Some queries to a virtual assistant may seek information specific to that particular user. In some of these instances, the query and/or the response may contain information that the user considers to be private. In such cases, if a virtual assistant delivers the response in the form of audio, such delivery can potentially reveal the user’s private information to others who might be in the vicinity, close enough to hear the spoken response from the virtual assistant. This disclosure describes techniques that automatically adjust response delivery by a virtual assistant whenever a user’s voice query and/or the information in response to the query are determined as likely to include private information. Delivery of the response is adapted to present the private information in a manner that avoids it being overheard.
