A stenomask is a hand-held microphone A microphone, colloquially called a mic or mike (), is a transducer that converts sound into an electrical signal. Microphones are used in many applications such as telephones, hearing aids, public address systems for concert halls and public ... built into a padded, sound-proof enclosure that fits over the speaker's mouth or nose and mouth. Some lightweight versions may be fitted with an elastic neck strap to hold them in place while freeing the user's hands for other tasks. The purpose of a stenomask is to allow a person to speak without being heard by other people, and to keep background noise away from the microphone. A stenomask is useful for speech recognition applications, because it allows voice transcription (linguistics), transcription in noisy environments. Perhaps more importantly, a stenomask silences the user's voice so that it does not interfere with the surrounding environment such as a court or a classroom. The user ...

Court Reporting
A court reporter, court stenographer, or shorthand reporter is a person whose occupation is to capture the live testimony in proceedings using a stenographic machine, thereby transforming the proceedings into an official certified transcript by nature of their training, certification, and usually licensure. This can include courtroom hearings and trials, depositions and discoveries, sworn statements, and more. United States The court reporter in some states is a notary by virtue of their state licensing, and a notary public is authorized to administer oaths to witnesses and who certifies that their transcript of the proceedings is a verbatim account of what was said—unlike a court recorder, who only operates recording machinery and sends the audio files for transcription over the internet, or a voice writer, who uses voice-to-text software. Many states require a court reporter to hold a certification obtained through the National Court Reporters Association; some oth ...

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 ...

Sound Baffle
A sound baffle is a construction or device which reduces the strength (level) of airborne sound. Sound baffles are a fundamental tool of noise mitigation, the practice of minimizing noise pollution or reverberation. An important type of sound baffle is the noise barrier constructed along highways to reduce sound levels at properties in the vicinity. Sound baffles are also applied to walls and ceilings in building interiors to absorb sound energy and thus lessen reverberation. Highway noise barriers The technology for accurate prediction of the effects of noise barrier design using a computer model to analyze roadway noise has been available since the early 1970s. The earliest published scientific design of a noise barrier may have occurred in Santa Clara County, California in 1970 for a section of the Foothill Expressway in Los Altos, California. The county used a computer model to predict the effects of sound propagation from roadways, with variables consisting of vehicle ...

Oxygen Mask
An oxygen mask provides a method to transfer breathing oxygen gas from a storage tank to the lungs. Oxygen masks may cover only the nose and mouth (oral nasal mask) or the entire face (full-face mask). They may be made of plastic, silicone, or rubber. In certain circumstances, oxygen may be delivered via a nasal cannula instead of a mask. Medical plastic oxygen masks Medical plastic oxygen masks are used primarily by medical care providers for oxygen therapy because they are disposable and so reduce cleaning costs and infection risks. Mask design can determine accuracy of oxygen delivered with many various medical situations requiring treatment with oxygen. Oxygen is naturally occurring in room air at 21% and higher percentages are often essential in medical treatment. Oxygen in these higher percentages is classified as a drug with too much oxygen being potentially harmful to a patient's health, resulting in oxygen dependence over time, and in extreme circumstances patient blindn ...

Horace Webb
Quintus Horatius Flaccus (; 8 December 65 – 27 November 8 BC), known in the English-speaking world as Horace (), was the leading Roman lyric poet during the time of Augustus (also known as Octavian). The rhetorician Quintilian regarded his ''Odes'' as just about the only Latin lyrics worth reading: "He can be lofty sometimes, yet he is also full of charm and grace, versatile in his figures, and felicitously daring in his choice of words."Quintilian 10.1.96. The only other lyrical poet Quintilian thought comparable with Horace was the now obscure poet/metrical theorist, Caesius Bassus (R. Tarrant, ''Ancient Receptions of Horace'', 280) Horace also crafted elegant hexameter verses (''Satires'' and '' Epistles'') and caustic iambic poetry ('' Epodes''). The hexameters are amusing yet serious works, friendly in tone, leading the ancient satirist Persius to comment: "as his friend laughs, Horace slyly puts his finger on his every fault; once let in, he plays about the heartstrin ...

Headset (audio)
Headsets connect over a telephone or to a computer, allowing the user to speak and listen while keeping both hands free. They are commonly used in customer service and technical support centers, where employees can converse with customers while typing information into a computer. Also common among computer gamers are headsets, which will let them talk with each other and hear others, as well as use their keyboards and mice to play the game. Types Telephone headsets generally use loudspeakers with a narrower frequency range than those also used for entertainment. Stereo computer headsets, on the other hand, use 32-ohm speakers with a broader frequency range. Mono and stereo Headsets are available in single-earpiece and double-earpiece designs. Double-earpiece headsets may support stereo sound or use the same monaural audio channel for both ears. Single-earpiece headsets free up one ear, allowing better awareness of surroundings. Telephone headsets are monaural, even for doubl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Darth Vader
Darth Vader is a fictional character in the ''Star Wars'' franchise. The character is the central antagonist of the original trilogy and, as Anakin Skywalker, is one of the main protagonists in the prequel trilogy. ''Star Wars'' creator George Lucas has collectively referred to the first six episodic films of the franchise as "the tragedy of Darth Vader". He has become one of the most iconic villains in popular culture, and has been listed among the greatest villains and fictional characters ever. His masked face is one of the most iconic character designs of all time. Originally a slave on Tatooine, Anakin Skywalker is a Jedi prophesied to bring balance to the Force. He is lured to the dark side of the Force by Chancellor Sheev Palpatine / Darth Sidious and becomes a Sith Lord, assuming the title of Darth Vader.

Microphone
A microphone, colloquially called a mic or mike (), is a transducer that converts sound into an electrical signal. Microphones are used in many applications such as telephones, hearing aids, public address systems for concert halls and public events, motion picture production, live and recorded audio engineering, sound recording, two-way radios, megaphones, and radio and television broadcasting. They are also used in computers for recording voice, speech recognition, VoIP, and for other purposes such as ultrasonic sensors or knock sensors. Several types of microphone are used today, which employ different methods to convert the air pressure variations of a sound wave to an electrical signal. The most common are the dynamic microphone, which uses a coil of wire suspended in a magnetic field; the condenser microphone, which uses the vibrating diaphragm as a capacitor plate; and the contact microphone, which uses a crystal of piezoelectric material. Microphones typically n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stenotype
A steno machine, stenotype machine, shorthand machine, stenograph or steno writer is a specialized chorded keyboard or typewriter used by stenographers for shorthand use. In order to pass the United States Registered Professional Reporter test, a trained court reporter or closed captioner must write speeds of approximately 180, 200, and 225 words per minute (wpm) at very high accuracy in the categories of literary, jury charge, and testimony, respectively. Some stenographers can reach 300 words per minute. The website of the California Official Court Reporters Association (COCRA) gives the official record for American English as 375 wpm. The stenotype keyboard has far fewer keys than a conventional alphanumeric keyboard. Multiple keys are pressed simultaneously (known as "chording" or "stroking") to spell out whole syllables, words, and phrases with a single hand motion. This system makes realtime transcription practical for court reporting and live closed captioning. Because ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
