# Play sounds when a letter is shown

To implement typewriter sounds in your game, you can subscribe to the Typewriter’s `FOnCharacter` delegate and play sounds based on it.

The delegate passes a `FString` as a parameter, so you can play different sounds based on different letters as well.

{% hint style="info" %}
The delegate is also triggered with spaces, so be sure to play sounds based on the type of character you prefer.

### Extras <a href="#example-package" id="example-package"></a>

Inside the `Plugins/TextAnimatorFebucci Content` folder (either among your engine content or not depending on how you set up the plugin) you will see an "Extras" folder.

Inside you will find the **Extra\_TypewriterSound** level, some audio clips and a Widget Blueprint. By opening and playing the level, you'll see some text which produces typewriting SFX. Finally, by opening the blueprint you can see how the example was implemented.

You can also find two customized effects in C++ and Blueprint. Feel free to add them in your projects or as a starting point to create your owns!
