The Intelligibility of a Spelling-Regular English Accent

Regular English Pronunciation (REP) is an artificial accent of English designed to be more logically related to English spelling than modern naturally-occurring English accents. The REP pronunciation of words can be generated automatically with a set of just 200 rules and exceptions. These rules and exceptions have been measured to provide over 75% of standard pronunciations in running spoken English. This paper shows that the while the intelligibility of REP is a little worse than standard pronunciation on a challenging intelligibility task, it is significantly easier to comprehend than a matched control condition in which pronunciation changes are unrelated to spelling. The paper also shows that listeners improve in their ability to recognise REP over a short period of exposure. The results suggest that advocacy of regularised pronunciation has a role to play in the reform of English spelling.
