Abstract
A computerized method is provided for evaluating performance of a virtual service agent. The method includes automatically generating at least one persona for impersonating a virtual customer by inputting a select demographic profile into a trained large language model (LLM). The method also includes generating (i) a list of questions for the virtual service agent for completing at least one task and (ii) a simulated context comprising at least one of mood or attitude of the virtual customer at beginning of the interaction. The method further includes enabling the virtual customer to interact with the virtual service agent to complete the task via multiple simulated dialogue turns involving the list of questions and the simulated context and evaluating the performance of the virtual service agent based on the dialogue turns.
