Improving lives through research based applications for the development of natural speech and language

Speak Modalities was formed to bring to the world the breakthrough work of Dr. Oliver Wendt, Professor of Speech, Language, and Hearing Sciences, and Special Education, director of the Augmentative and Alternative Communication (AAC) research lab at Purdue University. Dr. Wendt’s pioneering work provides evidence based methods and learning aids to improve the quality of communication for Autistic and individual impacted by language disabilities or delayed speech development. Dr. Wendt’s work has integrated leading science with tablet (iPad) technology to provide individuals a program with demonstrated outcomes.

The Speak Modalities team is addressing the constantly growing need for speech and language intervention in autism spectrum disorders. This communication disorder includes a “delay in, or total lack of, the development of spoken language” (American Psychiatric Association, 2000). With over 1 million children impacted by the Autism Spectrum Disorder, Dr. Wendt’s work is making a vital difference in the lives of many individuals everyday.

We are committed to bringing to market evidence based products which:

  • help individuals develop natural speech and language
  • grow with them as their needs and capabilities grow
  • expand their social horizons and
  • provide an entertaining experience in ways unique to them
