Transcription (linguistics)
Transcription in the linguistic sense is the systematic representation of spoken language in written form. The source can either be utterances (''speech'' or ''sign language'') or preexisting text in another writing system. Transcription should not be confused with translation, which means representing the meaning of text from a source-language in a target language, (e.g. ''Los Angeles'' (from source-language Spanish) means ''The Angels'' in the target language English); or with transliteration, which means representing the spelling of a text from one script to another. In the academic discipline of linguistics, transcription is an essential part of the methodologies of (among others) phonetics, conversation analysis, dialectology, and sociolinguistics. It also plays an important role for several subfields of speech technology. Common examples for transcriptions outside academia are the proceedings of a court hearing such as a criminal trial (by a court reporter) or a physicia ...

Transcription (biology)
Transcription is the process of copying a segment of DNA into RNA. The segments of DNA transcribed into RNA molecules that can encode proteins are said to produce messenger RNA (mRNA). Other segments of DNA are copied into RNA molecules called non-coding RNAs (ncRNAs). mRNA comprises only 1–3% of total RNA samples. Less than 2% of the human genome can be transcribed into mRNA ( Human genome#Coding vs. noncoding DNA), while at least 80% of mammalian genomic DNA can be actively transcribed (in one or more types of cells), with the majority of this 80% considered to be ncRNA. Both DNA and RNA are nucleic acids, which use base pairs of nucleotides as a complementary language. During transcription, a DNA sequence is read by an RNA polymerase, which produces a complementary, antiparallel RNA strand called a primary transcript. Transcription proceeds in the following general steps: # RNA polymerase, together with one or more general transcription factors, binds to promoter ...

Transcription Disc
Electrical transcriptions are special phonograph recordings made exclusively for radio broadcasting,Browne, Ray B. and Browne, Pat, Eds. (2001). ''The Guide to United States Popular Culture''. The University of Wisconsin Press. . P. 263. which were widely used during the "Golden Age of Radio". They provided material—from station-identification jingles and commercials to full-length programs—for use by local stations, which were affiliates of one of the radio networks. Physically, electrical transcriptions look much like long-playing records that were popular for decades. They differ from consumer-oriented recordings, however, in that they were "distributed to radio stations for the purpose of broadcast, and not for sale to the public.

Medical Transcription
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. History Medical transcription as it is currently known has existed since the beginning of the 20th century when standardization of medical records and data became critical to research. At that time, medical stenographers recorded medical information, taking doctors' dictation in shorthand. With the creation of audio recording devices, it became possible for physicians and their transcribers to work asynchronously. Over the years, transcription equipment has changed from manual typewriters, to electric typewriters, to word processors, and finally, , to computers. Storage ...

Transcription (software)
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. Transcription software, as with transcrip ...

Transcription (service)
A transcription service is a business service that converts speech (either live or recorded) into a written or electronic text document. Transcription services are often provided for business, legal, or medical purposes. The most common type of transcription is from a spoken-language source into text such as a computer file suitable for printing as a document such as a report. Common examples are the proceedings of a court hearing such as a criminal trial (by a court reporter) or a physician's recorded voice notes (medical transcription). Some transcription businesses can send staff to events, speeches, or seminars, who then convert the spoken content into text. Some companies also accept recorded speech, either on cassette, CD, VHS, or as sound files. For a transcription service, various individuals and organizations have different rates and methods of pricing. That can be per line, per word, per minute, or per hour, which differs from individual to individual and industry to ind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phonetic Transcription
Phonetic transcription (also known as phonetic script or phonetic notation) is the visual representation of speech sounds (or ''phones'') by means of symbols. The most common type of phonetic transcription uses a phonetic alphabet, such as the International Phonetic Alphabet. Versus orthography The pronunciation of words in all languages changes over time. However, their written forms (orthography) are often not modified to take account of such changes, and do not accurately represent the pronunciation. Words borrowed from other languages may retain the spelling from the original language, which may have a different system of correspondences between written symbols and speech sounds. Pronunciation can also vary greatly among dialects of a language. Standard orthography in some languages, such as English and Tibetan, is often irregular and makes it difficult to predict pronunciation from spelling. For example, the words ''bough'', ''chough'', ''cough'', ''though'' and ''through' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orthographic Transcription
Orthographic transcription is a transcription method that employs the standard spelling system of each target language.Hayes, Bruce (2011)Introductory Phonology John Wiley & Sons; , 9781444360134. "The term orthographic transcription simply means that the words are written down using the customary spelling system (orthography) of the language." For a better view of the examples shown in Hayes's book see Fromkin, Victoria (2000)''Linguistics: an introduction to linguistic theory'; Wiley-Blackwell; , 9780631197119thefreedictionary.com/Transcription citing Vinogradov, V. A., in ''The Great Soviet Encyclopedia'' (1979). Retrieved March 19, 2012. Examples of orthographic transcription are "Pushkin" and "Pouchkine", respectively the English and French orthographic transcriptions of the surname "Пу́шки ...

BBC Transcription Services
The BBC Transcription Services started life in the mid-1930s as the London Transcription Service to license BBC Radio programmes to overseas broadcasters who were authorised to broadcast the programmes for a set period, usually two or three years. The programmes sold to overseas broadcasters in this way covered every part of the BBC's output, including all types of music, drama, religious and children's programmes and comedy. It is now called BBC Radio International. Whilst the BBC destroyed most broadcast recordings it produced for its various outlets, BBC Transcription Services often retained their copy and many of the surviving radio programmes from the 1940s onwards owe their survival to the fact that Transcription Services issued the material. The original releases were in the form of 12-inch 78 rpm discs. Each of these discs contained no more than three or four minutes per side and so a radio operator would have needed to cue the start of many discs as the previous one f ...

Abortive Transcription
Abortive initiation, also known as abortive transcription, is an early process of genetic transcription in which RNA polymerase binds to a DNA promoter and enters into cycles of synthesis of short mRNA transcripts which are released before the transcription complex leaves the promoter. This process occurs in both eukaryotes and prokaryotes. Abortive initiation is typically studied in the T3 and T7 RNA polymerases in bacteriophages and in ''E. coli''. Overall process Abortive initiation occurs prior to promoter clearance. # RNA polymerase binds to promoter DNA to form an RNA polymerase-promoter ''closed'' complex # RNA polymerase then unwinds one turn of DNA surrounding the transcription start site to yield an RNA polymerase-promoter ''open'' complex # RNA polymerase enters into abortive cycles of synthesis and releases short RNA products (contains less than 10 nucleotides) # RNA polymerase escapes the promoter and enters into the elongation step of transcription Mechanism Aborti ...

Piano Transcription
In music, a reduction is an arrangement or transcription of an existing score or composition in which complexity is lessened to make analysis, performance, or practice easier or clearer; the number of parts may be reduced or rhythm may be simplified, such as through the use of block chords. Orchestral An orchestral reduction is a sheet music arrangement of a work originally for full symphony orchestra (such as a symphony, overture, or opera), rearranged for a single instrument (typically piano or organ), a smaller orchestra, or a chamber ensemble with or without a keyboard (e.g. a string quartet). A reduction for solo piano is sometimes called a piano reduction or ''piano score''. During opera rehearsals, a répétiteur (piano player) will typically read from a piano reduction of the opera. When a choir is learning a work scored for choir and full orchestra, the initial rehearsals will usually be done with a pianist playing a piano reduction of the orchestra part. Before t ...
