I built an AI commentator that screams about your sourdough like it's the World Cup final

Short summary

GOLAZO is a single-file web app that turns any described moment into over-the-top sports commentary using Gemini 2.0 Flash for text generation and ElevenLabs for expressive multilingual voice synthesis. Users pick a commentator persona, language, and intensity level, then receive streamed text and audio commentary that treats mundane events like World Cup goals. The project includes thoughtful prompt engineering to enforce sincerity over irony, accessibility fallbacks via Web Speech API, and reduced-motion support.
