X-SAMPA [ ˈɛksˌsæmpə ] (Abbreviation for Extended Speech Assessment Methods Phonetic Alphabet [ ɪkˈstɛndɪd spiːtʃ əˈsɛsmənt ˌmɛθədz fəʊˈnɛtɪk ˈælfəbɛt ]) is a further development of SAMPA , a phonetic alphabet that can be represented by 7-bit ASCII . X-SAMPA was developed in 1995 by the British phonetician John C. Wells in order to bring the different SAMPA variants for different languages to a common denominator, as well as to be able to represent all characters that occur in the International Phonetic Alphabet . Despite the spread of Unicode for the purpose of creating and archiving print products, X-SAMPA is increasingly being used in phonetic and language technology contexts around the world, especially when it comes to the automatic processing of large amounts of transcriptions in local languages for statistical purposes, speech input / output To develop systems and to create lexicographic databases.
