Getting to Know Google Assistant and What it Does

Google Assistant is an AI-powered virtual assistant developed by Google primarily for mobile and smart home devices. It may also be used on smart displays, smartwatches and in your car.

A step up from its predecessor, Google Now, it can now engage in two-way conversations because of its AI and machine learning technology.


Interaction with the Google Assistant is primarily done though the natural voice but it also supports keyboard input. Among its capabilities are searching the internet, scheduling events, and adjusting device settings.

Brief History of Google Assistant

Google Assistant was introduced during Google’s developer conference in May 2016 as part of the unveiling of the Allo messaging app and the Google Home smart speaker.

Google Assistant was initially exclusive to the Pixel and Pixel XL smartphones but was eventually rolled out for other Android smartphones in February 2017.


At launch, the voice of Kiki Baessell was used but the Assistant’s default voice from 2016 to the present is that of Antonia Flynn. An option to change the voice to that of Issa Rae was introduced in October 2019.

Examining the Capabilities of Google Assistant

Google Assistant has a wide range of capabilities that fall under voice searching, voice commands, and voice-activated device control.

Because the Google Assistant has no specific name unlike Alexa or Siri, you initiate a task by saying “Ok Google” or “Hey Google”. You don’t need to say these phrases repeatedly once you’ve started a conversation.

Using Google Assistant, you will be able to control your devices and smart home, access your personal information such as calendars, and search for information online like restaurant locations and weather forecasts.

Even More with Google Assistant

In terms of entertainment, you can ask the Google Assistant to control your music, play media from Chromecast and other compatible devices, and even play games.

For productivity, you can use the Google Assistant to run timers and set reminders and alarms, make appointments, and draft and send messages.

You can also command it to open apps on your smartphone, read notifications aloud to you, and even ask it to do real-time spoken translations when listening to foreign language audio.

Find Out How Google Assistant Understands You

To be able to fulfill your request, Google Assistant needs to first understand what you asked it. Once you issue a request, Google’s speech recognition technology converts the audio to text.

The converted text will then be analyzed by Google Assistant. It does this by combining it with other useful information, such as recent requests or the type of device you’re using, to come up with possible interpretations.

It then creates a list of these interpretations and possible responses. Google Assistant weighs these options and ranks them to determine the best way to fulfill your request.

How it Evaluates Possible Responses to Requests

There are several factors that help Google Assistant rank the available responses to your request. It assesses how certain it is that it understood your request and whether a response is actually available.

It also considers how satisfied previous users with similar requests were with a particular response and how recent that response was created. It also looks at the compatibility of the response to your device.

Google Assistant also makes use of the data from your other recent requests, what you are currently doing on your device, and could also manually curate some high-quality responses to rank higher.

Setting Up Google Assistant on Android Devices

If you’re an Android device user, setting up Google Assistant is pretty simple. Since Google Assistant comes pre-installed on the most recent Android devices, you no longer need to download it or enable it.

Downloading and Installing the Google Assistant App for Older Android Devices

The Google Assistant app may not be pre-installed for older phone models. In this case, you may search for the app on the Google Play Store and find it in the Productivity category under the name, Google Assistant.

The app, currently rated at 4.2 out of 5 stars based on over 483,000 user reviews, has a file size of 1.3 MB and will require your device to run on Android 5.0 and up in order to function properly.

Thankfully, there's a way for Assistant to give you answers without having anyone nearby hear them. 

You can turn off Google Assistant's speech output so that it will just show you responses on your device's screen without saying them out loud.
