(CNN/Money) A major flaw has been detected in the newly-unveiled Google Home Mini speaker that allows it to secretly record conversations without users knowing.

Last week, Google showed off its next-generation smart speakers at an event in San Francisco. Following the event, it sent members of the press home with a review unit of the Google Home Mini, expected to launch on October 19.

Android Police tech blogger and founder Artem Russakovskii was the first to discover a bug in the software used by those devices. After using the gadget, he went to his Google (GOOG) activity account page and noticed it was populated with audio clips recorded in his home.
