Shape a custom voice for your app with a prompt (GPT-Live-1)
OpenAI Developers published a guide on giving GPT-Live-1 apps a voice that fits: you can shape a voice with a prompt or choose from new international preset voices. Useful if your voice agent sounds generic or wrong for your audience.
Why it matters
A voice that matches your brand and market makes a voice agent feel trustworthy instead of robotic.
Who it's for
Developers building voice agents with GPT-Live.
How to try it
- Read the guide linked from the OpenAI Developers post.
- Describe the voice in your instructions (tone, pace, accent) or pick an international preset.
- Test with real users in each market and adjust.
Plan & availability: OpenAI API (GPT-Live-1). See the OpenAI Developers guide for voice options.
