Speak in a meeting session
Sends audio / text-to-speech into a meeting session. With a Telnyx AI Assistant (or avatar) attached, the bot is a webpage-output bot: the speak audio routes through the assistant’s output page rather than the bot mic and plays once the assistant is connected — it is not refused. If that page cannot be reached, delivery fails with the 502 below, which may arrive without an error envelope, so branch on the status code before parsing a body. The assistant is designed to own the conversation, so prefer letting it speak or use send_chat.
