Browser Extension

Browser Extension

Overview

Chrome/Firefox extension that listens continuously.

Advantages

Always running when browser is open
Can access microphone across all tabs
Persistent background script
No need to keep a specific tab open

Implementation

manifest.json

{
  "name": "Hey LARS",
  "permissions": ["microphone", "background"],
  "background": {
    "service_worker": "background.js"
  }
}

Background Script

// Continuous listening in background
chrome.runtime.onStartup.addListener(() => {
  startWakeWordDetection();
});

function startWakeWordDetection() {
  // Get microphone access
  // Stream to wake word detector
  // On detection, open Nexus panel
}

Considerations

Chrome Manifest V3 has some limitations
Need to handle microphone permissions carefully
Good for desktop use cases
