      Many laboratories designed to assess vocal tract function are still dependent on FM tape recorders, strip chart recorders, and analog oscilloscopes. Data reduction is often a tedious process requiring time-consuming manual measurement routines. The present report describes the components of a high-speed computer system for real-time data acquisition and display, stimulus control, and automated analysis. The acquisition and computational performance of this system is exemplified in a discussion of two special-purpose software applications, including (a) speech aerodynamics and (b) orofacial force physiology.
