This paper presents a new interactive speech processing environment designed for Microsoft Window platforms. It will be shown that how an integrated speech processing environment was made following Windows Interface Design Guidelines. The environment integrates many traditional time and frequency domain analysis algorithms as well as basic functions like recording, listening and labeling. Choosing Component Object Model (COM) as the architectural framework assures high maintainability, scripting capability and further expandability of this environment. Extensive use of the system in laboratory has shown how this interactive environment improves users performance in their every day speech processing tasks.
