The Model BEP XI is a multi-function system designed to acquire standardized measures of the speech production and hearing subsystems. It consists of: 1) HPM's proprietary "BEP for Windows" software* that runs on a user-supplied "host computer" and allows the user to focus on the test subject, not the ancillary tasks of measurement; 2) a compact high speed data acquistion, control, and processing unit that interfaces to the host computer through a simple serial port connection; 3) a "standardized", head-mounted microphone; 4) a "standardized" headphone set; 5) a compact power supply; and 6) a step by step manual for easy set-up and use. This compact and unobtrusive test instrument is positioned on a table in front of the subject. For speech tests, this precision instrument generates stimuli (visual and acoustic) and processes acoustic information from the microphone. Carefully selected short tasks permit isolation of many subsystems within the speech production system and allows rapid documentation of elemental and higher level performance capacities important to the execution of higher level speech tasks. During most measurement procedures, detection of the start and completion (for timed tests) of the test/data acquisition are automated for objectivity and accuracy. Record and playback tape deck interfaces are provided. The module also provides computer controlled acoustical stimuli to a headset for hearing performance tests.
