The Google Assistant is a voice assistant developed by the technology company Google. Comparable competitors with similar functionality include Amazon Alexa and Apple's Siri.
The Google Assistant is pre-installed on Android smartphones and tablets, and on the Google Home smart speaker. The Google Assistant is activated by saying "Ok, Google!" This is followed by the actual question or instruction. For example: "Ok, Google! What does WiFi mean in German?" The Google Assistant then answers the question via voice output within seconds.
In the smart home context, the Google Assistant offers support for controlling smart home components. For example, you can turn the lights on and off, lower the blinds, increase the heating, or disable the alarm system using voice commands.
