A software tool for auditory and speech perception experimentation

Abstract

A computer program capable of supporting auditory and speech perception experimentation is described. Given a continuum of acoustic stimuli, the program (Paradigm) allows the user to present those stimuli under different, well-known psychophysical paradigms (simple identification, identification with a rating scale, 2IAX, ABX, AXB, and oddity task). For discrimination tests, both high uncertainty (roving designs) and minimal psychophysical uncertainty (fixed designs) procedures are available. All the relevant time intervals can be precisely specified, and feedback is also available. Response times can be measured as well. Furthermore, the program stores subjects' responses and provides summaries of experimental results for both individual subjects and groups. The program runs on Microsoft Windows (3.1 or 95) on personal computers equipped with any soundboard.
