Do we need a symbol for a central open vowel?

Abstract

The present discussion re-opens an old issue that was ‘officially discussed’ in Kiel in 1989 but has not been offered for debate in the wider phonetic community. It is argued that there is a logical and practical gap in the present IPA vowel chart. The lack of a central open vowel is unsatisfactory, in particular because more languages have a single open vowel with an apparently more central than fronted or backed quality. Arguments and suggestions for a number of alternative solutions to the problem are presented for discussion.
