Fish Audio's Drama 3 text-to-speech model arrives on Vercel AI Gateway
Vercel has added Fish Audio's Drama 3 to AI Gateway. The text-to-speech model, currently in preview, lets developers direct voice performances with natural-language instructions written into the script.
- Fish Audio's Drama 3 text-to-speech model is now available on Vercel AI Gateway, in preview.
- Voice delivery is directed with natural-language instructions in square brackets and tags such as <whisper> and <emphasis>.
- The model supports multi-speaker dialogue with a separate voice per character, and directions can be in a different language from the speech.
- It is offered at 80% off for 30 days, through Nov 12.
- Developers use the model name fish-audio/drama-3.
Directing speech from inside the script
According to Vercel, Drama 3 is aimed at voiceovers, character dialogue and audio storytelling. Instead of adjusting separate settings, users describe how a line should sound directly in the text.
Emotion and pacing can be described in square brackets. Sounds and pauses can be placed where they belong in the script. Selected words can also be wrapped in tags such as <whisper> and <emphasis> to change how they are delivered.
Vercel also notes that directions can be written in a different language from the spoken text. Drama 3 supports multi-speaker dialogue as well, with a separate voice for each character.
Getting started with the AI SDK
Developers call the model with the name fish-audio/drama-3. Vercel's example uses the AI SDK's experimental_generateSpeech function. The sample script passes the text [warm and reassuring] Take your time. <whisper>I am right here.</whisper>, a voice ID and an output format of mp3, then writes the returned audio to a file.
The model can also be tried in the model playground, and Vercel links to a page with model details.
Discounted pricing and what AI Gateway offers
Drama 3 is available at 80% off for 30 days, through Nov 12, according to Vercel. The source gives no regular price for the model.
AI Gateway is Vercel's unified API for calling models. Vercel says it covers tracking usage and cost, and configuring retries, failover and performance optimizations for higher-than-provider uptime. It also lists built-in custom reporting, Zero Data Retention support, budgets for API keys and routing rules.
Vercel states that AI Gateway reflects provider pricing with no markup and does not charge a platform fee on inference, including on Bring Your Own Key (BYOK) requests.
What it means for developers
For teams that already route model calls through AI Gateway, Drama 3 adds a speech option reachable with the same API and the same usage and cost tracking. Because the model is in preview, its behavior and availability may still change. The discount window runs only through Nov 12, so anyone planning to test it at the reduced rate has a limited period to do so.
