Over the past few years, voice assistants have become quite common in households. Of course, all modern phones come with one built-in, and even smart speakers have gained popularity. A Nest speaker, an Amazon Echo, or an Apple Homepod can be found in quite a lot of households these days. While it's extremely convenient to use your voice to perform tasks, one of the biggest concerns with an always-on microphone is privacy. These assistants listen to you and store your queries to improve accuracy, and while that may sound beneficial, you may not want certain sensitive data to be saved. This is why deleting your assistant's voice history from time to time is a good idea. Here's how you can delete your voice history from Alexa, Google Assistant, and Siri using a few simple steps.

Note that the steps vary depending on the voice assistant you use. Some devices will let you erase your voice history via the speaker itself, while some may require you to do it via the app on your smartphone. We will mention all possible ways that you can delete voice history so that you can follow the one that's convenient for you.
