Google has now admitted the recordings were leaked. "We just learned that one of these language reviewers has violated our data security policies by leaking confidential Dutch audio data," Google product manager of search David Monsees said in a blog post. "Our Security and Privacy Response teams have been activated on this issue, are investigating, and we will take action. We are conducting a full review of our safeguards in this space to prevent misconduct like this from happening again"
Monsees said its partners only listen to "around 0.2 percent of all audio snippets" and said they are "not associated with user accounts," even though VRT was able to figure out who was speaking in some of the clips.
If this worries you, you can delete your old Google Assistant voice history pretty easily .
Amazon also collects voice clips when people speak to Alexa and also uses humans to analyze clips . You can stop Alexa from using the clips to improve Amazon's service, however, and delete your past recordings .
