Menu-based, speech actuated system with speak-ahead capability
Abstract:
An interactive voice response system has speak-ahead capabilities similar to type-ahead IVR systems by determining multi-level grammars for responses. Preferably, an existing IVR application is processed automatically to generate a multi-level grammar database that can then be used in recognizing multi-level responses by a user.
