Add Sound Feedback for Answer Submissions

I really enjoyed the project and website; it reminded me of playing Duolingo. To enhance the user experience, I suggest adding audio feedback when an answer is submitted. This could include:

A sound for correct answers.

A different sound for incorrect answers.

Benefits:

Provides immediate feedback to users.

Makes the interaction more engaging and fun.

Enhances the overall user experience by adding an element of gamification.

Implementation:

Add sound files for correct and incorrect answers.

Trigger the appropriate sound when an answer is submitted based on its correctness.

Start by locating the frontend entry point that handles answer submissions and checking how static assets are currently loaded. Add distinct audio feedback for correct and incorrect answers, then verify that the appropriate sound plays after each submission.
