AI Voice — OpenAI: GPT Audio Mini — FAQ

OpenAI: GPT Audio Mini supports a wide range of languages. The exact list depends on the engine; the form on this page accepts any text and the engine will render in its supported languages. See /voice/ for the full multi-engine picker if you need a specific language.

Most engines render neutral-American English by default and a region-appropriate accent for non-English languages. Premium engines may expose accent variants — paste a sample to compare.

SSML support varies by engine. Pause, prosody, and emphasis tags are honored on most premium engines and on a few self-hosted ones. Plain text always works — no markup required.

Streaming TTS is available on premium engines via the /v1/tts/ API endpoint with stream=true. The web UI on this page returns the full clip once rendering finishes.

OpenAI: GPT Audio Mini is a premium TTS engine. Cost scales with character count — typically ~30 tokens per character. $1 buys 750,000 tokens, so a $5 pack covers tens of thousands of characters.

Up to 5,000 characters per request on the web UI. For longer pieces (audiobooks, full chapters), use /voice/audiobook/ which chunks and stitches automatically, or call the API in a loop.

Yes — POST a list of strings to /v1/tts/batch/, or use the workspace UI at /workspace/ to chain TTS into a longer pipeline (e.g., translate → speak → stitch).

Yes — POST text to /v1/tts/ with model="OpenAI: GPT Audio Mini" (or the slug on this page). Returns WAV or MP3. See /api/ for full reference + SDK snippets.

This page is text-to-speech, not voice cloning — the voice is the engine's default. For voice cloning (uploading a reference audio), see /voice/clone/, which requires you to either own the voice rights or have explicit written consent.

Self-hosted engines run on Free.ai-owned GPUs; nothing leaves our servers. Premium engines pass text to upstream model providers under our DPA. We do not train on your inputs and do not sell data.

Yes — Free.ai grants commercial use of generated audio. The engine's underlying license (Apache 2.0, MIT, or vendor terms) is shown above and on the model reference page; in practice this means voiceovers, ads, podcasts, and apps are all in-scope.

Yes — failed jobs auto-refund to the source (daily pool or paid tokens). If a refund does not show up the same day, email contact@free.ai.
