In phonology, an allophone is one of multiple possible spoken sounds – or phones – or signs 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.
In phonetics, aspiration is the strong burst of breath that accompanies either the release or, in the case of preaspiration, the closure of some obstruents. In English, aspirated consonants are allophones in complementary distribution with their unaspirated counterparts, but in some other languages, notably most South Asian languages and East Asian languages, the difference is contrastive.
Breathy voice is a phonation in which the vocal folds vibrate, as they do in normal (modal) voicing, but are adjusted to let more air escape which produces a sighing-like sound. A simple breathy phonation,, can sometimes be heard as an allophone of English between vowels, such as in the word behind, for some speakers.
Click consonants, or clicks, are speech sounds that occur as consonants in many languages of Southern Africa and in three languages of East Africa. Examples familiar to English-speakers are the tut-tut or tsk! tsk! used to express disapproval or pity, the tchick! used to spur on a horse, and the clip-clop! sound children make with their tongue to imitate a horse trotting. However, these paralinguistic sounds in English are not full click consonants, as they only involve the front of the tongue, without the release of the back of the tongue that is required for clicks to combine with vowels and form syllables.
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.
In phonetics, a plosive, also known as an occlusive or simply a stop, is a pulmonic consonant in which the vocal tract is blocked so that all airflow ceases.
Voice or voicing is a term used in phonetics and phonology to characterize speech sounds. Speech sounds can be described as either voiceless or voiced.
Sandawe is a language spoken by about 60,000 Sandawe people in the Dodoma Region of Tanzania. Sandawe's use of click consonants, a rare feature shared with only two other languages of East Africa – Hadza and Dahalo, had been the basis of its classification as a member of the defunct Khoisan family of Southern Africa since Albert Drexel in the 1920s. Recent investigations however suggest that Sandawe may be related to the Khoe family regardless of the validity of Khoisan as a whole. A discussion of Sandawe's linguistic classification can be found in Sands (1998).
English phonology is the system of speech sounds used in spoken English. Like many other languages, English has wide variation in pronunciation, both historically and from dialect to dialect. In general, however, the regional dialects of English share a largely similar phonological system. Among other things, most dialects have vowel reduction in unstressed syllables and a complex set of phonological features that distinguish fortis and lenis consonants.
In linguistics, fortis and lenis, sometimes identified with 'tense' and 'lax', are pronunciations of consonants with relatively greater and lesser energy, respectively. English has fortis consonants, such as the p in pat, with a corresponding lenis consonant, such as the b in bat. Fortis and lenis consonants may be distinguished by tenseness or other characteristics, such as voicing, aspiration, glottalization, velarization, length, and length of nearby vowels. Fortis and lenis were coined for languages where the contrast between sounds such as 'p' and 'b' does not involve voicing.
In phonetics, voice onset time (VOT) is a feature of the production of stop consonants. It is defined as the length of time that passes between the release of a stop consonant and the onset of voicing, the vibration of the vocal folds, or, according to other authors, periodicity. Some authors allow negative values to mark voicing that begins during the period of articulatory closure for the consonant and continues in the release, for those unaspirated voiced stops in which there is no voicing present at the instant of articulatory closure.
In linguistics, a tenuis consonant is an obstruent that is voiceless, unaspirated and unglottalized.
The Sikkimese language, also called Sikkimese, Bhutia, or Drenjongké, Dranjoke, Denjongka, Denzongpeke and Denzongke, belongs to the Tibeto-Burman languages. It is spoken by the Bhutia in Sikkim, India and in parts of Koshi, Nepal. The Sikkimese people refer to their own language as Drendzongké and their homeland as Drendzong. Up until 1975 Sikkimese was not a written language. After gaining Indian Statehood the language was introduced as a school subject in Sikkim and the written language was developed.
Tsou is a divergent Austronesian language spoken by the Tsou people of Taiwan. Tsou is a threatened language; however, this status is uncertain. Its speakers are located in the west-central mountains southeast of the Chiayi/Alishan area in Taiwan.
Catherine Phebe Browman was an American linguist and speech scientist. She received her Ph.D. in linguistics from the University of California, Los Angeles (UCLA) in 1978. Browman was a research scientist at Bell Laboratories in New Jersey (1967–1972). While at Bell Laboratories, she was known for her work on speech synthesis using demisyllables. She later worked as researcher at Haskins Laboratories in New Haven, Connecticut (1982–1998). She was best known for developing, with Louis Goldstein, of the theory of articulatory phonology, a gesture-based approach to phonological and phonetic structure. The theoretical approach is incorporated in a computational model that generates speech from a gesturally-specified lexicon. Browman was made an honorary member of the Association for Laboratory Phonology.
The phonology of the Zuni language as spoken in the southwestern United States is described here. Phonology is a branch of linguistics that studies how languages or dialects systematically organize their sounds.
The phonology of Burmese is fairly typical of a Southeast Asian language, involving phonemic tone or register, a contrast between major and minor syllables, and strict limitations on consonant clusters.
Nasal clicks are click consonants pronounced with nasal airflow. All click types have nasal variants, and these are attested in four or five phonations: voiced, voiceless, aspirated, murmured, and—in the analysis of Miller (2011)—glottalized.
Glottalized clicks are click consonants pronounced with closure of the glottis. All click types have glottalized variants. They are very common: All of the Khoisan languages of Africa have them, as does Dahalo and the Bantu languages Yeyi and Xhosa. They are produced by making a glottal stop, which stops the flow of air, and then using the front of the tongue to make the click sound in the middle of the glottal stop.
