It seems AVSpeechSynthesisVoice.speechVoices doesn’t offer Siri as voice.

Using text selection/accessibility offers Siri to speak, but we can’t replicate this using AVSpeechSynthesizer, as the Siri voice isn’t offered or returned.

Steps to Reproduce:
Compare text selection -> Speak between and PDF text selection. We miss API to offer native selection, so we manage this ourselves, and have to use custom Speak logic, and the result is worse than what the System offers here.

Expected Results:
Siri should be part of AVSpeechSynthesisVoice.speechVoices and preferred over compact/enhanced voices. A new quality setting “almostHuman” could indicate the quality increase over enhanced. Siri’s new voice is so good.

Actual Results:
Old voice, downgrade over what people are used to from Siri now.
