Open front unrounded vowel
From MedBib.com - Medicine & Nature
Where symbols appear in pairs, the one to the right
represents a rounded vowel.
The open front unrounded vowel is a type of vowel sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is a, and the equivalent X-SAMPA symbol is a.
This symbol is very frequently used for an open central unrounded vowel, and this usage is accepted by the International Phonetic Association.[citation needed] Since no language distinguishes front from central open vowels, a separate symbol is not considered necessary. If required, the difference may be specified with the central diacritic, [ä], or the retracted diacritic, [a̠]. Many Sinologists use an unofficial symbol [A] alternatively (see Obsolete and nonstandard symbols in the International Phonetic Alphabet).
Features
- Its vowel height is open, which means the tongue is positioned as far as possible from the roof of the mouth.
- Its vowel backness is front which means the tongue is positioned as far forward as possible in the mouth without creating a constriction that would be classified as a consonant. This subsumes central open vowels because the tongue does not have as much flexibility in positioning as it does for the close 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 mid vowel, or a close mid and a close back vowel.
- Its vowel roundedness is unrounded, which means that the lips are not rounded.
Occurrence
Most languages have some form of an unrounded open vowel. For languages that only have a single low vowel, the symbol for this vowel <a> may be used because it is the only low vowel whose symbol is part of the basic Latin alphabet. Whenever marked as such, the vowel is closer to a central [ä] than to a front [a].
