On Mac OS 11, in Accessibility → Spoken Content → System Voices: , there are 4 Siri Voice options (English US). However when I get a list a voices on the computer those 4 voices don’t come up.
Also if I go to System>Library>SpeechBase>Voices there are some voices there that don’t come up in the list of voices. I looked at the plist for AaronCompact.SpeechVoice, which doesn’t appear in the list of voices, and noticed a line that says “com.apple.speech.synthesis.voice.custom.siri.aron.compact”
Now compared to one of the voices that appear in the list, for example Samantha, the line is slightly different - “com.apple.speech.synthesis.voice.samantha.compact” . No “custom.siri”.
Is it possible to set the voice in “say -v” to one of the Siri voices or one of the other voices that don’t appear in. the list or are the reserved just fro Apple to use?
