Make a call
Here are some of the things you can say to make calls:
Say "Ok Google,” then:
- "Call [business name]."
- “Where is the nearest [business]?” then “OK Google,” “Call them.”
- “Call [phone number].”
- "Redial."
- "Call [contact name]."
- "Video call [contact]"
- “Call [display or speaker name]”
The availability of commands will vary depending on the calling methods set up on your device. For example, if you’ve set up Duo calling and turned on personal results, you’ll be able to say “Video call [contact]” to make video calls. On displays, touch controls are also available when you set up household contacts. Learn more about setting up and making calls with Duo calling, Google supported calling, and mobile calling.
Use the Google Assistant while on a call
When you’re on a call, you can use voice commands related to your call. For example, ask to lower the volume of your call. Some queries not related to your call are not available while the call is active.
When you’re on a call, the person you are calling will hear you say “Ok, Google,” then the call will be muted while you complete your request. If you are making a video call, the call will be muted but the camera feed will continue streaming.
Frequently asked questions
What does my Google speaker or display record?
Google will record voice commands after “Ok Google” or “Hey Google.” For example, “Hey Google, call Bob” or “Ok Google, hang up.” would be recorded. The recording stops after that phrase.
Google doesn't record the phone conversation.
If I have multiple numbers associated with a contact, which one will my device call?
With Google supported calling and mobile calling, the Google Assistant will ask you which number you would like to call. Eventually your Assistant will learn which number you prefer for certain contacts so that you can skip this step in the future. You can also edit your contacts to make them more unique at contacts.google.com.
With Duo calls, your device will call the number with a valid Duo account.
Can someone call me on my Home or Nest device (versus me calling them)?
You can receive calls made by someone using Google Duo.
To receive calls:
- Duo calling needs to be set up for your the device.
- Personal results need to be on.
- Do not disturb needs to be off.
- Night mode needs to be off.
- Downtime needs to be off.
Google supported calling and mobile calling (except with Telstra) do not support incoming calls.
Can I block people from calling me on my speaker or display?
You can only receive calls made by someone using Google Duo. Learn more about blocking numbers on Duo.
You can also temporarily block all calls by turning on Do not disturb. Note: This will also disable incoming broadcasts and reminder notifications. To prevent call notifications on a regular schedule, set up night mode.
What happens when you reach a number that has a menu and says “press 2”?
Use your voice to navigate through a phone tree. When the phone system gives you the prompt for the option you want, such as “press 2,” say “OK, Google, press 2.” With a Nest Hub or Nest Hub Max display, you can also use the dial pad 
Note: With Duo calls, you will not be able to use Voice commands in a call to navigate a phone system.
