jTRACE is a cross-platform Java reimplementation and extension of the TRACE model of spoken word recognition. TRACE (McClelland and Elman, 1986) is a three-layer interactive-activation model of speech perception that takes a pseudoacoustic input representation and accurately simulates many phenomena of human speech processing. The goals of the reimplementation are to provide a user-friendly version of the model that can run on any current computer platform, extend the model with graphing and scripting tools, and thus provide a tool that is powerful enough for intensive research while easy enough to use in a classroom setting. New features in jTRACE include simulation visualization, results graphing, powerful scripting, internal and external noise parameters, adjustable lexical and phonological characteristics, word recognition metrics, data exporting, and saving/archiving tools. A set of historically relevant simulations is bundled with the program. This feature is ideal for educational applications. Any simulation can be saved in a similar format, promoting sharing and replication. jTRACE was validated quantitatively against the original implementation by replicating key simulations reported in the literature. jTRACE can be downloaded freely from [Work supported by National Institute on Deafness and Other Communication Disorders.]
