Modified cassette recorder. To record a lecture, own thoughts,
ideas, notes etc.
Desktop dictation system.
To allow audio cassette playback with the aid of a foot
A device used in conjunction with OCR software. The
printed document is scanned and converted into electronic
text, which can then be displayed on screen as recognizable
Standalone reading aids are integrate a scanner, optical
character recognition (OCR) software and speech software in
a single machine, working without a separate PC.
Refreshable Braille display. An electronic
tactile device which is placed under the computer keyboard.
A line of cells, that move up and down to represent a line
of text on the computer screen,enables the user to read the
contents of the computer screen in Braille.
Electronic Notetaker. A portable computer
with a Braille or QWERTY keyboard and synthetic speech. Some
models have an integrated Braille display.
Braille embosser. Embosses Braille output
from a computer by punching dots onto paper. It connects to
a computer in the same way as a text printer.
Speech recognition applications that have
emerged over the last few years include voice dialing (e.g.,
"Call home"), call routing (e.g., "I would like
to make a collect call"), appliance control and content-based
spoken audio search (e.g. find a podcast where particular words
were spoken), simple data entry (e.g., entering a credit card
number), preparation of structured documents (e.g., a radiology
report), speech-to-text processing (text for Open Document word
processors, emails...); in the cockpit of some military fast
jets (where it is generally referred to as Direct Voice Input
- DVI -).
Voice recognition, or better, speaker recognition is a related
process that attempts to identify the person speaking, as opposed
to what is being said
A screen magnifier,
low vision software that interfaces with a computer's graphical
output to present enlarged screen content. It is a type of
assistive technology suitable for visually impaired people
with some functional vision; visually impaired people with
little or no functional vision usually use a screen reader.
Optical character recognition, usually abbreviated
to OCR, is the mechanical or electronic translation
of images of handwritten, typewritten or printed text (usually
captured by a scanner) into machine-editable text.
OCR is a field of research in pattern recognition,
artificial intelligence and machine vision. Though academic
research in the field continues, the focus on OCR has shifted
to implementation of proven techniques. Optical character
recognition (using optical techniques such as mirrors
and lenses) and digital character recognition (using scanners
and computer algorithms) were originally considered separate
fields. Because very few applications survive that use true
optical techniques, the OCR term has now been broadened to
include digital image processing as well.
Early systems required training (the provision of known samples
of each character) to read a specific font. "Intelligent"
systems with a high degree of recognition accuracy for most
fonts are now common. Some systems are even capable of reproducing
formatted output that closely approximates the original scanned
page including images, columns and other non-textual components.
