![]() International adoptionĪfter the phonetic alphabet was developed by the International Civil Aviation company history below it was adopted by many other international and national organizations, including the International Telecommunication Union ITU, the International Maritime Organization IMO, the United States Federal Government as Federal standards 1037C: Glossary of Telecommunications Terms, and its successors ANSI T1.523-2001 and ATIS Telecom Glossary ATIS-0100523.2019, using the English spellings "Alpha" and "Juliet", the United States Department of Defense using standard spellings, the Federal Aviation Administration FAA, and the International Amateur Radio Union IARU, the American Radio Relay League ARRL, the Association of Public-Safety Communications Officials-International APCO and by numerous military organizations such(a) as the North Atlantic Treaty Organization NATO and the now-defunct Southeast Asia Treaty Organization SEATO. To change one word involves reconsideration of the whole alphabet to ensure that the change reported to clear one confusion does non itself introduce others. One of the firmest conclusions reached was that it was not practical to make an isolated change to clear confusion between one pair of letters. ![]() It is required that has been prepared only after the almost exhaustive tests on a scientific basis by several nations. Strict adherence to the prescribed spellings-including the apparently misspelled "Alfa" and "Juliett"-is known in order to avoid the problems of confusion that the code is intentional to overcome. Numbers are read off as English digits, but the pronunciations of three, four, five, nine and thousand are modified. The 26 code words are as follows: Alfa, Bravo, Charlie, Delta, Echo, Foxtrot, Golf, Hotel, India, Juliett, Kilo, Lima, Mike, November, Oscar, Papa, Quebec, Romeo, Sierra, Tango, Uniform, Victor, Whiskey, X-ray, Yankee, Zulu. Spelling alphabets are often inaccurately called "phonetic alphabets", but they form not indicate phonetics and cannot function as phonetic transcription systems like the International Phonetic Alphabet. The words were chosen to be accessible to speakers of French and Spanish in addition to English the spellings of a couple of code words were changed to facilitate their use. In 1956, NATO modified the then-current vintage of code words used by the International Civil Aviation Organization ICAO this adjusting then became the international standard when it was accepted by the ICAO that year as well as by the International Telecommunication Union ITU a few years later. ![]() The particular code words varied, as some seemingly distinct words were found to be ineffective in real-life conditions. To make the code, a series of international agencies assigned 26 code words acrophonically to the letters of the English alphabet, so that the designation for letters as well as numbers would be as distinct as possible so as to be easily understood by those who exchanged voice messages by radio or telephone, regardless of language differences or the classification of the connection. a ITU phonetic alphabet as living as figure code is a rarely used variant that differs in the script words for digits. Today the only parts of the JANAP WWII-era alphabet still in use include “Charlie,” “Mike,” “Victor” and “X-Ray.The International Radiotelephony Spelling Alphabet, usually known as a NATO phonetic alphabet, NATO spelling alphabet, ICAO phonetic alphabet or ICAO spelling alphabet, is the nearly widely used radiotelephone spelling alphabet. The alphabet was adopted in 1941, and in use until 1957, which was the year it was officially discontinued by the IRSA. In World War II, the United States military used a modified version of the Joint Army/Navy Phonetic Alphabet (JANAP). The military alphabet was used during World War II The current version, also known as the NATO alphabet and used by the nations of NATO was approved in the year 1957. The first official version of the military alphabet was approved in 1927, although a version was used as early as 1913. This helps avoid confusion between words that have similar sounds. The IRSA is used to spell out words and letters via radio.
