Using the Linkon system's low level direct driver interface, we have developed a fully-expandable, robust system for platform-independent collection of telephone speech data. Our object-oriented software libraries and intuitive GUI provide powerful tools with which even a novice user can efficiently generate complex applications. Using the system one can generate programs which range from simple single-user prompt/record demonstrations to robust SWITCHBOARD-type applications. This presentation will serve as an overview of the system and a tutorial on prototyping applications with the GUI.
