Smart speakers provide a convenient, often hands-free way for a user to interface with smart technology. For instance, if a user receives an email, text message, or other communication, the communication can be played aloud via the smart speaker. However, it may not be desirable for a communication containing personal or otherwise sensitive information to be read aloud. As such, systems and methods are needed that can provide enhanced privacy of smart speakers while maintaining expected functionality of smart speakers. Furthermore, authenticating a user based on audio alone can be challenging and may be less secure than other forms of authentication.
