ARPABET

Phonetic notation

ARPABET is a set of phonetic transcription codes developed by Advanced Research Projects Agency (ARPA) as a part of their Speech Understanding Research project in the 1970s. It represents phonemes and allophones of General American English with distinct sequences of ASCII characters. Two systems, one representing each segment with one character and the other with one or two (case-insensitive), were devised, the latter being far more widely adopted.
