Abstract
A home assistant device and a method for privacy-preserving vocal interactions. A microphone captures an audio signal corresponding to a vocal user query. The identity of the speaker is determined, and an obfuscated name is generated corresponding to the identified speaker. The audio signal is analysed to determine the intent of the user and a personalized answer is generated in combination with the obfuscated name. This answer is then de-obfuscated by reintroducing the speaker name. The de-obfuscated answer is rendered to the speaker.
