VocaLearn – Real-Time AI Language Tutor 🎙🌍
This is a submission for the Murf AI Coding Challenge 2
🧠 What I Built
VocaLearn is an AI-powered language learning platform that simulates natural conversations using real-time speech recognition, intelligent AI replies, and Murf’s lifelike voice responses. It helps users speak confidently, get real-time pronunciation feedback, and practice real-world scenarios — all without needing a human tutor.
You choose a scenario → Speak into your mic → The AI responds naturally → Murf voices deliver it back with native pronunciation.
Simple. Powerful. Immersive.
