Voice assistants are great, but you need to know how to control your data.

It probably goes without saying that voice command technology has changed the way we work and relax.

If anyone in an office needs a reminder on what is on their schedule today, all they need to do is ask Alexa or their Google Assistant to get a refresher. If a student is up at night scrambling to finish a research paper, they can ask Siri and Cortana for some information on a topic.

As great as these devices are, sometimes they have an overabundance of voice commands on them. There’s also the added (justifiable) paranoia of employees of the manufacturers listening to the commands as well.

That being said, with that in mind, there are ways to delete the voice commands. And the methods on how to do that are easy. Most of them require a working computer in order to log into accounts tied with the devices.

Want to know how to delete your commands on all of those devices listed above? Read on.

Amazon Alexa
