Abstract: A voice verification system (1) has a verification server layer (55) providing centralized verification for multiple service providers in geographically spread locations. Each service provider has an IVR (41) using a C++ DLL API (43) to communicate with a verification server (56, 57) via ISPs (45) and a switching system (50). Each API (43) dynamically determines an optimum ISP/server socket to minimize a verification cycle time. The switching system (50) has a router and two-stage switch combination with firewalls to provide optimum resilience in paths to the server (56, 57).

Abstract: A transaction processing system (1) has a central hub (2) which interconnects a high-speed database server (3), a voice processing server (5), and an interface server (6). The voice processing server (5) has a central processor and distributed processors including telephony interface circuits (5a), station interface circuits (5b), speech recognition DSPs (5c), and text-to-speech circuits (5d). The server (5) distributes processing in such a way that a user can make a telephone call to the system and convey data for a transaction by normal speech. The system uses this data to generate transaction records and the process transactions.
