The procedure for modifying the alphabet or the chart is to propose the change in the Journal of the IPA. (See, for example, December 2008 on an open central unrounded vowel and August 2011 on central approximants.) Reactions to the proposal may be published in the same or subsequent issues of the Journal (as in August 2009 on the open central vowel). A formal proposal is then put to the Council of the IPA – which is elected by the membership – for further discussion and a formal vote.
