macOS now has a few newly added voices that we can choose from in VoiceOver Utility > Speech. I quite like the Siri Male (United States) voice, but neither the command say nor using Automator will let me select this or any other Siri voices to use. So far I could only use the voice with the hotkey to read out loud selected text.
Is there a way to use those new voices to render text to audio files?
