Abstract

The Automated Phonetic Transcription Grading Tool (APTgt) is an online Learning Management System (LMS) that facilitates the comparison of phonetic transcriptions for instruction and clinical training purposes. It uses an embedded IPA graphical keyboard for transcription input. A custom edit distance algorithm aligns transcriptions in an intuitive way and then calculates differences quantitatively. This allows for objective scoring of transcriptions of even severely impaired productions, which may be difficult to score via traditional comparison methods. APTgt also includes support for comparing narrow phonetic transcriptions with diacritics.
