Abstract:
1. A method of providing a seamless hybrid computer and human call service comprising: interacting during a telephone call by a caller with at least one of a human agent and a Voice User Interface, the Voice User Interface comprising: a text to speech system by which one of text entered by the human agent and computer generated text is converted to speech by the text to speech system and transmitted by the caller; a morphing transformation library containing pre-computed voice parameters unique to agents affiliated with the Voice User Interface; and a switching subsystem for transferring handling of the call between the Voice User Interface and the human agent, wherein when a call is initially handled by verbal interaction with the human agent, the agent's voice is heard by the caller, and wherein when the call is transferred from the human agent to the Voice User Interface, the text to speech system communicates an agent's text entered by the human agent or a computer's text to the caller in a computer's voice using pre-computed voice transformation parameters unique to the agent who transferred the call and thereby rendering the computer's voice derived from the text to speech system similar to the agent's voice, and wherein when a call is initially handled by the Voice User Interface, the text to speech system communicates with the caller in a computer's voice and when the call is transferred to the human agent an agent to computer transformation is applied to the agent's voice using the pre-computed parameters according to the agent ID in the morphing transformation library thereby rendering the agent's voice similar to that of the computer's voice initially perceived by the caller.
