Research

Dr. Oliver Wendt’s research investigates the efficacy of augmentative and alternative communication (AAC) strategies including graphic symbols, mobile technologies, and speech-generating devices for individuals on the autism spectrum that present with little or no functional speech. Dr. Wendt specializes in single-subject experimental designs and meta-analyses of these studies. He is first editor of the textbook “Assistive Technology. Principles and Applications for Communication Disorders and Special Education” (Emerald Publishing). Dr. Wendt serves on the editorial boards of the American Journal of Speech-Language Pathology, Augmentative and Alternative Communication, Evidence-based Communication Assessment and Intervention, and Evidence-based Practice Briefs. He is the 2005 recipient of the Editor Award for the Most Significant Research Article in Augmentative and Alternative Communication (together with Schlosser, Angermeier, & Shetty). In 2013, Dr. Wendt received the Purdue Focus Award for outstanding contributions to disability accessibility.

In addition, Dr. Wendt is co-founder of an AAC software company by the name of SPEAK MODalities LLC, which is dedicated to providing the best evidence-based AAC solutions for developing communication, speech, and language skills in individuals with autism and/or severe communication disorders. The following video shows some of the innovative technologies developed through the partnership between Dr. Wendt’s AAC research lab and SPEAK MODalities:
