What the sounds tell you
Sound is a fast feedback channel: a click confirms a correct key and a different cue flags a mistake, so you notice errors without watching the screen closely. Many learners find this speeds up muscle memory.
Turning sound on or off
Use the sound toggle to mute or unmute typing audio whenever you like. Your choice is remembered, so you do not have to set it every session. This is handy in quiet shared spaces.
No sound at all?
If you expect sound and hear nothing, see how to fix audio not working. You can also adjust other preferences from your profile and settings.
