In phonology, an allophone is one of multiple possible spoken sounds – or phones – used to pronounce a single phoneme in a particular language. For example, in English, the voiceless plosive and the aspirated form are allophones for the phoneme, while these two are considered to be different phonemes in some languages such as Central Thai. Similarly, in Spanish, and are allophones for the phoneme, while these two are considered to be different phonemes in English.
Approximants are speech sounds that involve the articulators approaching each other but not narrowly enough nor with enough articulatory precision to create turbulent airflow. Therefore, approximants fall between fricatives, which do produce a turbulent airstream, and vowels, which produce no turbulence. This class is composed of sounds like and semivowels like and, as well as lateral approximants like.
A fricative is a consonant produced by forcing air through a narrow channel made by placing two articulators close together. These may be the lower lip against the upper teeth, in the case of ; the back of the tongue against the soft palate in the case of German ; or the side of the tongue against the molars, in the case of Welsh. This turbulent airflow is called frication.
An affricate is a consonant that begins as a stop and releases as a fricative, generally with the same place of articulation. It is often difficult to decide if a stop and fricative form a single phoneme or a consonant pair. English has two affricate phonemes, and, often spelled ch and j, respectively.
Uvulars are consonants articulated with the back of the tongue against or near the uvula, that is, further back in the mouth than velar consonants. Uvulars may be stops, fricatives, nasals, trills, or approximants, though the IPA does not provide a separate symbol for the approximant, and the symbol for the voiced fricative is used instead. Uvular affricates can certainly be made but are rare: they occur in some southern High-German dialects, as well as in a few African and Native American languages. Uvular consonants are typically incompatible with advanced tongue root, and they often cause retraction of neighboring vowels.
The voiceless velar fricative is a type of consonantal sound used in some spoken languages. It was part of the consonant inventory of Old English and can still be found in some dialects of English, most notably in Scottish English, e.g. in loch, broch or saugh (willow).
The voiceless alveolar lateral fricative is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents voiceless dental, alveolar, and postalveolar lateral fricatives is, and the equivalent X-SAMPA symbol is K.
The voiced palatal fricative is a type of consonantal sound used in some spoken languages. The symbol in the International Phonetic Alphabet (IPA) that represents this sound is ⟨ʝ⟩, and the equivalent X-SAMPA symbol is j\. It is the non-sibilant equivalent of the voiced alveolo-palatal sibilant.
The voiced uvular fricative is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ʁ⟩, an inverted small uppercase letter ⟨ʀ⟩, or in broad transcription ⟨r⟩ if rhotic. This consonant is one of the several collectively called guttural R when found in European languages.
The voiced velar fricative is a type of consonantal sound that is used in various spoken languages. It is not found in most varieties of Modern English but existed in Old English. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɣ⟩, a Latinized variant of the Greek letter gamma, ⟨γ⟩, which has this sound in Modern Greek. It should not be confused with the graphically-similar ⟨ɤ⟩, the IPA symbol for a close-mid back unrounded vowel, which some writings use for the voiced velar fricative.
The voiceless alveolo-palatal sibilant fricative is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɕ⟩. It is the sibilant equivalent of the voiceless palatal fricative, and as such it can be transcribed in IPA with ⟨ç˖⟩.
The voiceless palatal fricative is a type of consonantal sound used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ç⟩, and the equivalent X-SAMPA symbol is C. It is the non-sibilant equivalent of the voiceless alveolo-palatal fricative.
The voiceless uvular fricative is a type of consonantal sound that is used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨χ⟩, the Greek chi. The sound is represented by ⟨x̣⟩ in Americanist phonetic notation. It is sometimes transcribed with ⟨x⟩ in broad transcription.
The voiced palatal implosive is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ ʄ ⟩, and the equivalent X-SAMPA symbol is J\_<. Typographically, the IPA symbol is a dotless lowercase letter j with a horizontal stroke that was initially created by turning the type for a lowercase letter f and a rightward hook. A very similar-looking letter, ⟨ ƒ ⟩, is used in Ewe for.
The sj-sound is a voiceless fricative phoneme found in the sound system of most dialects of Swedish. It has a variety of realisations, whose precise phonetic characterisation is a matter of debate, but which usually feature distinct labialization. The sound is represented in Swedish orthography by a number of spellings, including the digraph ⟨sj⟩ from which the common Swedish name for the sound is derived, as well as ⟨stj⟩, ⟨skj⟩, and ⟨sk⟩. The sound should not be confused with the Swedish tj-sound, often spelled ⟨tj⟩, ⟨kj⟩, or ⟨k⟩.
This article is about the sound system of the Navajo language. The phonology of Navajo is intimately connected to its morphology. For example, the entire range of contrastive consonants is found only at the beginning of word stems. In stem-final position and in prefixes, the number of contrasts is drastically reduced. Similarly, vowel contrasts found outside of the stem are significantly neutralized. For details about the morphology of Navajo, see Navajo grammar.
In the Dutch language, hard and soft G refers to a phonetic phenomenon of the pronunciation of the letters ⟨g⟩ and ⟨ch⟩ and also a major isogloss within that language.
This article discusses the phonological system of standard Russian based on the Moscow dialect. For an overview of dialects in the Russian language, see Russian dialects. Most descriptions of Russian describe it as having five vowel phonemes, though there is some dispute over whether a sixth vowel,, is separate from. Russian has 34 consonants, which can be divided into two types:
The voiceless alveolar fricatives are a type of fricative consonant pronounced with the tip or blade of the tongue against the alveolar ridge just behind the teeth. This refers to a class of sounds, not a single sound. There are at least six types with significant perceptual differences:
Manyjilyjarra is generally considered a dialect of the Western Desert language.
