Routing Voice Commands to Virtual Assistants

Mechanisms are provided to implement an intelligent service broker for routing a voice command from a user to one or more virtual assistants based on each virtual assistant's capability to provide an accurate response. Responsive to receiving a voice command with a wake word associated with the intelligent service broker, the intelligent service broker identifies a subject or category of the voice command. Using the identified subject or category, the intelligent service broker selects one or more virtual assistants using a set of ranking values and a set of characteristics that indicate which ranking values to evaluate. The intelligent service broker sends the voice command to the identified virtual assistants and, responsive to receiving responses from more than one virtual assistant, identifies a confidence ranking for each of the responding virtual assistants and provides one or more of the responses based on a set of user configuration settings.
