Personalized virtual personal assistant for multiple users in audio zones
A recently granted patent (Publication Number: US11928390B2) discloses a method for a computing system to provide virtual personal assistants (VPA) among a plurality of audio zones. The method involves assigning multiple VPA instances to different users, each operating concurrently, monitoring audio zones for user requests, determining the origin of the request based on audio signal strength, and broadcasting a VPA response through speakers in the corresponding audio zone. The system retrieves personalized VPA configurations for users based on audio samples, identifies users through audio samples using Mel Frequency Cepstral Coefficient (MFCC) features and a deep neural network, and adjusts speaker settings based on vehicle system inputs like speed, ambient noise, and location.
The computing system described in the patent includes multiple speakers and microphones, a VPA system with concurrent VPA instances, and a user recognition system (URS) for identifying users based on audio samples. The system further comprises a speech-to-text engine, language processor, and text-to-speech engine for VPA operations. Instructions stored in a non-transitory memory allow the system to assign VPA instances to users, retrieve configurations from a remote server, and respond to user commands. Additionally, the system can be integrated into a motor vehicle and communicate with external devices like cloud-based services, mobile phones, tablets, laptops, desktops, smartwatches, smart glasses, and servers hosting proprietary applications, enhancing user experience and accessibility across various platforms.
