Voice Recognition and Voice Output

Suaste 1
Voice Recognition and Voice Output in today’s generation has really grown and is very
help full for many reasons. For entertainment usage, Professional work, Security purposes, and
even to communication for disabled people. The most common device most of have is in our
phones. But how this all started through many years of developing such a creatable thing to make
our lives today and our future much feasible.
The beginning of this invention started in January 1, 1874 when
“Alexander Graham Bell proves that frequency harmonics from an electrical
signal can be divided. This eventually leads to the digitization of speech.” Than
in 1936: AT&T's Bell Labs produced the first electronic speech synthesizer called
the Voder (Dudley, Riesz and Watkins). This machine was demonstrated in the
1939 World Fairs by experts that used a keyboard and foot pedals to play the
machine and emit speech” – The Voice Recognition
Companies and systems which include: Covox, Dragon systems, Speech Works, Charles
Schwab, Bell South, IBM, Microsoft and Apple all throughout the years have developed and
created and invested ways so all this can be possible of this invention. - The Voice Recognition

Like Mentioned before Voice Recognition is used everywhere today the first example is
for Security measures. Big enterprises, which use these systems so they can protect their values,
important documents etc… The way these system works is the system recognizes the voice print
in order to access to a safe or safe area. –Voice Security.
Another example is the when you call a credit card company and an automated machine
answers and It gives options that direct you to the right department and when it asks you
questions it lets you speak and answer the questions by which than it will understand you. –call

When it comes to Professional Work a good example is Pilots. The Art of Aviation has
changed drastically Pilots have started to train and accommodate more on computerized system.
Voice Flight Systems is an example of how Pilots can enter wave points to get them to their
destinations. It’s easy, time saving and easy to correct errors. According to the site all they have
to so is enter the wave points, and in the screen it will appear what they just spoke. On its
webpage it has a demonstration on how their product the VFS 101 system can set up the flight
plan in about 15 seconds. Than after the pilot finishes entering the wave points the system reads
back to you the instructions that the Pilots told it to do. –Voice Flight.

On the other hand there is voice input and upon research voice output has helped more
with people and disabilities who can’t communicate so they have this machine that can do the
talk for them. One disease Autism and on its web page at the top it mentions Why use a voice put
communication device and this why:
“For over 40 years voice output devices have been used to help individuals with
developmental and acquired disabilities to communicate successfully. Voice
output devices offer tremendous promise in helping nonverbal individuals with
autism overcome their unique communication barriers. The auditory output
provides one more sensory feedback to help the child develop his receptive and
expressive language skills. Other advantages of voice-output communication
devices are explained below.”

Another example is Stephan Hawking besides being a brilliant man he had disease was
slowly leaving him paralyzed but with the creation of his wheel chair with a computer they
developed a machine that could help him communicate. Pretty much he used his mind to control
his screen and be able to communicate that’s pretty cool and I think a big step in the future AI.
In Conclusion It has been mentioned about Voice Recognition and Voice Output In
which in every decade it has been advancing and growing. The history and Alexander Graham
Bell, AT&T and other companies’ contributed to making this possible. Also how voice
recognition helps with security, piloting and people who are disabled and cannot speak and how
voice output device has helped them communicate better.
