Voice AI Browser Extension for Google Chrome

This is the source code for building the Voice AI Browser Extension for Google Chrome. The extension allows you to use Picovoice Porcupine to listen for a wake word, and then uses the SpeechRecogniton API to perform a Google Search via voice.

The extension serves as small but useful tool for performing voice searches with a wake word. The extension source code provides a fully functional proof-of-concept implementation of Picovoice's WASM-powered offline Voice AI used with the WebExtension API.

The extension use webextension-polyfill via so that all of the WebExtension APIs are promise-based in Chrome, instead of callback-based.
