. The first version of SAMPA was the union of the sets of phoneme codes for Danish, Dutch, English, French, German and Italian; later versions extended SAMPA to cover other European languages. Since SAMPA is based on phoneme inventories, each SAMPA table is valid only in the language it was created for. In order to make this

support for IPA symbols becomes more widespread, the necessity for a separate, computer-readable system for representing the IPA in ASCII decreases. However, text input relies on specific keyboard encodings or input devices. For this reason, SAMPA and X-SAMPA are still widely used in computational phonetics and in speech technology.
