OpenAI Realtime voice

Use this skill when the deliverable is a live spoken interaction: a browser voice assistant, phone-like agent, low-latency speech-to-speech support flow, guided interview, tutoring conversation, live kiosk, or realtime voice UI that listens, reasons, speaks, interrupts, and may call tools.

Do not use this skill for batch speech-to-text, offline TTS, voiceover generation, audio editing, dubbing, music, or file-based audio tasks. Those belong to the separate OpenAI audio/request APIs or other speech/audio skills. The boundary is simple: if a persistent realtime session and turn-taking behavior are part of the product, use this skill; if the job is "turn this file/text into text/audio," do not.
