Here’s how to switch your Google Assistant’s voice to a male:
It should be noted that Google itself doesn’t say the voices have genders assigned to them. They’re labeled as “Voice I†and “Voice II.†But the second voice was likely added because consumers have questioned why all digital assistants have female voices activated by default.
Siri, Alexa, and Cortana have all been based on females. The more general name has allowed Google Assistant to stay away from similar scrutiny, but the sole voice it shipped with was just another female. Adding a second, male voice makes Google Assistant a bit more friendlier and proves any gender makes a good digital assistant.
