VOICE RECOGNITION: INTO THE FUTURE
Many newspapers, magazines, and technology demonstrations are featuring voice recognition as the wave of the future. But, is voice recognition really new?
HISTORICAL PERSPECTIVES ON VOICE RECOGNITION
People have been able to recognize each other’s voices since language first began. You need only to watch the face of a cat or dog when its owner speaks to know that the animal has heard and recognized the voice. Call centers and other kinds of businesses have been using a type of voice (speech) recognition for years.
Think for a moment, though, how exciting it would be to speak to your computer and have it understand what you said. Then, it would format what you said into what you need – a litter, a report, a table, a memo, or whatever, all with your voice telling you computer what to do. Is this really possible?
SPEECH RECOGNITION IN ITS INFANCY
While Bell Laboratories of Lucent Technologies created the first speech recognizer in 1952, the first speech recognition capability for PCs was finally developed in the 80s. The world’s first discrete speech dictation system was developed by Dragon Systems in 1990. Following that innovation was the world’s first commercially available software-only dictation system.[1]
In 1997, Jim and Janet Baker excited the speech recognition arena with the first dictation software to handle continuous speech. The spotlight focused on Naturally Speaking, another Dragon Systems’ product.[2]
VOICE RECOGNITION MARCHES ON
The technology movement had begun in earnest. Several companies jumped into the race to capture the market and produce software capable of higher and higher feats of accuracy. Software and portable device manufacturers came out with new programs and devices. Companies such as Sony, Norcom, Olympus, Dragon Systems, Lernout & Hauspie, and IDM, to name a few, began to find this field exciting.[3] Philips, Grover Industries, and others followed the thrill of voice recognition development with hardware and software utilities. Fore example, Grover Industries’ Web-TalkIt is an easy-to-use voice command and control utility for you default Web browser. Just say the Website you wish to visit and Web-TalkIt will go to the URL address.
USER OF VOICE RECOGNITION
Large mail order and customer service companies as well as utilities, banks, airlines, stockbrokers, manufacturers, and couriers are some of the major users of voice recognition. Customers or clients can use these voice recognition systems to obtain information, service, or to order products without human contact in most instances. Adding natural language processing to speech recognition gives us an entirely new user interface, notes Michael K. Miller of PC Magazine.[4]
Voice recognition programs are enabling many physically challenged persons to use their computers more efficiently and effectively. Adrian Clifton, the inspiration for Adrian’s Closet, which produces a line of clothing for young people with various disabilities, is beginning to use a voice-activated computer. He cannot use his hands, but he is able to enter invoices into files with is voice-activated computer.[5]
Financial traders, lawyers, and physicians are using voice recognition software. Pat Higgerty, a lawyer who cannot type, firmly believes in voice recognition technology. Higgerty creates most of his own documents and enjoys preparing a document while the client is in the office, printing it, and having the client sign the document before he or she leaves the office. Higgerty emphasizes that proper training on how to use the technology is a necessity for the 98 percent accuracy that he wants to attain.[6]
Physicians are finding voice recognition ideal for dictating chart notes after patient sessions. They say they often get more accurate notes because they can say more than if they were writing charts by hand.
More and more applications will be developed and more people will avail themselves of voice recognition technology as it is perfected and as accuracy levels improve above the 95-98 percent level.
TAKING IT ONE STEP FURTHER INTO THE FUTURE
What does the future hold for voice recognition technology? Forecasters say the sky is the limit. Computers ill probably arrive loaded with voice recognition software; you will be able to access the internet quickly, and you will be able to go from link to link just by saying what topic you want to request. Innovative software and equipment will make the lives of the blind, the deaf, and others with different physical difficulties more efficient by enabling them to access their computers without using their hands.
Some new processors can zoom through the math used in speech recognition making it possible to “train” the new computer to understand the user in less than give minutes. Software developers that harness the power of these new processors predict that speech recognition will be a standard PC feature by the end of the year.[7]
Is voice recognition in your future? Keep your ears sharp, watch for new developments, and you’ll probably be a voice recognition technology user soon!
