If you don't like Google Apps Assistant's default voice, don't worry because it's pretty easy to change. There are 10 assistant voices available – five male and five female – and here is everything you need to do to give it a new sound or even accent.
Method 1: Use the Google Home Page
First, find the Google Home app on your device and open it.
Next, look in the lower right corner of the circular icon with a face inside it and click on it.
This provides your account settings. Click Settings and then on the next page click Assistant at the top of the line.
You should now see an option for Assistant Voice.
Click on it and you will land on a voting tool where you can choose from any of the voices offered. Listen to them all and choose the one you like.
Method 2: Just "OK Google"
There is another way to get to the same screen .
Cancel Google Assistant by saying "OK Google" and look for the compass icon at the bottom right of the screen.
Click on it and you will land on a Google Assistant settings page. Click on the three vertical dots at the top right and select settings.
Then you review the settings page details above. From there, the steps are the same: Select Assistant from the four options at the top, click Assistant Voice and then select a voice.
The ability to change voices is available universally. Google rolls it out slowly, so if you don't see it yet, you can assume it probably hasn't reached your language or language in your account.
Note: The setting does not only change as your phone talks to you. It also goes on to other Google Assistant devices in your account, such as Google Speakers.
