Vowel transcription systems: an Australian perspective

Transcription is an essential clinical tool for speech-language pathologists as it provides a permanent written record of communicative behaviour and forms an important source of data for analysis, interpretation, decision making, and dissemination. One of the responsibilities in speech-language pathology is to faithfully capture the speech production characteristics of clinical populations so that informed management decisions may be made. Notation systems that are appropriately suited for this purpose are mandatory. In Australia today, the conventional phonemic transcription system was first described over 60 years ago. However, an alternative to this traditional system has more recently been proposed by Harrington, Cox and Evans (HCE). This paper details the HCE system and argues its advantage as a clinical tool for speech-language pathologists in Australia. This new system provides a more accurate phonetically oriented foundation against which atypical vowel production can be assessed. It is further argued that the HCE system can form the basis for narrower phonetic examination and has pedagogical value in the description of Standard Australian English.
