WHY VOICE DESIGN

## Your voice, your brand, every surface

Stock voices sound like everyone else. Voice Design lets you create one that sounds like you, then use it everywhere Telnyx handles speech.

* ### Designed for your brand  
Describe the voice that fits your product and generate it. Iterate on tone, accent, and energy until it sounds right. No studio, no dataset, no waiting.
* ### One voice across every channel  
Use your custom voice in AI Assistants, Call Control, IVRs, and the TTS WebSocket. Same voice ID, same quality, no re-recording.
* ### From design to live in one platform  
Create, preview, save, and deploy a voice without wiring together separate providers. The same API that generates the voice carries it into production.

FEATURES

## Built for control, not just generation

Voice Design gives you the tools to create, refine, and ship a voice that is exclusively yours.

* Minutes to a custom voice  
From a text description to a production-ready voice in under a minute. Brand-fit voice creation at the speed of a prompt.
* Iterate until it sounds right  
Generate as many samples as you need. Refine the description, try again. You commit only when the voice lands.
* Quality that fits the use case  
Default for speed, Ultra for flagship content, Minimax for longer source recordings. Match the model to the job.
* A voice exclusive to your product  
A designed or cloned voice serves only your product. Your IVR, your agents, your TTS, all sounding like you.
* Voice infrastructure included  
Create, store, and deploy from the same platform that carries your calls and runs your agents. Your voice lives where your speech happens.
* Built for live voice  
Voice Design outputs work in real-time AI Assistants, Call Control, and the TTS WebSocket. The voice is ready for live conversation, batch synthesis, and everything between.

HOW IT WORKS

## From idea to production voice
