Voice Recognition
Software Helping Dyslexics by Ian
Austen ANDREW GANAT graduated from high
school in May and is looking forward to college in the fall. While that is an
important milestone in anyone's life, reaching it is especially sweet for Mr.
Ganat, 18. In the second grade, he was found to have the learning disability dyslexia.
"My overall problem is memorizing the spelling
of words," said Mr. Ganat, who is from Norwalk, Conn. "I can get all the letters
down but I can't make them into the word."
Specialized schooling including five years as a boarder at the Gow School
near Buffalo, which specializes in teaching students with language-based learning
problems certainly helped take Mr. Ganat to the threshold of college. But
for the last three years he has found another way to boost both his grades and
his outlook. Mr. Ganat is one of a number of dyslexics, both students and adults,
using voice recognition software to transfer their ideas into print.
"It's made my grades improve," Mr. Ganat said of
the software. "I didn't think I was getting the right grades before. I'm not a
dumb kid, so it was frustrating. But now I've kind of found a way to be even with
everyone else." Marshall H. Raskind, a
learning disabilities researcher at the Frostig Center in Pasadena, Calif., said
that voice recognition software could make a significant difference for many people
with dyslexia. "It is a great equalizer," he said. "When someone feels they can
express themselves in writing it can have positive implications for self- esteem.
One guy told me, `For the first time in my life I can write love letters.' "
After studying the use of the software by dyslexic
students for 10 years and publishing four joint papers on his findings, Dr. Raskind
has concluded that speech recognition not only allows dyslexics to communicate
more efficiently but may even help them overcome their condition.
"Children who wrote using speech recognition technology for as little as 10 1/2
hours showed significant improvement in reading, decoding, spelling and comprehension,"
Dr. Raskind said. "We were blown away by this. The results are preliminary. But
it is very encouraging." The use of voice
recognition software by dyslexic students has largely taken software companies
by surprise. "The focus is around driving larger business opportunities for voice
recognition," said David Nahamoo, senior manager for human language technologies
at IBM. (news/quote) Research. "But the last time I saw the letters from dyslexic
users, I thought, it's wonderful." While
software companies have focused on developing voice recognition for common uses
like controlling cell phones, making computers more accessible to non-typists
and hands- free control of gadgets in automobiles, the technology is slowly making
its way into a range of applications for people with disabilities.
Harnessed by determined researchers in what is almost
an underground movement, it has helped people with impairments ranging from paralysis
to repetitive stress injury that make typing painful or impossible. People with
dyslexia are now beneficiaries, too. Dyslexia
is a broad term for language disabilities that cause a person to have trouble
understanding written words, sentences or paragraphs. The International Dyslexia
Association estimates that dyslexia is the most common source of reading, writing
and spelling problems. Dyslexic students tend to have separate vocabularies for
writing and speaking: even if they are highly articulate, they draw on a strictly
limited selection of words when writing. When they were able to dictate their
papers and examination responses to a computer, Dr. Raskind found, the students
exploited their full language capabilities.
So far, the use of voice recognition by dyslexics is very limited. Dr. Raskind
said he had been unprepared for the opposition he encountered from some people,
including teachers. "I don't want to make
it sound like a panacea," he said of the software. "It can be very, very frustrating
for some students. But many people view assistive technologies in general as a
crutch, a way of avoiding a problem. It's weird: it's like seeing someone with
a white cane and saying, `Rip that cane out of their hands and let them do it
themselves.' " Robert Follansbee, co-director
of Speaking to Write, a project financed by the Department of Education that is
examining the use of voice recognition in secondary schools, said: "Special educators
are hip to it now. They get it. But often regular educators don't understand it.
The comment I've heard many times from teachers is `They'll never learn to write.'
" Dr. Raskind first got the idea of having
dyslexics rely on computers when he headed the learning disabilities program at
California State University at Northridge. In 1991 he began developing a long-term
research program with Eleanor L. Higgins, a senior research associate at the Frostig
Center, a research and treatment center for people with learning disabilities.
Together they focused on dyslexic California State students who were dictating
reports and exam answers by using Dragon Dictate, a precursor to the popular L&H
Dragon Naturally Speaking software. "Often
they'll be able to talk it out fine but they have difficulty translating it to
the printed page," Dr. Raskind said. Dragon
Dictate's performance with what was then state-of-the-art computers was, Dr. Raskind
recalls, not brilliant in technical terms. But the results generated by the 29
Northridge students who used it were impressive. "You could no longer differentiate
their writing when they used speech recognition from writing by students without
learning difficulties," he said. "The quality of their writing was far superior"
to what it had been. So were the students'
marks. One factor was what might be called the 25-cent word effect. "If you use
bigger words, a bigger vocabulary, you get graded higher," Dr. Raskind said.
It was some of Dr. Raskind's own subjects who
first suggested that the software might even be having an effect on their reading
or writing skills. "After using it over the course of a year, they started saying
things like, `You know, I think my reading and spelling are getting better,' "
he said. Two joint studies he has done since then tracking students ages 9 to
18 seem to confirm their impressions.
Dr. Raskind believes that the explanation may be fairly straightforward. "You
say a word and then you see a word," he said of the programs. "That's an age-old
approach that's used with kids who have dyslexia."
Mr. Ganat, the college-bound 18- year-old, began working on voice recognition
in the 10th grade. Although he struggled at first, his main problem now, as he
tells it, is dealing with others' disbelief. Using the IBM. speech recognition
software Via Voice, he writes the first draft of most of his papers and even the
answers to some examinations. Then he pastes his work into Microsoft (news/quote)
Word for revisions and corrections. This
year he wrote a 15-page history paper on the construction of the Pentagon. "My
history teacher didn't believe I wrote it at first because it had no spelling
mistakes," said Mr. Ganat, who plans to attend Johnson & Wales University
in Providence, R.I. "Now I feel like I'm ready to write at a college level."
Since switching to the software, Mr. Ganat said,
his reading has improved "but my spelling is not up to par."
Certainly Mr. Ganat's mother, Elaine, has noticed a striking improvement in the
e-mail he has sent home. "Before you had to figure out where the vowels went,"
she said. "Now you can read them." Brett
Jeremy didn't have the advantage of voice recognition in dealing with his dyslexia
in school. He got through college by painstakingly writing and rewriting papers
in longhand and then turning them over to a girlfriend "who could word process
at 80 words per minute." After becoming vice president for production at Native
Kjalii Foods, a maker of salsa and tortilla chips in San Francisco, it took "days
of frustration and pressure" to produce a five-page technical document because
he constantly transposed letters within words.
About four years ago Mr. Jeremy tried an early version of Dragon. "I thought it
was the stupidest thing in the world," he said. "It took forever and I didn't
understand it." But he gave a subsequent version of the software a chance a year
later and became a believer. "Now I can push out a very technical five-page document
in less than a day," he said. That's not
to say the program is perfect. "Try dictating a word like `dewatering granulator,'
" he said. "The software just doesn't even try."
Paradoxically, some of the technological advances being made as IBM. and L&H
chase a wider market may work against the interests of dyslexics. Early voice
recognition programs demanded that users utter each word slowly and deliberately.
The results, after a bit of delay, appeared on computer screens one word at a
time. Current software, however, demands that users speak at a normal, conversational
pace, with the words quickly flooding the screen.
"It depends on the student, but for some it can be too much information, too fast,"
Dr. Raskind said. He is one of many researchers who think that the answer may
be a return to the past and are studying the features of voice recognition software
to find which are most effective for dyslexic users.
The goal is to develop a stripped- down version of the software that won't overwhelm
the user a feeling that even the fully literate consumer knows only too
well. With thanks to the excellent and
