{% endhint %}

### Enabling the TTS Extension

To enable the TTS Extension, follow these steps:

* Go to **Settings -> Extensions -> Text to Speech**
* Toggle the switch to **On**
* Relaunch the app

***

### Creating a New TTS List

* Click the **New List** button to create a new TTS list

***

### Adding Voices to a TTS List

* Click on the **TTS name** to open the **Voice Editor**
* Click the **Add Voice** button to add a new voice entry
* In the **Character Name** field, enter the character name associated with the voice
* In the **Text Source** field, select the input source for the TTS voice. You can choose between:
  * **Source Text** - Uses the original text as the TTS input
  * **Target Text (Translation)** - Uses the translated text as the TTS input

#### About Character Names

The character name is used to determine which voice will be played based on the text source. Below are the available options:

* **Default** or **None** - Defines the default voice that will be played when no matching character name is found in the source text or translation
* **"%" Pattern (Wildcard)**  - Use the `%` wildcard to define a dynamic name pattern. For example, if the source text contains `Anita: Hello World`, you can enter `Anita%` as the character name to match it
* **Multiple Character Names** - You can enter more than one character name by separating them with a comma (`,`). For example: `Ani%, Amelia%`
