Extract

At the 1989 Kiel Convention of the IPA a sub-group was established to draw up recommendations for the transcription of disordered speech. The report produced at the Convention appeared in print in Duckworth, Hardcastle, Allen and Ball (1990), being mainly a list of symbols, termed ‘extensions to the IPA’, or ‘extIPA’ for short. Examples of the use of the extIPA symbols are given in Ball (1991), Howard (1993) and Ball, Code, Rahilly and Hazlett (1994) among others, and Ball (1993) includes them at textbook level. Various changes and additions to the original set of symbols are reported in Bernhardt and Ball (1993). These changes mean, however, there is a need for a listing of the current set of symbols, preferably in as concise a form as possible. There was also felt to be a need for the symbol set to receive overt recognition from a relevant society, therefore this publication marks the official adoption of the extIPA symbols by the International Clinical Phonetics and Linguistics Association (ICPLA).
