Information technology giants such as Google LLC and Amazon.com Inc. are striving to reassure consumers of their commitment to privacy and security, emphasizing related features while rolling out new products at the CES electronics trade show in Las Vegas.

Google announced Tuesday that it had added two new voice actions to help consumers better control the privacy settings on its voice assistants. If users say, "Hey Google, that wasn't for you," Google Assistant will forget the unintended activation. Users can also alter their privacy preferences by simply asking, "Hey Google, are you saving my audio data?"

Ring Inc., an Amazon unit specializing in home security devices, revealed Monday an update to its mobile app called Control Center that allows users to view and change their privacy and security settings. The privacy dashboard will be available later this month.
