Obsolete and nonstandard symbols in the International Phonetic Alphabet


Obsolete and nonstandard symbols in the International Phonetic Alphabet

The International Phonetic Alphabet (IPA) possess a variety of obsolete and nonstandard symbols. Throughout the history of the IPA, characters representing phonetic values have been modified or completely replaced. An example is ‹ɷ› for standard [ʊ]. Several symbols indicating secondary articulation have been dropped altogether, with the idea that such things should be indicated with diacritics: ʮ for z̩ʷ is one. In addition, the rare voiceless implosive series ƥ ƭ ƈ ƙ ʠ has been dropped.

Other characters have been added in for specific phonemes which do not possess a specific symbol in the IPA. Sinologists have used ‹ɿ› to represent [z̩], a vowel which represents the i in hanzi (see Pinyin).

There are also unsupported symbols from local traditions that find their way into publications that otherwise use the standard IPA. This is especially common with affricates such as ƛ, and many Americanist symbols.

While the IPA does not itself have a set of capital letters (the ones that look like capitals are actually small capitals), many languages have adopted symbols from the IPA as part of their orthographies, and in such cases they have invented capital variants of these. This is especially common in Africa. An example is Kabiyé of northern Togo, which has Ɔ Ɛ Ŋ Ɣ Ʃ (capital ʃ). Other pseudo-IPA capitals supported by Unicode are Ɓ/Ƃ Ƈ Ɗ/Ƌ Ə/Ǝ Ɠ Ħ Ɯ Ɲ Ɵ Ʈ Ʊ Ʋ Ʒ.

Capital letters are also used as cover symbols in phonotactic descriptions: C=Consonant, V=Vowel, etc.

This list does not include commonplace extensions of the IPA, such as doubling a symbol for a greater degree of a feature ([aːː] extra-long [a], [ˈˈa] extra stress, [kʰʰ] strongly aspirated [k], and [a˞˞] extra-rhotic [a]), nor superscripting for a lesser degree of a feature ([ᵑɡ] slightly prenasalized [ɡ], [ᵗs] slightly affricated [s], and [ᵊ] epenthetic schwa). The asterisk, as in [k*] for the fortis stop of Korean, is the convention the IPA uses when it has no symbol for a phone or feature.

or Ø slashed 0 or uppercase slashed O null initial Usually used in phonology to mean "no sound values." However, in Chinese linguistics, some scholars considered it as "weak" glottal stop or something similar as sound value of the "existent" first consonant of syllables started by a vowel (e.g. ān in Tiān'ānmén), and this opinion can be connected with ㅇ (ieung) in hangul. can be confusing with close-mid front rounded vowel [ø].
