System and method for a voice-activated user support system
The concepts include a user support system in the form of a microphone, a visual display arranged in a vehicle cabin, and a controller. The controller includes an instruction set that is executable to receive, via the microphone, a voice-based request from a user, and employ a virtual assistant to determine a user interaction in real time and to determine a specific intent for the voice-based request, including capturing metadata. A user interaction routine determines a user interaction parameter associated with the virtual assistant based upon the voice-based request from the user. A user sentiment analysis routine determines a user satisfaction parameter associated with the virtual assistant based upon the voice-based request from the user. The controller responds in real-time to the voice-based request based upon the user satisfaction parameter and the user interaction parameter that are associated with the virtual assistant.

8. The system of claim 1 , further comprising the instruction set being executable to determine the domain associated with the voice-based request; wherein the controller is arranged to disengage from the voice-based request from the user when the domain associated with the voice-based request is not recognized.
9. A method for user support in a vehicle, comprising:
receiving, via a microphone, a voice-based request from a user;
employing a virtual assistant to determine a user interaction in real time and to determine a specific intent for the voice-based request, including capturing metadata;
determining a user interaction parameter associated with the virtual assistant based upon the voice-based request from the user, wherein the user interaction parameter is determined based upon a quantity of dialogue iterations, a system latency time, and a recognition of a domain to determine the specific intent for the voice-based request;
determining a user satisfaction parameter associated with the virtual assistant based upon the voice-based request from the user; and
responding in real-time to the voice-based request based upon the user satisfaction parameter and the user interaction parameter associated with the virtual assistant; and
transferring the voice-based request from the user to a second assistant based upon the user satisfaction parameter and the user interaction parameter;
