Transcription refers to the process of converting sounds into letters or musical notes, or producing a copy of something in another medium, including:
Closed captioning (CC) is a form of subtitling, a process of displaying text on a television, video screen, or other visual display to provide additional or interpretive information, where the viewer is given the choice of whether the text is displayed. Closed captions are typically used as a transcription of the audio portion of a program as it occurs, sometimes including descriptions of non-speech elements. Other uses have included providing a textual alternative language translation of a presentation's primary audio language that is usually burned-in to the video and unselectable.
An audio tape recorder, also known as a tape deck, tape player or tape machine or simply a tape recorder, is a sound recording and reproduction device that records and plays back sounds usually using magnetic tape for storage. In its present-day form, it records a fluctuating signal by moving the tape across a tape head that polarizes the magnetic domains in the tape in proportion to the audio signal. Tape-recording devices include the reel-to-reel tape deck and the cassette deck, which uses a cassette for storage.
Transcription in the linguistic sense is the systematic representation of spoken language in written form. The source can either be utterances or preexisting text in another writing system.
Digital Compact Cassette (DCC) is a magnetic tape sound recording format introduced by Philips and Matsushita Electric in late 1992 and marketed as the successor to the standard analog Compact Cassette. It was also a direct competitor to Sony's MiniDisc (MD), but neither format toppled the then-ubiquitous analog cassette despite their technical superiority, and DCC was discontinued in October 1996. Another competing format, the Digital Audio Tape (DAT), had by 1992 also failed to sell in large quantities to consumers, although it was popular as a professional digital audio storage format.
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 or a stenomask, 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.
The Microcassette is an audio storage medium, introduced by Olympus in 1969.
A transcript is a written record of spoken language. In court proceedings, a transcript is usually a record of all decisions of the judge, and the spoken arguments by the litigants' lawyers. A related term used in the United States is docket, not a full transcript. The transcript is expected to be an exact and unedited record of every spoken word, with each speaker indicated. Such a record was originally made by court stenographers who used a form of shorthand abbreviation to write as quickly as people spoke. Today, most court reporters use a specialized machine with a phonetic key system, typing a key or key combination for every sound a person utters. Many courts worldwide have now begun to use digital recording systems. The recordings are archived and are sent to court reporters or transcribers only when a transcript is requested. Many US transcripts are indexed by Deposition Source so that they may be searched by legal professionals via the Internet. Transcripts may be available publicly or to a restricted group of persons; a fee may be charged.
The Mini-Cassette, often written minicassette, is a magnetic tape audio cassette format introduced by Philips in 1967.
In music, transcription is the practice of notating a piece or a sound which was previously unnotated and/or unpopular as a written music, for example, a jazz improvisation or a video game soundtrack. When a musician is tasked with creating sheet music from a recording and they write down the notes that make up the piece in music notation, it is said that they created a musical transcription of that recording. Transcription may also mean rewriting a piece of music, either solo or ensemble, for another instrument or other instruments than which it was originally intended. The Beethoven Symphonies transcribed for solo piano by Franz Liszt are an example. Transcription in this sense is sometimes called arrangement, although strictly speaking transcriptions are faithful adaptations, whereas arrangements change significant aspects of the original piece.
Medical transcription, also known as MT, is an allied health profession dealing with the process of transcribing voice-recorded medical reports that are dictated by physicians, nurses and other healthcare practitioners. Medical reports can be voice files, notes taken during a lecture, or other spoken material. These are dictated over the phone or uploaded digitally via the Internet or through smart phone apps.
Subtitles are texts representing the contents of the audio in a film, television show, opera or other audiovisual media. Subtitles might provide a transcription or translation of spoken dialogue. Although naming conventions can vary, captions are subtitles that include written descriptions of other elements of the audio, like music or sound effects. Captions are thus especially helpful to people who are deaf or hard-of-hearing. Subtitles may also add information that is not present in the audio. Localizing subtitles provide cultural context to viewers. For example, a subtitle could be used to explain to an audience unfamiliar with sake that it is a type of Japanese wine. Lastly, subtitles are sometimes used for humor, as in Annie Hall, where subtitles show the characters' inner thoughts, which contradict what they were saying in the audio.
Real-time transcription is the general term for transcription by court reporters using real-time text technologies to deliver computer text screens within a few seconds of the words being spoken. Specialist software allows participants in court hearings or depositions to make notes in the text and highlight portions for future reference.
Oral history preservation is the field that deals with the care and upkeep of oral history materials, whatever format they may be in. Oral history is a method of historical documentation, using interviews with living survivors of the time being investigated. Oral history often touches on topics scarcely touched on by written documents, and by doing so, fills in the gaps of records that make up early historical documents.
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.
Transcription software assists in the conversion of human speech into a text transcript. Audio or video files can be transcribed manually or automatically. Transcriptionists can replay a recording several times in a transcription editor and type what they hear. By using transcription hot keys, the manual transcription can be accelerated, the sound filtered, equalized or have the tempo adjusted when the clarity is not great. With speech recognition technology, transcriptionists can automatically convert recordings to text transcripts by opening recordings in a PC and uploading them to a cloud for automatic transcription, or transcribe recordings in real-time by using digital dictation. Depending on quality of recordings, machine generated transcripts may still need to be manually verified. The accuracy rate of the automatic transcription depends on several factors such as background noises, speakers' distance to the microphone, and accents.
An audio typist is someone who specialises in typing text from a vocal source which they listen to. The original voice document is usually recorded onto microcassettes by someone dictating into a Dictaphone. The audio typist will have learnt to touch type at a high speed which means they can look at the monitor or keep an eye on a waiting area as they are typing because they do not need to look at the keyboard. A specialist player called a micro cassette transcriber (below) is used for playback of the cassettes to maximise the typing speed.
The transcription machine is a special purpose machine which is used for word or voice processing. This special device manages audio video recording to transcribe them into written or hard copy form. So transcription machines are combination of transcribers and dictation machines.
Voice writing is a transcription method used for court reporting, medical transcription, CART, and closed captioning. Using voice writing, a court reporter speaks directly into a stenomask or speech silencer, a hand-held mask containing one or two microphones, and voice-dampening materials. As the reporter repeats the testimony into the recorder, the mask prevents the reporter from being heard during the testimony.
Otter.ai, Inc. is an American transcription software company based in Mountain View, California. The company develops speech to text transcription applications using artificial intelligence and machine learning. Its software, called Otter, shows captions for live speakers, and generates written transcriptions of speech.
