Abstract
Interactive voice response systems (IVRS, IVR System) are currently used in abundance as interfaces at a wide variety of support centers, call centers and other information retrieval centers. When a support center with IVRS is contacted by a caller, the caller is typically first presented with voice information from an interactive voice response unit (IVRU). The caller responses to the voice queries by providing input through the phone keypad. Each key input provided by the caller from the keypad is assigned with specific information in the database of the IVRS [1].
