Smart speakers like Amazon Echo, Apple HomePod, and Google Home are becoming increasingly popular, especially for listening to music. From answering questions to controlling the smart home, however, much more is needed.
These speakers have microphones that wait for a "wake-up word" or a phrase that puts the speaker in full listening mode. On Google Home devices that use the Google Assistant, the activation word is either "Hey Google" or "Okay Google," whichever you prefer. (If you want, you can turn off all active listening, even though it overrides the purpose of a smart speaker.)
To learn more about you and provide the best answers (and ads), Google stores the audio of your questions and instructions to the Google Assistant. Do not be shocked – companies like Google and others are not in the habit of deleting your personal information when not required.
Echo devices had problems with that. As of this summer, this will also apply to Google (and Microsoft and Apple).
Fortunately, you can clear your history with Alexa on the Amazon Echo, as well as the history of any messages you send to Google Assistant, whether through Google Home or even through your smartphone.
