koala-web-demo

This is a basic demo to show how to use Koala for web browsers, using the IIFE version of the library (i.e. an HTML script tag). It instantiates a Koala worker engine and uses it with the @picovoice/web-voice-processor to access (and automatically downsample) microphone audio.

AccessKey

Koala requires a valid Picovoice AccessKey at initialization. AccessKey acts as your credentials when using Picovoice SDKs. You can get your AccessKey for free. Make sure to keep your AccessKey secret. Signup or Login to Picovoice Console to get your AccessKey.

Install & run

Use yarn or npm to install the dependencies, and the start script to start a local web server hosting the demo.

yarn
yarn start

(or)

npm install
npm run start

Open localhost:5000 in your web browser, as hinted at in the output:

Available on:
  http://localhost:5000
Hit CTRL-C to stop the server

Wait until Koala and the WebVoiceProcessor have initialized. Record audio or upload an audio file to enhance audio.
