Speech compares with written language, [1] which may differ in its vocabulary, syntax, and phonetics from the spoken language, a situation called diglossia.
It consisted of IBM computer manuals, transcribed telephone conversations, and other texts, together containing over 4.5 million words of American English, annotated using both part-of-speech tagging and syntactic bracketing.
