Obiente Translate is a lightweight app for live, multi-source transcription and instant translation. It turns spoken conversations into readable text in real time and presents them in a clean, distraction-free "Focus" view — ideal for events, kiosks, and live captioning.

Why people use it

• Make spoken content readable and shareable instantly.
• Help multilingual audiences follow live conversations in real time.
• Perfect for online calls, language exchange, and multilingual friendships.
• Provide a clear, centered display for public installations and events.

Core features

• Live transcription from microphones and system audio.
• Optional real-time translation into target languages.
• Focus Mode: line-by-line, centered Lyrics style display.
• Participant chips for quick toggling and speaker clarity.
• Voice Activity Detection (VAD): Automatically filters out silence and background noise, reducing network traffic and preventing hallucinations from silent audio chunks.
• Noise Gate: Suppresses low-level audio to improve transcription quality.

Quick start

pnpm install
pnpm dev    # start the dev server (usually http://localhost:3000)

Build for production

pnpm build
pnpm preview

To optimize network usage and transcription quality, the app includes intelligent audio filtering:

• Automatically detects whether audio contains speech or just silence/noise
• Prevents sending empty chunks that waste bandwidth and cause hallucinations
• Uses RMS energy analysis and Zero Crossing Rate (ZCR) detection
• Only sends audio chunks when actual speech is detected

• Suppresses low-level background noise and hiss
• Applies envelope-following gain reduction with configurable attack/release
• Cleans up audio before sending to the transcription server
• Default threshold: -40dB (ratio: 10:1)

The filters automatically scale to the audio sample rate. Default settings:

• Energy threshold: 0.01 (RMS)
• Max ZCR: 0.3 (higher = more noise-like)
• Min speech duration: ~0.1 seconds
• Noise gate threshold: 0.01 with 10:1 ratio

TL;DR Obiente Translate makes international speech readable and accessible in real time with a minimal, usable UI.
