Get Available Agent Voices
Get available agent voices.
Each voice's status is resolved against the current date. Retired voices are omitted unless their display name is passed in selected_voice, so a saved config still referencing a retired voice can render it as a locked field. A voice group holds one voice per language, so the parameter is repeatable.
