Sound

The open central unrounded vowel, or low central unrounded vowel, is a type of vowel sound, used in many spoken languages. While the International Phonetic Alphabet officially has no dedicated letter for this sound between front [a] and back [ɑ], it is normally written a. If precision is required, it can be specified by using diacritics, such as centralized ä or retracted , but this is not common.

Until recently, however, the letter a was officially used for the central vowel, and much of the existing body of work on phonetics reflects that. It is thus more common to use plain [a] for a central vowel, and to approximate an open front vowel, if needed, with [æ], officially near-open (near-low). Alternatively, Sinologists may use the unofficial symbol (small capital A). The IPA voted against officially adopting this symbol in 2011–2012.[1]

Limburgish dialect of Hamont has been reported to contrast open front, central and back unrounded vowels,[2] which is extremely unusual.

The IPA prefers terms "close" and "open" for vowels, and the name of the article follows this. However, a large number of linguists, perhaps a majority, prefer the terms "high" and "low".

  • Its vowel height is open, also known as low, which means the tongue is positioned as far as possible from the roof of the mouth – that is, as low as possible in the mouth.
  • Its vowel backness is central, which means the tongue is positioned halfway between a front vowel and a back vowel. This often subsumes open (low) front vowels, because the tongue does not have as much flexibility in positioning as it does for the close (high) vowels; the difference between an open front vowel and an open back vowel is equal to the difference between a close front and a close central vowel, or a close central and a close back vowel.
  • It is unrounded, which means that the lips are not rounded.

Occurrence[edit]

Most languages have some form of an unrounded open vowel. Because the IPA uses a for both front and central unrounded open vowels, it is not always clear whether a particular language uses the former or the latter.
