What Exactly is Speech
Recognition?
•
Speech Recognition is the process of
translating spoken words into text
words on the computer.
•
Through a speech recognition
program/application, the computer is
able to process words you say and turn
them into text on the screen just as if
you had typed them on the keyboard.
How Speech Recognition
Can Benefit Students
Dictation has the potential to
improve the writing performance of
students with learning disabilities by
removing the barriers created by the
difficulties with mechanics.
Speech Recognition
To support quality of writing
Removes the motor demands of writing
Written Productivity Profile = difficulty with both
writing & keyboarding
More restrictive
Requires quiet environment, consistency is more
important than articulation
Typically not used for note taking, but for homework
and independent written work
Speech Recognition
To support access
For students who are not able to physically
access the keyboard and mouse
Requires quiet environment, consistency is more
important than articulation
Most likely require a program that provides full
control of the computer (i.e. Dragon Naturally
Speaking)
Benefits and Challenges

Cognitive Skills
•
Proficiency in the use of speech
recognition requires good levels of
concentration, memory and other cognitive
skills. In order for a student to use speech
recognition independently, good cognitive
skills are essential for memorizing
commands as well as making effective use
of correction strategies.

Consistency of Speech
Consistency of speech and pronunciation is one of the most
important prerequisites for success in using speech
recognition. As long as any user is able to say words and
phrases in the same or similar manner each time, speech
recognition programs can learn to recognize individual
patterns of speech. way each time.
The user's voice quality, such as volume and pitch, and
breath control should also be taken into account.
The bottom line in terms of speech, is that it should be
intelligible and consistent, but it need not be perfect in terms
of articulation, pronunciation and quality.

Reading and Writing
Students who read at a third-grade level or
higher, and who achieve scores of 1 on most
of the items on the evaluation form, have
extremely high potential for using speech
recognition independently. In addition those
students who are able to accurately isolate
word recognition errors and make
corrections/edit their work will do well with
speech-recognition.

Speech Recognition: MS Office 2003
Open MS Word→ Tools → Speech
•
This enables the language bar for both
speech-to-text and text-to-speech options
•
You will be guided through training needed to
create a user voice profile (15 minutes)
•
You will need a microphone
•
Can dictate directly into MS Office, not other
applications
Speech Recognition –
Vista and Windows 7
Built into the Operating System
Open Speech Recognition by clicking the Start
button , clicking Control Panel, clicking Ease
of Access, and then clicking Speech
Recognition.
Click Set up microphone, follow the
instructions in the wizard.
Dictate into almost any application (i.e. word
processing, internet).

Success vs. Effort
•
An extremely important point when
considering the potential use of speech
recognition by students with learning and
physical challenges, is that speech
recognition is not a plug-and-play
technology, but a complex technological
solution requiring extensive training,
patience, perseverance and support.
Not Appropriate for
Everyone
•
Speech recognition will not work for all
students, and it is important to go through an
initial evaluation in order to determine if the
student has the potential to cope.
A positive note about the future of speech
recognition, is that since it is becoming more
accurate and the technology is improving,
we will find that more and more students are
able to use this program in the future.
