Integrated voice processing systems. Generalpurpose common computer platform voice processing systems described provide integrated voice processing functions, for example, voice messaging, call processing, interactive voice response and other systems typically only available in discrete systems. Industry standard computer databases and interfaces are used to create a dynamically modifiable voice processing system which is adaptable to perform to any customer specification. State vector architecture for the system described herein provide economic and efficient tailoring of voice processing functions for a wide variety of applications. Voice processing systems for interfacing voice transactions through a telecommunications line to a user comprise a general-purpose digital, computer common-platform adapted to communicate through the telecommunications line with an outside environment. A relational database interfaced to the general-purpose, digital computer for storing at least one object having a state that is modifiable by a vector protocol, thereby producing a voice transaction event that is output to the user through the telecommunications whereby the user activates the vector protocol through the telecommunications to act on the object and produce the voice transaction event, and an interface adapted to convert user commands input to the voice processing system through the telecommunications to activate the vector protocol and alter the object's state.
