# OpenAI GPT Live Voices

> Configure OpenAI GPT Live speech-to-speech voices for faster, more natural voice assistant conversations.

OpenAI GPT Live is a speech-to-speech model that listens and speaks in one step, enabling faster and more natural voice assistant conversations. Unlike traditional text-to-speech systems, GPT Live processes audio input directly and generates spoken responses without an intermediate text transcription step.

## Available Voices

GPT Live offers 22 voices:

* Alloy
* Ash
* Ballad
* Breeze
* Cedar
* Coral
* Cove
* Echo
* Ember
* Fable
* Glimmer
* Juniper
* Marin
* Meadow
* Nova
* Reef
* Ridge
* Sage
* Shimmer
* Vale
* Verse
* Whisper

You can preview any voice in the Voice library before switching.

## How to Configure GPT Live

**1. Open Voice Settings**

Open your assistant and navigate to Voice settings, then Voice library.

**2. Select Provider and Voice**

Set Provider to OpenAI GPT Live and choose a voice from the catalog.

**3. Choose Chat & Tools Model**

In the assistant header, select a separate AI model to handle tool actions (bookings, lookups, transfers) and chat replies. This ensures your assistant retains all its capabilities while using the GPT Live voice.

**4. Publish**

Click Publish to make your changes live.

## Important Considerations

* Switching to or from a GPT Live voice requires a full Publish operation.
* GPT Live voices cannot be used together with a connected Flow.
* Transcription and voice-tuning settings do not apply when using GPT Live, since the model handles both hearing and speaking directly.

## Chat & Tools Model

Because GPT Live is a speech-to-speech model optimized for conversation, you must select a separate Chat & tools model to handle:

* Tool function calls (appointment bookings, contact lookups, call transfers)
* Chat message replies
* Structured data extraction

This separation ensures your assistant maintains full functionality while benefiting from GPT Live's natural conversational flow.
