Ever had trouble spelling something to someone? Learn the most widely used spelling alphabet!
The International Phonetic Alphabet can be pronounced and understood by those who transmit and receive voice messages by radio or telephone regardless of their native language, especially when the safety of navigation or persons is essential. The paramount reason is to ensure intelligibility of voice signals over telephone and radio links.
Primarily designed for military, aviation and maritime industries, it is also very useful in retail and information technology industries. It is used any times when saying the letters may cause confusion. For example, to transmit plane registration, radio beacons, serial numbers, model numbers, references, confirmation codes and credit agreements.
Spell any text using the complete NATO phonetic alphabet (also called ICAO, ITU), including letters and digits, with pronunciation in English and French as prescribed by the International Civil Aviation Organization (ICAO) and FAA.
