# Rime

> Learn how to use Rime's Coda and Mist v2 TTS models with SignalWire AI Voice applications.

Rime offers uniquely realistic voices with a focus on natural expressiveness.

## Models

| Model               | Description                                                                       |
| ------------------- | --------------------------------------------------------------------------------- |
| `coda`              | Rime's flagship model, with top-rated, ultra-realistic voices                     |
| `mistv2`            | **Default** - Updated version of mist                                             |
| `arcana` Deprecated | Retired by Rime. Requests for `arcana` are served by `coda` — use `coda` instead. |
| `mist` Deprecated   | Fast, precise model for business applications                                     |

#### [Coda](https://docs.rime.ai/api-reference/models#coda)

Coda is Rime's flagship model, pairing a sophisticated LLM backbone with a dedicated
speech inference engine for top-rated, ultra-realistic voices.

#### [Mist v2](https://docs.rime.ai/api-reference/models#mist)

Mist is Rime's fastest model, built for high-volume, business-critical applications.

## Voices

Mist v2 is the default Rime model on the SignalWire platform.
To use this model, simply set the voice ID.

To use Coda voices, set `model` to `coda` with the
[**`languages`**](/docs/swml/reference/ai/languages#use-voice-strings)
SWML method:

```yaml
languages:
- name: English
  code: en-US
  voice: rime.luna
  model: coda
```

## Build with Rime on SignalWire

### Create a Space and add credit

If you don't have one yet, you'll need to
[create a SignalWire Space](/docs/platform/signing-up-for-a-space).
Be sure to add some credit to test with.

### Add a new Resource

Navigate to the **Resources** tab in your [SignalWire Dashboard](https://my.signalwire.com) and click **+ Add New** to create a new Resource.

### Create a SWML Script

From the Resources menu, select **SWML Script**.
Name it something fun and recognizable.
Ours is titled Rime Wizard.

Next, paste the following starter script into the text box, and hit <kbd>Save</kbd>:

```yaml
version: 1.0.0
sections:
  main:
  - ai:
      prompt:
        text: | 
          You're Luna, a voice from Rime's Coda model! 
          Introduce yourself, and have a conversation about programmable unified communications on the SignalWire platform. 
      languages:
      - name: English
        code: en-US
        voice: rime.luna
        model: coda
```

### Buy and assign a phone number

Navigate to the **Phone Numbers** section of the Dashboard's left sidebar menu.

Purchase a phone number and assign it to the desired SWML script.

In the Dashboard, open **Phone Numbers** > **Purchased**, select the number, and open its edit page. Under **Inbound Call Settings**, select **+ Assign Resource**, choose the SWML script, and save the settings.

### Give it a call!

Call the number you just assigned to chat with your new AI voice application on the phone.

## Next steps with SWML
