Obstruent in the context of "Syllabic consonant"

In linguistics, voicelessness is the property of sounds being pronounced without the larynx vibrating. Phonologically, it is a type of phonation, which contrasts with other states of the larynx, but some object that the word phonation implies voicing and that voicelessness is the lack of phonation.

The International Phonetic Alphabet (IPA) has distinct letters for many voiceless and modally voiced pairs of consonants (the obstruents), such as [p b], [t d], [k ɡ], [q ɢ], [c ɟ], [f v], and [s z]. Also, there are diacritics for voicelessness, U+0325 ◌̥ COMBINING RING BELOW and U+030A ◌̊ COMBINING RING ABOVE, which is used for letters with a descender. Diacritics are typically used with letters for prototypically voiced sounds, such as vowels and sonorant consonants: [ḁ], [l̥], [ŋ̊].In Russian use of the IPA, the voicing diacritic may be turned for voicelessness, e.g. ⟨ṋ⟩.

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 (British spelling) or tsk! tsk! (American spelling) used to express disapproval or pity (IPA [ǀ]), the tchick! used to spur on a horse (IPA [ǁ]), and the clip-clop! sound children make with their tongue to imitate a horse trotting (IPA [ǃ]). 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.

Anatomically, clicks are obstruents articulated with two closures (points of contact) in the mouth, one forward and one at the back. The enclosed pocket of air is rarefied by a sucking action of the tongue (in technical terminology, clicks have a lingual ingressive airstream mechanism). The forward closure is then released, producing what may be the loudest consonants in the language, although in some languages such as Hadza and Sandawe, clicks can be more subtle and may even be mistaken for ejectives.

Scholars have attempted to reconstruct the phonology of Old Chinese from documentary evidence. Although the writing system does not describe sounds directly, shared phonetic components of the most ancient Chinese characters are believed to link words that were pronounced similarly at that time. The oldest surviving Chinese verse, in the Classic of Poetry (Shijing), shows which words rhymed in that period. Scholars have compared these bodies of contemporary evidence with the much later Middle Chinese reading pronunciations listed in the Qieyun rhyme dictionary published in 601 AD, though this falls short of a phonemic analysis. Supplementary evidence has been drawn from cognates in other Sino-Tibetan languages and in Min Chinese, which split off before the Middle Chinese period, Chinese transcriptions of foreign names, and early borrowings from and by neighbouring languages such as Hmong–Mien, Kra-Dai, Vietic and Tocharian languages.

Although many details are disputed, most recent reconstructions agree on the basic structure. It is generally agreed that Old Chinese differed from Middle Chinese in lacking retroflex and palatal obstruents but having initial consonant clusters of some sort, and in having voiceless sonorants. Most recent reconstructions also posit consonant clusters at the end of the syllable, developing into tone distinctions in Middle Chinese.

Xiang or Hsiang (Chinese: 湘; Changsha Xiang: [sian˧ y˦˩], Mandarin: [ɕi̯aŋ˥ y˨˩˦]), also known as Hunanese, is a group of linguistically similar and historically related Sinitic languages, spoken mainly in Hunan province but also in northern Guangxi and parts of neighboring Guizhou, Guangdong, Sichuan, Jiangxi and Hubei provinces. Scholars divided Xiang into five subgroups: Lou–Shao (Old Xiang), Chang–Yi (New Xiang), Chen–Xu or Ji–Xu, Hengzhou, and Yong–Quan. Among those, Lou–Shao, or Old Xiang, still exhibits the three-way distinction of Middle Chinese obstruents, preserving the voiced stops, fricatives, and affricates. Xiang has also been heavily influenced by Mandarin, which adjoins three of the four sides of the Xiang-speaking territory, and Gan in Jiangxi Province, from where a large population immigrated to Hunan during the Ming dynasty.

Xiang-speaking Hunanese people have played an important role in Modern Chinese history, especially in those reformatory and revolutionary movements such as the Self-Strengthening Movement, Hundred Days' Reform, Xinhai Revolution and Chinese Communist Revolution. Some examples of Xiang speakers are Mao Zedong, Zuo Zongtang, Huang Xing and Ma Ying-jeou.

Modal voice is the vocal register used most frequently in speech and singing in most languages. It is also the term used in linguistics for the most common phonation of vowels. The term "modal" refers to the resonant mode of vocal folds; that is, the optimal combination of airflow and glottal tension that yields maximum vibration.

In linguistics, modal voice is the only phonation found in the vowels and other sonorants (consonants such as m, n, l, and r) of most of the languages of the world, but a significant minority contrasts modal voice with other phonations. Among obstruents (consonants such as k, g, t͡ʃ/ch, d͡ʒ/j, s, and z), it is very common for languages to contrast modal voice with voicelessness, but in English, many supposedly-voiced obstruents do not usually have modal voice.

Osage (/oʊˈseɪdʒ, ˈoʊseɪdʒ/; Osage: 𐓏𐒰𐓓𐒰𐓓𐒷 𐒻𐒷‎ Wažáže ie) is a Siouan language spoken by the people of the Osage Nation in northern Oklahoma. Their original territory was in the present-day Ohio River Valley, which they shared with other Siouan language nations. Slowly they migrated to present-day Missouri and Kansas areas (see Dhegihan migration), but they were gradually pushed west by pressure from invading colonial forces and settlement by other displaced Native American nations.

Osage has an inventory of sounds very similar to that of Dakota, also a Siouan language, plus vowel length, preaspirated obstruents and an interdental fricative (like "th" in English "then"). In contrast to Dakota, phonemically aspirated obstruents appear phonetically as affricates, and the high back vowel *u has been fronted to [y].
