Speech Tracking was first introduced as an auditory training technique by DeFilippo and Scott (1978). The KTH computer-assisted method of Speech Tracking uses an algorithm created at the Royal Institute of Technology in Sweden (KTH) by Gnospelius and Spens (1992). This was modified in 2007 into a computerized program by the Rehabilitation Engineering Research Center (RERC) on Hearing Enhancement at Gallaudet University in collaboration with Dr. Harry Levitt and Chris Oden at Advanced Hearing Concepts, and Geoff Plant at MED-EL. Evidence-based citation on the use of KTH Speech Tracking is reported by Bernstein et al (2012).
Funding for the development of the software and instructional video on KTH Speech Tracking was provided by the National Institute on Disability and Rehabilitation Research, U.S. Department of Education, Grant #H133E030006 (RERC on Hearing Enhancement). The contents of the webpage were developed under a grant from the National Institute on Disability, Independent Living, and Rehabilitation Research ,Grant # 90RE5020.
