OpenAI Text-to-Speech API

OpenAI's TTS endpoints (tts-1, tts-1-hd, gpt-4o-mini-tts) that turn text into speech in a handful of preset voices.

+ Cheap, simple and already in the SDK you probably use, with gpt-4o-mini-tts accepting instructions on tone and style.
− Only a small set of fixed voices and no voice cloning.

OpenAI Text-to-Speech API alternatives

All 5 alternatives →
1
ElevenLabs Free tier
Text-to-speech and voice cloning with the most natural-sounding voices on the market, plus dubbing and a voice isolator.

+ Voices carry emotion and pacing that still beat most competitors, and AI dubbing translates a video while keeping the speaker's voice.
− Character-based credits run out fast on long scripts, and voice cloning raises consent and misuse concerns.

WellSaid Paid
Enterprise text-to-speech with a library of consistent studio voices for training, e-learning and corporate video.
