Voice Computing
Voice computing is the discipline that develops hardware or software to process voice inputs. It spans many other fields including human-computer interaction, conversational computing, linguistics, natural language processing, automatic speech recognition, speech synthesis, audio engineering, digital signal processing, cloud computing, data science, ethics, law, and information security. Voice computing has become increasingly significant in modern times, especially with the advent of smart speakers like the Amazon Echo and Google Assistant, a shift towards serverless computing, and improved accuracy of speech recognition and text-to-speech models. History Voice computing has a rich history. First, scientists like Wolfgang Kempelen started to build speech machines to produce the earliest synthetic speech sounds. This led to further work by Thomas Edison to record audio with dictation machines and play it back in corporate settings. In the 1950s-1960s there were primitive attem ...

Speech Recognition
Speech recognition is an interdisciplinary subfield of computer science and computational linguistics that develops methodologies and technologies that enable the recognition and translation of spoken language into text by computers with the main benefit of searchability. It is also known as automatic speech recognition (ASR), computer speech recognition or speech to text (STT). It incorporates knowledge and research in the computer science, linguistics and computer engineering fields. The reverse process is speech synthesis. Some speech recognition systems require "training" (also called "enrollment") where an individual speaker reads text or isolated vocabulary into the system. The system analyzes the person's specific voice and uses it to fine-tune the recognition of that person's speech, resulting in increased accuracy. Systems that do not use training are called "speaker-independent" systems. Systems that use training are called "speaker dependent". Speech recognition ...

National Security Agency
The National Security Agency (NSA) is a national-level intelligence agency of the United States Department of Defense, under the authority of the Director of National Intelligence (DNI). The NSA is responsible for global monitoring, collection, and processing of information and data for foreign and domestic intelligence and counterintelligence purposes, specializing in a discipline known as signals intelligence (SIGINT). The NSA is also tasked with the protection of U.S. communications networks and information systems. The NSA relies on a variety of measures to accomplish its mission, the majority of which are clandestine. The existence of the NSA was not revealed until 1975. The NSA has roughly 32,000 employees. Originating as a unit to decipher coded communications in World War II, it was officially formed as the NSA by President Harry S. Truman in 1952. Between then and the end of the Cold War, it became the largest of the U.S. intelligence organizations in terms of pers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harpy
In Greek mythology and Roman mythology, a harpy (plural harpies, , ; lat, harpȳia) is a half-human and half-bird personification of storm winds. They feature in Homeric poems. Descriptions They were generally depicted as birds with the heads of maidens, faces pale with hunger and long claws on their hands. Roman and Byzantine writers detailed their ugliness. Pottery art depicting the harpies featured beautiful women with wings. Ovid described them as human-vultures. Hesiod To Hesiod, they were imagined as fair-locked and winged maidens, who flew as fast as the wind. Aeschylus But even as early as the time of Aeschylus, they are described as ugly creatures with wings, and later writers carry their notions of the harpies so far as to represent them as most disgusting monsters. The Pythian priestess of Apollo recounted the appearance of the harpies in the following lines: Virgil Hyginus Functions and abodes The harpies seem originally to have been wind spirits (perso ...

IBM Shoebox
The IBM Shoebox was a 1961 IBM computer that was able to perform mathematical functions and perform speech recognition. It recognized 16 spoken words, including the digits 0 through 9. It was developed by William C. Dersch in the Advanced Systems Development Division Laboratory at IBM History It was displayed at the IBM Pavilion during the 1962 Seattle World's Fair. It was approximately the size and shape of a standard American shoebox. It had a display of ten small lamp lights labeled with the digits 0 through 9 and an attached microphone. Speaking the name of the digit into the microphone would cause the appropriate digit lamp to light. Inside the box were a power supply, three analog audio filters and some (presumably) Diode-Resistor-Logic circuitry. The design allowed for the recognition of each digit name “Zero”, “One”, Two” … “Nine” and its front, middle, and ending sound. (Sometimes no middle). And that each sound was high pitched, middle pitched or low p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Audrey
Audrey () is an English feminine given name. It is the Anglo-Norman form of the Anglo-Saxon name ''Æðelþryð'', composed of the elements '' æðel'' "noble" and ''þryð'' "strength". The Anglo-Norman form of the name was applied to Saint Audrey (d. 679), also known by the historical form of her name as Saint Æthelthryth. The same name also survived into the modern period in its Anglo-Saxon form, as ''Etheldred'', e.g. Etheldred Benett (1776–1845). In the 17th century, the name of ''Saint Audrey'' gave rise to the adjective ''tawdry'' "cheap and pretentious; cheaply adorned". The lace necklaces sold to pilgrims to Saint Audrey fell out of fashion in the 17th century, and so tawdry was reinterpreted as meaning cheap or vulgar. As a consequence, use of the name declined, but it was revived in the 19th century. Popularity of the name in the United States peaked in the interbellum period, but it fell below rank 100 in popularity by 1940 and was not frequently given in the later ...

Dictation Machine
A dictation machine is a sound recording device most commonly used to record speech for playback or to be typed into print. It includes digital voice recorders and tape recorder. The name "Dictaphone" is a trademark of the company of the same name, but it has also become a common term for all dictation machines, as a genericized trademark. History Alexander Graham Bell and his two associates took Edison's tinfoil phonograph and modified it considerably to make it reproduce sound from wax instead of tinfoil. They began their work at Bell's Volta Laboratory in Washington, D.C.In 1879, and continued until they were granted basic patents in 1886 for recording in wax.Newville, Leslie JDevelopment of the Phonograph at Alexander Graham Bell's Volta Laboratory United States National Museum Bulletin, United States National Museum and the Museum of History and Technology, Washington, D.C., 1959, No. 218, Paper 5, pp.69-79.

Thomas Edison
Thomas Alva Edison (February 11, 1847October 18, 1931) was an American inventor and businessman. He developed many devices in fields such as electric power generation, mass communication, sound recording, and motion pictures. These inventions, which include the phonograph, the motion picture camera, and early versions of the electric light bulb, have had a widespread impact on the modern industrialized world. He was one of the first inventors to apply the principles of organized science and teamwork to the process of invention, working with many researchers and employees. He established the first industrial research laboratory. Edison was raised in the American Midwest. Early in his career he worked as a telegraph operator, which inspired some of his earliest inventions. In 1876, he established his first laboratory facility in Menlo Park, New Jersey, where many of his early inventions were developed. He later established a botanical laboratory in Fort Myers, Florida, in co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wolfgang Von Kempelen
Johann Wolfgang Ritter von Kempelen de Pázmánd ( hu, Kempelen Farkas; 23 January 1734 – 26 March 1804) was a Hungarian author and inventor, known for his chess-playing "automaton" hoax The Turk and for his speaking machine. Personal life Von Kempelen was born in Pressburg, today's Bratislava (Slovakia), part of the Kingdom of Hungary within the Habsburg Empire, the last child of Engelbert Kempelen (1680–1761), and Anna Theresa Spindler. Contrary to some reports, he did not hold the title of "Ritter" or "Baron." This misconception may stem from historical confusion with one of his older brothers, Johannes Nepomuk Joseph, who attained the rank of general within the Habsburg Empire, and who was granted the title ''Kempelen von Pázmánd'' after purchasing a former Jesuit estate in Pázmánd, a village south of Budapest. Von Kempelen studied law and philosophy in Pressburg, and attended the Academy in Győr, Vienna and Rome, but mathematics and physics also interested hi ...

Hidden Markov Models
A hidden Markov model (HMM) is a statistical Markov model in which the system being modeled is assumed to be a Markov process — call it X — with unobservable ("''hidden''") states. As part of the definition, HMM requires that there be an observable process Y whose outcomes are "influenced" by the outcomes of X in a known way. Since X cannot be observed directly, the goal is to learn about X by observing Y. HMM has an additional requirement that the outcome of Y at time t=t_0 must be "influenced" exclusively by the outcome of X at t=t_0 and that the outcomes of X and Y at t handwriting recognition, handwriting, gesture recognition, part-of-speech tagging, musical score following, partial discharges and bioinformatics. Definition Let X_n and Y_n be discrete-time stochastic processes and n\geq 1. The pair (X_n,Y_n) is a ''hidden Markov model'' if * X_n is a Markov process whose behavior is not directly observable ("hidden"); * \operatorname\bigl(Y_n \in A ...
