not currently available through this API. Perhaps he will be added in time, but given that the available voices don't look like they've changed since 30th December 2015, I wouldn't hold my breath for it.

Setup

import AVFoundation

let utterance : AVSpeechUtterance = AVSpeechUtterance(string: "String to be read out.")
let voiceToUse: AVSpeechSynthesisVoice? = AVSpeechSynthesisVoice(language: "en-US")
utterance.voice = voiceToUse! // Set voice by BCP-47 language code.
AVSpeechSynthesizer().speak(utterance) // Note: Won't be heard in Swift Playground.

Answer

We can select Alex's voice directly, using AVSpeechSynthesisVoice(identifier: AVSpeechSynthesisVoiceIdentifierAlex), but oddly the only identifier that Apple have provided to date is for Alex. 🤷

For any other voices (see the above list again for the voice names), use the following code:

// From https://www.ikiapps.com/tips/2015/12/30/setting-voice-for-tts-in-ios
var voiceToUse: AVSpeechSynthesisVoice?
for voice in AVSpeechSynthesisVoice.speechVoices() {
    if #available(iOS 9.0, *) {
        if voice.name == "Karen" {
            voiceToUse = voice
        }
    } 
}

(This could be done more elegantly using filter() than a loop, but I'm not familiar with the syntax in Swift, so refer here if interested, or leave a comment if you know how to write it).

As for the voices labelled 'Siri', I have no idea. Maybe they're unrelated to AVSpeechSynthesisVoice? Comments welcomed if you know the deal behind them.

Following up on Jamie answer (now iOS 11.3 I believe also works with earlier versions):

for the other voices the identifier is structured as "com.apple.ttsbundle.Kanya-compact"

You can get those that are available by:

let voices = AVSpeechSynthesisVoice.speechVoices()
for voice in voices {
    print (voice.identifier + " " + s.language + " " + s.name)
}

and set the voice by either identifier or language.

//set utterance first!
speechUtter = AVSpeechUtterance(string:"أتمنى لك نهارا سعيد")

speechUtter.voice = AVSpeechSynthesisVoice(identifier: "com.apple.ttsbundle.Maged-compact")

speechUtter.voice = AVSpeechSynthesisVoice(language: "ar-SA")

You can use this simple command print(AVSpeechSynthesisVoice.speechVoices())
