I’m looking for a custom-built web app that turns any spoken Hinglish—whether it comes from my microphone or the audio playing on my computer—into on-screen text instantly. The transcription must keep Hindi words in Devanagari while leaving English words in the Roman script, exactly like this sample snippet: noida के कुछ ऐसे sectors में बाढ़ आई है कि जिनके करोड़ों के घर हैं, वो उन करोड़ों के घर के सामने इतना-इतना पानी भरा हुआ है… Scope • Real-time transcription is the only feature I need right now; no additional languages, history logs, or text editors. • The page should start listening as soon as I hit “Start” and stream the output line by line with minimal latency. • Audio can come from system sound or mic, so please integrate a solution comparable to screen-share audio capture (Web Audio API, WebRTC, or a lightweight helper where browsers restrict direct system capture). • Accuracy in code-mixed contexts is key; you’re free to combine APIs or models (e.g., Google Speech-to-Text, Azure, Whisper) as long as the final text respects the Hindi/English split. • The UI can stay simple—just a clean panel that shows the live feed and a “Copy All” button. Deliverables 1. Front-end (HTML/CSS/JS) with the live transcript window. 2. Back-end service or worker that streams recognition results. 3. Deployment guide so I can run it on my own server (Linux preferred). 4. Brief README outlining any API keys, rate limits, or model setup. I’ll test by playing a five-minute Hinglish news clip; acceptance hinges on seeing the mixed-script output appear in real time with a lag under two seconds.
