The Effectiveness of Oral Expression through the use of Continuous Speech Recognition Technology in Supporting the Written Composition of Postsecondary Students with Learning Disabilities

What it is: A 2002 Virginia Tech study that compared three ways of writing for postsecondary students with learning disabilities: a human transcriber, continuous speech recognition, and unassisted keyboarding. It measured essay quality, length and rate of production.
How much weight it carries: A university thesis rather than a journal article, so it has not had journal peer review. The sample is students with learning disabilities, and the recognition software is from 2002, older than current engines. It is one of the few controlled comparisons of dictated and typed essays that we found.

Facts taken from this source

In a 2002 dissertation, postsecondary students with learning disabilities in written expression wrote significantly higher quality essays, at a faster rate, with continuous speech recognition than by keyboarding without help.
“Analysis of the data revealed that students with learning disabilities in the area of written expression wrote significantly higher quality essays at a faster rate using the transcription and speech recognition modes of writing than they did using the keyboarding method of writing.” (Abstract)
In the same 2002 dissertation, essay length did not differ significantly among the three ways of writing.
“There was no significant difference in the length of essays across the three treatment groups.” (Abstract)
In the same 2002 study, essay length did not differ significantly between speech recognition, human transcription and keyboarding.
