Spelling Hero is a spelling bee simulator designed to replicate the experience of participating in a spelling competition. Users can select their desired difficulty level, and the browser will pronounce a word aloud for them to spell correctly. The game's data was manually curated, with each word including its definition, origin, type, and a sample sentence. Spelling Hero utilizes Deepgram Speech Recognition API for voice input understanding and P5.js for its user interface. The code is available on GitHub, and feedback is welcome through the project's GitHub discussions.
