# Multiple Voices in BotTalk Articles

***

### Step 1: Activate SSML Tag Support in Audio Rules

To begin using different voices, you must first enable SSML tags in your BotTalk project settings.

1. Go to your **Test Project**.
2. Navigate to **Audio Rules**.
3. Enable the option that allows SSML when the article label is set to `"interview"`.

📸 *Refer to the image below for the correct setting toggle.*

### Step 2: Label the Article

To activate SSML usage in a specific article:

1. Open the article in the BotTalk editor.
2. Add the label **`interview`**.

This tells the system to interpret SSML tags, including `<voice>`, in the article content.

📸 *See the image below on where to add the label.*

Of course you can use [our API](/docs/help/endpoints.md#articles) to give labels programmatically.&#x20;
{% endhint %}

### Step 3: Insert SSML Voice Tags

With the article labeled and SSML enabled, you can now add voice-specific tags within your article content:

```xml
<voice name="de-DE-MatildaXI" vol="-10">
  This is the voice number one
</voice>

<voice name="de-DE-RobXI" vol="40">
  And this is the voice number two
</voice>

```

Each `<voice>` tag allows you to:

* **Specify a voice** using the `name` attribute.
* **Adjust volume** using the optional `vol` attribute, which accepts numerical values (positive = louder, negative = softer).

💡 *Different voices may have different natural volumes, so the `vol` attribute helps balance audio levels for a smoother listening experience. You can also set* [*an audio rule determining volume boost for a specific voice*](/docs/text-to-speech/automation-rules.md#volume-boost)*.*

***

### Tips

* Always test your output to ensure voice transitions sound natural.
* Use volume adjustments conservatively to avoid clipping or overly quiet segments.
* Combine with pauses or prosody tags for advanced speech tuning.
