# Voice Selection & Voice Cloning

> Learn how to select built-in voices or clone your own voice for your AI assistants

Your AI assistant can speak with **built-in voices** or a **custom cloned voice**. Natural, realistic voices increase customer trust and engagement.

## TTS Provider

Select your Text-to-Speech provider in the assistant settings. Available in **Pipeline** and **Dualplex** modes.

**Available Providers:**

* **ElevenLabs** - High-quality voices
* **Cartesia** - Fast, low-latency synthesis

The TTS Provider dropdown appears after selecting a language.

## Voice Library

Each TTS provider has its own voice library. Select male/female, accent, or language based on your provider.

## Importing Voices from the Provider Library

Beyond the built-in catalog, you can import any public voice from your TTS provider's own library (ElevenLabs Voice Library or Cartesia Library). Available in **Pipeline** and **Dualplex** modes.

**Steps:**

1. Click "Import voice" next to the voice selector
2. Pick the provider (ElevenLabs or Cartesia)
3. Open the provider's voice library and find a voice you like
4. Copy the voice link or ID (the ⋮ menu next to the voice)
5. Paste it in the import field and click Import

You'll get a notification when the voice is ready — it then appears in the voice picker like any other voice, billed at the same flat per-minute rate.

**Notes:**

* ElevenLabs voices with a custom price set by their creator cannot be imported.
* Private or unshared voices cannot be imported — only public library voices.

## Voice Cloning

Clone a voice from an audio sample. Available in **Pipeline** and **Dualplex** modes.

**Clone to Provider:**

* **Cartesia** - Single audio file, at least 10 seconds, 1 speaker, no background noise
* **ElevenLabs** - Samples over 1 minute, 1 speaker, no background noise. Max 5 minutes total. Quality over quantity.

**Steps:**

1. Click "Clone voice" next to voice selector
2. Select provider (Cartesia or ElevenLabs)
3. Choose the voice language
4. Enter a name for your voice
5. Record or upload audio
6. Wait for processing
7. Select your new voice from dropdown

## Best Practices

1. **High-Quality Audio**: Clearer samples give better results
2. **Steady Delivery**: Natural tone, no abrupt changes
3. **No Background Noise**: Record in a quiet environment
4. **Legal**: Ensure permission to clone voices that aren't yours

**Tip:** After selecting or cloning a voice, do a test call to confirm it sounds as expected.
