Install the NPM packages

Using Picovoice with Angular requires installing three packages: the binding package, @picovoice/picovoice-web-angular, the language-specific web worker package (e.g. @picovoice/picovoice-web-en-worker), and @picovoice/web-voice-processor.

Use yarn or npm to install the packages to your project:

yarn add @picovoice/picovoice-web-angular @picovoice/picovoice-web-en-worker @picovoice/web-voice-processor

(or)

npm install @picovoice/picovoice-web-angular @picovoice/picovoice-web-en-worker @picovoice/web-voice-processor

Demo application

There is a Angular demo project available on the Picovoice GitHub repository. The demo project was bootstrapped with Angular CLI.

Clone Picovoice GitHub repository

If using SSH, clone the Picovoice repository with:

git clone --recurse-submodules [email protected]:Picovoice/picovoice.git

If using HTTPS, then type:

git clone --recurse-submodules https://github.com/Picovoice/picovoice.git

Install dependencies and run

Use yarn or npm to install the demo dependencies and start it:

yarn
yarn serve

(or)

npm install
npm run serve

Open http://localhost:4200 to view it in the browser.

Try Picovoice SDK

Say the wake word "Picovoice", followed by a phrase in the "Alarm Clock" context, e.g.:

"Picovoice, Set a timer for ten seconds"

Rhino's inference result will appear:

{
  "isFinalized": true,
  "isUnderstood": true,
  "intent": "setTimer",
  "slots": { "minutes": "1" }
}

The engine will reset to Porcupine, and it will once again be listening for the wake phrase "Picovoice". Try another interaction, and this time use a phrase outside of the Rhino context:

"Picovoice, tell me a joke"

{ "isFinalized": true, "isUnderstood": false, "intent": null, "slots": {} }
