The first thing you need to do is install the Google Assistant, which is available to download from the Google Play store and can be purchased with a Google Cardboard VR headset.
Once installed, you can access the Google Voice search function and access a full range of voice commands to listen to audio files or text.
To turn on the Google Cast app, you need the Google Home app, and the Google Camera app is included.
Google has also provided a number of apps for the Google Cardboards.
Google Cast has a few features that are worth noting, though the one I find most useful is the ability to send audio and video messages to your Google Assistant.
When paired with the Google Pixel phone, the Google Chromecast will also work.
The Google Cast is designed to work with all major mobile and home electronics, but it is currently limited to the Google home.
You can check out the GoogleCast page to learn more.
The app is also compatible with both iOS and Android, so you can also use it with Google Home or Google Cast on Windows PCs and Macs.
