[email protected] ABSTRACT The IPA currently does not specify how to represent prenasalization, preglottalization, or preaspiration. We first review some current transcription practices, and phonetic and phonological literature bearing on the unitary status of prenasalized, preglottalized and preaspirated segments. We then propose that the IPA adopt superscript diacritics placed before a base symbol for these three phenomena. We also suggest how the current IPA Diacritics chart can be modified to allow these diacritics to be fit within the chart. 2 1 Introduction The IPA provides a variety of diacritics which can be added to base symbols in various positions: above ([a͂ ]), below ([n̥ ]), through ([ɫ]), superscript after ([tʰ]), or centered after ([a˞]). Currently, IPA diacritics which modify base symbols are never shown preceding them; the only diacritics which precede are the stress marks, i.e. primary ([ˈ]) and secondary ([ˌ]) stress. Yet, in practice, superscript diacritics are often used preceding base symbols; specifically, they are often used to notate prenasalization, preglottalization and preaspiration. These terms are very common in phonetics and phonology, each having thousands of Google hits. However, none of these phonetic phenomena is included on the IPA chart or mentioned in Part I of the Handbook of the International Phonetic Association (IPA 1999), and thus there is currently no guidance given to users about transcribing them. In this note we review these phenomena, and propose that the Association’s alphabet include superscript diacritics preceding the base symbol for prenasalization, preglottalization and preaspiration, in accord with one common way of transcribing them.
