# Play sounds when a letter is shown

To implement typewriter sounds in your game, you can subscribe to the Typewriter’s “`OnCharacterVisible`” event and play sounds based on it.

The event passes a “char” as a parameter, so you can play different sounds based on different letters as well.

*P.S. The event is also triggered with spaces, so be sure to play sounds based on the type of character you prefer.*

As an example, you can install the “TypeWriter Sounds” package found inside the “Extra” folder and check its implementation.
