Abstract
A Voice User Interface is provided for interactively responding in a synthesized voice to a call from a human caller, a Text to Speech system by which text entered by an agent and interactive data are converted to synthesized speech, a morphing transformation library containing pre-computed voice transformation parameters unique to each agent affiliated with the VUI, and a switching system for transferring handling of the call between the VUI and the agent. The human agent's verbal interaction with the caller is performed in the agent's natural voice. Text transmitted by an agent to a caller and interactive data is in a synthesized voice created using the pre-computed transformation parameters corresponding to the agent's ID selected from the morphing transformation library. All speech presented to a caller is presented in approximately the same unique voice as initially presented when the call is established, thereby permitting an aurally seamless phone call, as perceived by the caller.
