Voice Recognition Systems *Works Cited Not Included About twenty years ago voice recognition systems were only see on the science fiction channel of the television and the viewer could only dream of the day when that technology would be possible. I know that when I was younger I would watch Star Trek and see Captain Kirk address the computer by talking to it, and not only did the computer understand his instructions, but it would flawlessly prefom the commands that were spoken. From the little that I knew before setting out on this project, I thought voice recognition systems were still primative, but I found that I was wrong. I have set out to discover the rapidly-changing world of voice recognition systems, and to ask the question, "What is vioce recognition systems and how is it currently used?". For many years people have wanted another avenue besides the keyboard to preform data processing. One of the first of these items is the barcode reader which is stronghly in use today. This product revelutionized the data processing industry but has a great number of limitaitons. The wave of the future in data processing is what is known as Voice recognition encoding. Voice recognition encoding has benn around for several years but not until recentallly has it become a viable solution. The main problem with voice recognition systems is that the technology was not available at a reasonable price until recently. A company located in Boston MA nade Dragon systems has created a product caleed NaturallySpeaking which has captured the market and offers a cost effective voice recognition swystem. This product is currently on the market and offers the ability to replace the cumbersome task of keyboarding w... ... middle of paper ... ... dictate a term paper. Disabled children and adults can activly and easily participate in our technilogical society. In our computerized world, the applications of NaturallySpeaking are endless. This program will also save people time. Our hands can be free, allowing us to complete other tasks. With the speed and accuracy of NaturallySpeaking, the user no longer has to spend time on spelling errors. With entrepreneurship growing rapidly in a world full of monopolies, smaller firms can now operate competitively . without having to hire additional people to perform tirival tasks. The increasingly rapid rate of new computer technology is quite astonishing. The NatruallySpaking Voice Recognition system has the ability to change the world just at the invention of the computer itself. The applicaitaions of this program are as endless as the imigination.
Here, actually, speech is decomposed into parameters like acoustic features such as fundamental frequency, the shape of the waveform, aperiodic energy etc and duration features related to contextual prosody. And the text is decomposed into various linguistic information. Then Hidden Markov Model or Deep Neural Networks can be used who will learn how to predict parameters such as acoustic features and duration features from the linguistic information of text data during the training phase.

AI has already been partially implemented in speech recognition software and customer services systems, but the systems can only work so well. "A number of products are available that feature AI, but they 're highly personalized” (Ramaswami 42). Products such as Dragon Speech are used for talking to a computer that translates speech to text. AI can only recognize what it is programmed to recognize currently though. Accents and speech tendencies can be foreign to a computer system. AI can work well in a limited atmosphere, but it can’t fully function in the real world because AI has limitations in what it can do. If AI’s speech recognition was fully capable though, it could be used for devastating possibilities. A suicide bomber may not have to risk their life anymore if they could place and activate a bomb through talking to an intelligent computer. The number of threats eliminated would never decrease then. Those efforts could do damage across the globe. “If A.I. machines can be capable of doing tasks originally done by humans, then the role of humans will change” (Implications of Artificial Intelligence). Terrorists would be able to learn from their previous mistakes and create more powerful and effective bombs. Replacing humans with machine intelligence impacts everybody, and usually in a negative
Several assistive listening devices can improve the communication ability of deaf children. According to IDEA, every child with a disability is entitled to have access to assistive technology (California Department of Education, 2004). The California Department of Education (2004) outlines IDEA’s definition of an assistive technology device. It explains that this device consists of “any item, piece of equipment or product system…that is used to increase, maintain, or improve functional capabilities of a child with a disability” (California Department of Education, 2004, p. 1).
Artificial intelligence system for speech recognition is the science and engineering of making intelligent machines, especially intelligent computer programs. Some of its applications are game playing, speech recognition, understanding natural language, computer vision, expert systems, robotics etc. It involves two basic ideas. First, it involves studying the thought processes of human beings. Second, it deals with representing those processes via machines (like computers, robots, etc.).
As our research into science and technology ever increases its seems inevitable that in the near future Artificial Intelligent machines will exist and become part of our everyday life such as we see with modern computers today.
Speech is the common basic way we communication with each other. The development of voice biometrics is one that emerged to allow a user to input their voice into a computer system. It is a growing technology which provides security in computers. A speech recognition system is designed to assist the user to complete what that person wants to say versus having a person transcribe it. The first step in voice recognition is for the user to be trained and produce an actual voice sample. Through this process sounds, words or phrases are converted in electrical signals and then they are turned into a coding process by the system. The goal of voice recognition is to understand the human spoken voice.
Imagine asking your computer to do something in the same way you would ask a friend to do it. Without having to memorize special commands that only it could understand. For computer scientists this has been an ambitious goal; that can further simplify computers. Artificial Intelligence, a system that can mimic human intelligence by performing task that usually only a human can do, usually has to use a form of natural language processing. Natural language processing, a sub-field of computer science and artificial intelligence, concerns the successfully interaction between a computer and a human. Currently one of the best examples of A.I.(Artificial Intelligence) is IBM 's Watson. A machine that gained popularity after appearing on the show
to modify an assigned baseline duration. In another approach large speech corpora are first analyzed by varying a number of possible control factors simultaneously to obtain duration models, such as an additive duration model by Kaiki [38], CARTs by Riley [3] and neural networks by Campbell [39]. The CARTs (classification and regression trees) proposed by Riley are data-driven models constructed automatically with the capability of self-configuration. The CART algorithm sorts instances in the learning data using binary yes/no questions about the attributes that the instances have. Starting at a root node, the CART algorithm builds a tree structure, selecting the best attribute and question to be asked at each node, in the process. The selection is based on what attribute and question will divide the learning data to give the
Speech sounds can be defined as those that belong to a language and convey meaning. While the distinction of such sounds from other auditory stimuli such as the slamming of a door comes easily, it is not immediately clear why this should be the case. It was initially thought that speech was processed in a phoneme-by-phoneme fashion; however, this theory became discredited due to the development of technology that produces spectrograms of speech. Research using spectrograms in an attempt to identify invariant features of formant frequency patterns for each phoneme have revealed several problems with this theory, including a lack of invariance in phoneme production, assimilation of phonemes, and the segmentation problem. An alternative theory was developed based on evidence of categorical perception of phonemes: Liberman’s Motor Theory of Speech Perception rests on the postulation that speech sounds are recognised through identification of how the sounds are produced. He proposed that as well as a general auditory processing module there is a separate module for speech recognition, which makes use of an internal model of articulatory gestures. However, while this theory initially appeared to account for some of the features of speech perception, it has since been subject to major criticism, and other models have been put forward, such as Massaro’s fuzzy logic model of perception.
Did your phone just ring? Or was that your computer notifying you of a new email? Since the Digital Revolution and the addition of digital electronics like the personal computer, software-based technology has always been an essential aspect of our lives. Something that would have taken up an entire classroom can now fit within the grasp of your hands thanks to the efforts of various computer scientists and engineers, making our lives much easier.
Instead, you will be able to talk naturally with speech, vision, and phrases that describe your objectives. The rest the computer will handle.
The computer evolution has been an amazing one. There have been astonishing achievements in the computer industry, which dates back almost 2000 years. The earliest existence of the computer dates back to the first century, but the electronic computer has only been around for over a half-century. Throughout the last 40 years computers have changed drastically. They have greatly impacted the American lifestyle. A computer can be found in nearly every business and one out of every two households (Hall, 156). Our Society relies critically on computers for almost all of their daily operations and processes. Only once in a lifetime will a new invention like the computer come about.
Phonetics and phonology have many possible applications both in theory and practice. Speech and speakers recognition and speakers synth...
...of input device. As I read and reflect on the vast and varieties of input devices, I now realised its importance of mankind as it brings enormous advantages to us. As a conclusion, input device is a part of computer hardware. It allows users to enter and give instruction to be able in process into the computer system. An input device has improved so much with time. It is substantial to say that people of this generation cannot live without those input device. Input device have not only made our life easier but it also helps in easing our financial and time. For example, the innovation of recent popular application, Wechat. This application is designed for those who are illiterate. People can just touch the ‘hold to talk’ button and says the word out. Then, release the button, the device will record down your voice and sent it out. This will be much easier for them.
