Enhanced ASL Dictionary app available

RIT/NTID-developed dictionary used all over the world

An enhanced version of the ASL Video Dictionary and Inflection Guide, created by Rochester Institute of Technology’s National Technical Institute for the Deaf, now is available for iPhones and Android phones.

The ASL Video Dictionary and Inflection Guide has been a popular educational tool used worldwide, with examples of 2,700 signs and 650 sentences. It is used by those learning American Sign Language as well as deaf students learning English.

“It fills a critical need in that it presents signs in sentence-level context to allow viewers to see how the signs change to convey different meanings,” said Geoff Poor, project director.

The iOS app is available in the Apple App store for $1.99, and the Android app is available in the Google Play store for $1.99.



The Web app is free for members of the RIT community at

And the ASL Video Dictionary and Inflection Guide CD remains for sale for $49.95, with discounts for educational purposes. Visit “site licenses” at dictionary, and available by subscription to others for $39.99 per year.

Poor credits RIT’s Production Services department, especially Web/IT Services Web Developer/Programmer Harry Groover, Web Designer Megan Bastian and Assistant Director Raman Bhalla for their work on this project.
