The International Phonetic Alphabet (IPA) is an alphabetic system of phonetic notation based primarily on the Latin script. It was devised by the International Phonetic Association in the late 19th century as a standardized representation of speech sounds in written form. The IPA is used by lexicographers, foreign language students and teachers, linguists, speech–language pathologists, singers, actors, constructed language creators, and translators.
A vowel is a syllabic speech sound pronounced without any stricture in the vocal tract. Vowels are one of the two principal classes of speech sounds, the other being the consonant. Vowels vary in quality, in loudness and also in quantity (length). They are usually voiced and are closely involved in prosodic variation such as tone, intonation and stress.
The mid central vowel is a type of vowel sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ə⟩, a rotated lowercase letter e.
The open front unrounded vowel, or low front unrounded vowel, is a type of vowel sound used in some spoken languages. It is one of the eight primary cardinal vowels, not directly intended to correspond to a vowel sound of a specific language but rather to serve as a fundamental reference point in a phonetic measuring system.
The (near) open front rounded vowel, or (near) low front rounded vowel, is a type of vowel sound that has not been confirmed to be phonemic in any spoken language. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɶ⟩, and the equivalent X-SAMPA symbol is &. The letter ⟨ɶ⟩ is a small caps rendition of ⟨Œ⟩. ⟨œ⟩, the lowercase version of the ligature, is used for the open-mid front rounded vowel.
The close front unrounded vowel, or high front unrounded vowel, is a type of vowel sound that occurs in most spoken languages, represented in the International Phonetic Alphabet by the symbol i. It is similar to the vowel sound in the English word meet—and often called long-e in American English. Although in English this sound has additional length and is not normally pronounced as a pure vowel, some dialects have been reported to pronounce the phoneme as a pure sound. A pure sound is also heard in many other languages, such as French, in words like chic.
The close-mid front unrounded vowel, or high-mid 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 ⟨e⟩.
The close-mid central unrounded vowel, or high-mid central 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 ⟨ɘ⟩. This is a mirrored letter e and should not be confused with the schwa ⟨ə⟩, which is a turned e. It was added to the IPA in 1993; before that, this vowel was transcribed ⟨ë⟩. Certain older sources transcribe this vowel ⟨ɤ̈⟩.
The close-mid back rounded vowel, or high-mid back rounded vowel, is a type of vowel sound used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨o⟩.
The close-mid back unrounded vowel, or high-mid back unrounded vowel, is a type of vowel sound, used in some spoken languages. Its symbol in the International Phonetic Alphabet is ⟨ɤ⟩, called "ram's horns." This symbol is distinct from the symbol for the voiced velar fricative, ⟨ɣ⟩, which has a descender, but some texts use this symbol for the voiced velar fricative.
The open-mid back unrounded vowel or low-mid back 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 ⟨ʌ⟩, graphically a rotated lowercase "v", even though some vendors display it as a real turned v. Both the symbol and the sound are commonly referred to as a "wedge", "caret" or "hat". In transcriptions for English, this symbol is commonly used for the near-open central unrounded vowel and in transcriptions for Danish, it is used for the open back rounded vowel.
The open-mid back rounded vowel, or low-mid back rounded vowel, is a type of vowel sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɔ⟩. The IPA symbol is a turned letter c and both the symbol and the sound are commonly called "open-o". The name open-o represents the sound, in that it is like the sound represented by ⟨o⟩, the close-mid back rounded vowel, except it is more open. It also represents the symbol, which can be remembered as an o which has been "opened" by removing part of the closed circular shape.
The open-mid central unrounded vowel, or low-mid central 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 ⟨ɜ⟩. The IPA symbol is not the digit ⟨3⟩ or the Cyrillic small letter Ze (з). The symbol is instead a reversed Latinized variant of the lowercase epsilon, ɛ. The value was specified only in 1993; until then, it had been transcribed ⟨ɛ̈⟩.
The near-open central vowel, or near-low central vowel, is a type of vowel sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɐ⟩, a rotated lowercase double-barrelled letter a.
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 and back, it is normally written ⟨a⟩. If precision is required, it can be specified by using diacritics, typically centralized ⟨ä⟩.
The International Phonetic Alphabet was created soon after the International Phonetic Association was established in the late 19th century. It was intended as an international system of phonetic transcription for oral languages, originally for pedagogical purposes. The Association was established in Paris in 1886 by French and British language teachers led by Paul Passy. The prototype of the alphabet appeared in Phonetic Teachers' Association (1888b). The Association based their alphabet upon the Romic alphabet of Henry Sweet, which in turn was based on the Phonotypic Alphabet of Isaac Pitman and the Palæotype of Alexander John Ellis.
The International Phonetic Alphabet (IPA) possesses 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. Several symbols indicating secondary articulation have been dropped altogether, with the idea that they should be indicated with diacritics: for is one. In addition, the rare voiceless implosive series has been dropped.
The near-close near-back rounded vowel, or near-high near-back rounded vowel, is a type of vowel sound, used in some spoken languages. The IPA symbol that represents this sound is ⟨ʊ⟩. It is informally called "horseshoe u". Prior to 1989, there was an alternative IPA symbol for this sound, ⟨ɷ⟩, called "closed omega"; use of this symbol is no longer sanctioned by the IPA. In Americanist phonetic notation, the symbol ⟨ᴜ⟩ is used. Sometimes, especially in broad transcription, this vowel is transcribed with a simpler symbol ⟨u⟩, which technically represents the close back rounded vowel.
The mid front unrounded vowel is a type of vowel sound that is used in some spoken languages. There is no dedicated symbol in the International Phonetic Alphabet that represents the exact mid front unrounded vowel between close-mid and open-mid, but it is normally written ⟨e⟩. If precision is required, diacritics may be used, such as ⟨e̞⟩ or ⟨ɛ̝⟩. In Sinology and Koreanology, ⟨ᴇ⟩ is sometimes used, for example in the Zhengzhang Shangfang reconstructions.
The mid back rounded vowel is a type of vowel sound, used in some spoken languages. While there is no dedicated symbol in the International Phonetic Alphabet that represents the exact mid back rounded vowel between close-mid and open-mid, it is normally written ⟨o⟩. If precision is desired, diacritics may be used, such as ⟨o̞⟩ or ⟨ɔ̝⟩, the former being more common. There was an alternative IPA symbol for this sound, ⟨ꭥ⟩. A non-IPA letter ⟨ⱺ⟩ is also found.
