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

Cobra requires a valid Picovoice AccessKey at initialization. AccessKey acts as your credentials when using Cobra 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.

1. Use yarn or npm to install the dependencies
2. Run 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 Cobra and the WebVoiceProcessor have initialized. Start speaking and Cobra will display voice probability on the screen.
