OpenAI Voice (TTS)
OpenAI's TTS API and ChatGPT voice mode backbone
Part of this entry was LLM-drafted and is being polished.
OpenAI Voice / TTS — both the consumer-facing ChatGPT voice mode and the developer API. Voices are natural and emotive. Available via gpt-4o-mini-tts and other model variants. Pay per character of audio generated.
Editor's verdict
Right pick for products embedded in ChatGPT-style conversational UX — same model that ships ChatGPT voice. Quality is competitive with ElevenLabs on natural conversational tone. Less voice variety than ElevenLabs (no clone-your-own); pick OpenAI for product UX, ElevenLabs for content production.
