Following the previous release of the Customize Voices with Your Chatbot, we are excited to extend custom voice support to real-time voice-to-voice chat. With this feature, you can replace the native voices of OpenAI with your own customized voice from ElevenLabs while still enjoying all the powerful features of OpenAI's real-time voice functionality.

How to use it

  • You can simply turn on the 'User Customize Voice' toggle in the Realtime Voices settings. Then, the output voices of the real-time communication will switch to your chosen voices configured in the Customize Voices settings, as shown below.
Enable User Customize Voice in the Realtime Voices settings

After enabling the feature, the output voices of the real-time communication will switch to your chosen voice while maintaining all the other features of the real-time voice-to-voice chat. Because you are using your own customized voice, users cannot select OpenAI's provided voices in the Chatbot interface anymore.

You can watch this Demo Youtube video to see the experience:
