Default voice when assemblyAITts() is called with no voice — a
US-accented English voice, since most agents face US callers (it was
"vera" for a while, which put a UK accent on every agent that never
chose). Pick from ASSEMBLYAI_TTS_VOICES to change it; every voice
in the catalog speaks exactly one language, so changing language
generally means changing voice too.
