Klaus J. Kohler

Klaus J. Kohler ([ˈklaʊs ˈkoːlɐ]; born 1935 in Karlsruhe) is one of the leading German phoneticians.

After leaving school in 1954, Klaus Kohler studied English, French, German, and Phonetics at the universities of Heidelberg, Besançon/France, and Edinburgh/Scotland, obtaining degrees at the universities of Heidelberg and Edinburgh. His 1964 PhD thesis was entitled Aspects of the History of English Pronunciation in Scotland. He was lecturer at the university of Edinburgh from 1961 to 1966 and taught at the university of Bonn from 1966 to 1971. In 1971 followed his appointment to the newly created Chair of Phonetics in the Faculty of Arts of the University of Kiel, and to the directorship of an independent Department of Phonetics, subsequently founded in the same year. Kohler was Director of this Department until 2002.

Between 1971 and 2006, he carried out a large number of German Research Council (DFG) funded projects into segmental and prosodic sound structures of High and Low German, English, and French. From 1973 to 2005 he was the Editor of the Institute Work-in-Progress series Arbeitsberichte des Instituts für Phonetik der Universität Kiel (AIPUK). One of the international convention he organized was a 1989 meeting of the International Phonetic Association (IPA) to revise the international phonetic alphabet (known as the "Kiel Convention").

Kohler's research areas comprise prosody and intonation of German, development of the Kiel Intonation Model (KIM) and of prosodic labelling (PROLAB) on the basis of this model, as well as the implementation of this model in German text-to-speech synthesis.
