Abstract

This paper introduces and illustrates the Extensions to the International Phonetic Alphabet (IPA) that have been recommended for the narrow transcription of disordered speech. The relationship between these Extensions and previous suggestions for transcribing atypical speech made by the Working Party for the Phonetic Representation of Disordered Speech (PRDS) is described. By including the transcription of aspects of connected speech such as voice quality, rate and intensity, and by permitting uncertainty in transcription to be indicated, the International Phonetic Association has sanctioned significant developments in transcription conventions that will be of use to many people concerned with the narrow transcription of speech.
