|
|
|
|
|
|
|
|
|
|
<P> Let's look at Linux-based voice recognition software from the perspective of China.
|
|
It would behoove Linux computer makers anyway to begin manufacturing their
|
|
computers in China, because China offers a low-cost method of manufacturing and
|
|
provides them with a large market for their hardware which can also be exported
|
|
to other important markets around the world.
|
|
|
|
<P> Linux computers have the capacity to accommodate voice recognition
|
|
systems, such as IBM ViaVoice. This is especially advantageous to Chinese
|
|
speakers because both Mandarin and Cantonese are very complex in the written
|
|
form, so documents could be more easily produced through voice recognition
|
|
software running on a Linux platform. Using a keyboard is next to impossible
|
|
for Chinese languages because so many characters are involved in typing a
|
|
document.
|
|
|
|
<P> Other languages will also benefit from using voice recognition software
|
|
for purposes of speed. Hands-busy, eyes-busy professionals can benefit
|
|
greatly from voice recognition so they don't have to use a mouse and keyboard
|
|
to document their findings. Voice-activated, easily-used telephone systems
|
|
will benefit all walks of life. Anyone driving a car will find voice
|
|
recognition a much more effective way of manipulating a vehicle and
|
|
communicating from the vehicle.
|
|
<P> The health-care market alone may justify the Linux based voice
|
|
recognition project. Health-care services are the largest expense of the
|
|
Group of Ten nations, and it is the fastest growing sector as well.
|
|
Health-care workers would benefit from using their voices to document
|
|
describing the treatments of patients. Voice recognition allows them a
|
|
hands-free environment in which to analyze, treat and write about particular
|
|
cases easily and quickly.
|
|
<P> Electronically connected medical devices via wireless
|
|
LAN can benefit:
|
|
<UL>
|
|
<LI> ...Hospital administration staff
|
|
<UL>
|
|
<LI> Improve the usage efficiency of resources
|
|
<LI> Achieve standardized, quality patient management
|
|
<LI> Dramatically reduce data recording (transcription) errors
|
|
<LI> Lower costs
|
|
<LI> Make any room a telemetry room on demand (that is, do laboratory
|
|
measurements in any room regardless of where the central equipment is located)
|
|
</UL>
|
|
<LI> ...Medical staff
|
|
<UL>
|
|
<LI> Be empowered with a 24/7 complete set of vital-sign data
|
|
<LI> Have more time for hands-on care
|
|
<LI> See changes in patient status immediately to enable quicker responses
|
|
</UL>
|
|
</UL>
|
|
|
|
|
|
<P> In this life sciences field, the simplicity, reliability and low cost of
|
|
Linux for servers, tablets, embedded devices and desktops is paramount.
|
|
Only about 10% of the documents in the health-care field in the USA are
|
|
produced electronically due to the cumbersome and unreliable nature of the
|
|
Windows environment. 30% of the cost of health-care is a direct result of
|
|
manual creation of the documents and many of the malpractice cases are also
|
|
due to the imprecision of transcriptions of manually scribbled medical
|
|
records and directives, as anybody who looks at a prescription can attest.
|
|
|
|
<P> Obviously, the market for these new technologies exists. What remains
|
|
is for a hungry company with aggressive sales people to tap into that market.
|
|
Once those sales people get the technology distributed, the needs of many
|
|
will be met and a new mass market will open up that Microsoft isn't filling:
|
|
assistive technology (AT). Actually, the field already exists but needs to
|
|
be expanded to include both physically disabled and functionally disabled.
|
|
<P> Yes, voice recognition offers great promise for the future. However, it
|
|
isn't perfect and needs to be improved. One improvement could use lip
|
|
reading to bolster its accuracy.
|
|
Still another is multi-tonal voice input. Another is directional
|
|
microphones. Every generation of voice recognition software will improve as
|
|
the hardware for Linux gets bigger and stronger.
