Building a Karaoke Machine with Angular and HTML5 Speech Recognition
summary
A web-based karaoke machine built with Angular uses native Audio plus LRC files for lyric timing and rxjs fromEvent to keep audio and captions in sync, and it uses HTML5 Web Speech Recognition + rxjs to capture transcripts. Scoring compares transcript words to recent lyric lines (a surprise: 5 points per word), the demo is a proof-of-concept with only 2 songs and a live demo glitch suggests microphone or browser limits affect reliability.
