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.
Phonetics is a branch of linguistics that studies how humans produce and perceive sounds, or in the case of sign languages, the equivalent aspects of sign. Linguists who specialize in studying the physical properties of speech are phoneticians. The field of phonetics is traditionally divided into three sub-disciplines based on the research questions involved such as how humans plan and execute movements to produce speech, how various movements affect the properties of the resulting sound, or how humans convert sound waves to linguistic information. Traditionally, the minimal linguistic unit of phonetics is the phone—a speech sound in a language which differs from the phonological unit of phoneme; the phoneme is an abstract categorization of phones, and it is also defined as the smallest unit that discerns meaning between sounds in any given language.
The term phonation has slightly different meanings depending on the subfield of phonetics. Among some phoneticians, phonation is the process by which the vocal folds produce certain sounds through quasi-periodic vibration. This is the definition used among those who study laryngeal anatomy and physiology and speech production in general. Phoneticians in other subfields, such as linguistic phonetics, call this process voicing, and use the term phonation to refer to any oscillatory state of any part of the larynx that modifies the airstream, of which voicing is just one example. Voiceless and supra-glottal phonations are included under this definition.
The human voice consists of sound made by a human being using the vocal tract, including talking, singing, laughing, crying, screaming, shouting, humming or yelling. The human voice frequency is specifically a part of human sound production in which the vocal folds are the primary sound source.
Tone is the use of pitch in language to distinguish lexical or grammatical meaning—that is, to distinguish or to inflect words. All oral languages use pitch to express emotional and other para-linguistic information and to convey emphasis, contrast and other such features in what is called intonation, but not all languages use tones to distinguish words or their inflections, analogously to consonants and vowels. Languages that have this feature are called tonal languages; the distinctive tone patterns of such a language are sometimes called tonemes, by analogy with phoneme. Tonal languages are common in East and Southeast Asia, Africa, the Americas and the Pacific.
The glottal stop or glottal plosive is a type of consonantal sound used in many spoken languages, produced by obstructing airflow in the vocal tract or, more precisely, the glottis. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ʔ⟩.
The voiced glottal fricative, sometimes called breathy-voiced glottal transition, is a type of sound used in some spoken languages which patterns like a fricative or approximant consonant phonologically, but often lacks the usual phonetic characteristics of a consonant. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɦ⟩, and the equivalent X-SAMPA symbol is h\.
Implosive consonants are a group of stop consonants with a mixed glottalic ingressive and pulmonic egressive airstream mechanism. That is, the airstream is controlled by moving the glottis downward in addition to expelling air from the lungs. Therefore, unlike the purely glottalic ejective consonants, implosives can be modified by phonation. Contrastive implosives are found in approximately 13% of the world's languages.
Glottalization is the complete or partial closure of the glottis during the articulation of another sound. Glottalization of vowels and other sonorants is most often realized as creaky voice. Glottalization of obstruent consonants usually involves complete closure of the glottis; another way to describe this phenomenon is to say that a glottal stop is made simultaneously with another consonant. In certain cases, the glottal stop can even wholly replace the voiceless consonant. The term 'glottalized' is also used for ejective and implosive consonants; see glottalic consonant for examples.
Stød is a suprasegmental unit of Danish phonology, which in its most common form is a kind of creaky voice (laryngealization), but it may also be realized as a glottal stop, especially in emphatic pronunciation. Some dialects of Southern Danish realize stød in a way that is more similar to the tonal word accents of Norwegian and Swedish. In much of Zealand it is regularly realized as reminiscent of a glottal stop. A probably unrelated glottal stop, with quite different distribution rules, occurs in Western Jutland and is known as the vestjysk stød. The word stød itself does not have a stød.
Mongsen Ao is a member of the Ao languages, a branch of the Sino-Tibetan languages, predominantly spoken in central Mokokchung district of Nagaland, northeast India. Its speakers see the language as one of two varieties of a greater "Ao language," along with the prestige variety Chungli Ao.
Harsh voice, also called ventricular voice or pressed voice, is the production of speech sounds with a constricted laryngeal cavity, which generally involves epiglottal co-articulation. Harsh voice includes the use of the ventricular folds to damp the glottis in a way similar to what happens when a person talks while lifting a heavy load, or, if the sound is voiceless, like clearing one's throat. It contrasts with faucalized voice, which involves the expansion of the larynx.
In phonology, a register, or pitch register, is a prosodic feature of syllables in certain languages in which tone, vowel phonation, glottalization or similar features depend upon one another.
The vocal fry register is the lowest vocal register and is produced through a loose glottal closure that permits air to bubble through slowly with a popping or rattling sound of a very low frequency. During this phonation, the arytenoid cartilages in the larynx are drawn together, which causes the vocal folds to compress rather tightly and become relatively slack and compact. This process forms a large and irregularly vibrating mass within the vocal folds that produces the characteristic low popping or rattling sound when air passes through the glottal closure. The register can extend far below the modal voice register, in some cases up to 8 octaves lower, such as in the case of Tim Storms who holds the world record for lowest frequency note ever produced by a human, a G−7, which is only 0.189 Hz, inaudible to the human ear.
The most thorough treatment of the Kiowa sound system is by Laurel Watkins in a generative framework. A consideration of prosodic phenomena with acoustic analysis is in Sivertsen (1956). Earlier discussions of phonemics are Trager (1960), Merrifield (1959), Wonderly et al. (1954), and Harrington (1928).
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.
The nasal palatal approximant is a type of consonantal sound used in some oral languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨j̃⟩, that is, a j with a tilde. The equivalent X-SAMPA symbol is j~, and in the Americanist phonetic notation it is ⟨ỹ⟩.
The phonology of Danish is similar to that of the other closely related Scandinavian languages, Swedish and Norwegian, but it also has distinct features setting it apart. For example, Danish has a suprasegmental feature known as stød which is a kind of laryngeal phonation that is used phonemically. It also exhibits extensive lenition of plosives, which is noticeably more common than in the neighboring languages. Because of these and a few other features, spoken Danish can be challenging for Norwegians and Swedes to understand without training, although they can easily read written Danish.
A voiceless velar implosive is a very rare consonantal sound. The symbol for this sound in the International Phonetic Alphabet is ⟨ɠ̊⟩ or ⟨kʼ↓⟩. A dedicated IPA letter, ⟨ƙ⟩, was withdrawn in 1993.
The creaky-voiced glottal approximant is a consonant sound in some languages. In the IPA, it is transcribed as ⟨ʔ̞⟩, ⟨ʔ̰⟩, or ⟨ʔ̬⟩. It involves tension in the glottis and diminution of airflow, compared to surrounding vowels, but not full occlusion.
