In linguistics , speech synthesis , and music , the pitch contour of a sound is a function or curve that tracks the perceived pitch of the sound over time. Pitch contour may include multiple sounds utilizing many pitches, and can relate the frequency function at one point in time to the frequency function at a later point.
31-534: Toora-Khem (Russian: Тоора-Хем ; Tuvan : Доора-Хем , romanized: Doora-Xem ) is a rural locality (a selo ) and the administrative center of Todzhinsky District of Tuva , Russia. Population: 2,387 ( 2010 Census ) ; 2,233 ( 2002 Census ) ; 1,851 ( 1989 Soviet census ) . Due to high elevation, Toora-Khem has a subarctic climate ( Köppen climate classification Dwc ) with bitterly cold, long winters and mild, damp summers. Tuvan language Tuvan , sometimes spelt Tyvan ,
62-419: A duration that is at least (and often more than) twice as long as that of short vowels. Contrastive low pitch may occur on short vowels, and when it does, it causes them to increase in duration by at least a half. When using low pitch, Tuvan speakers employ a pitch that is at the very low end of their modal voice pitch. For some speakers, it is even lower and using what is phonetically known as creaky voice . When
93-436: A fixed reference point in the frequency function of a complex sound, and then observing the movement of this reference point as the function translates, one can generate a meaningful pitch contour consistent with human experience. For example, the vowel [e] has two primary formants , one peaking between 280 and 530 Hz and one between 1760 and 3500 Hz. When a person speaks a sentence involving multiple [e] sounds,
124-536: A high vowel [y] [u] and be preceded by a rounded vowel). See Harrison (2001) for a detailed description of Tuvan vowel harmony systems. Tuvan builds morphologically complex words by adding suffixes. For example, теве teve is 'camel', тевелер teveler is 'camels', тевелерим tevelerim is 'my camels', тевелеримден tevelerimden is 'from my camels'. Tuvan marks nouns with six cases : genitive, accusative, dative, ablative, locative, and allative. The suffixes below are in front vowels, however, except -Je
155-473: A part of the local Oirat Mongol community that is counted under the general PRC official ethnic label of "Mongol". Oirat and Tuvan children attend schools in which they use Chakhar Mongolian and Mandarin Standard Chinese , native languages of neither group. Pitch contour It is fundamental to the linguistic concept of tone , where the pitch or change in pitch of a speech unit over time affects
186-511: A stereotype of speech synthesis in popular culture. In music , the pitch contour focuses on the relative change in pitch over time of a primary sequence of played notes. The same contour can be transposed without losing its essential relative qualities, such as sudden changes in pitch or a pitch that rises or falls over time. Often used in the analysis of post-tonal music, Michael Friedmann's methodology for analyzing pitch contour assigns numeric values to notate where each pitch falls in relation to
217-524: A vowel in a monosyllabic word has low pitch, speakers apply low pitch only to the first half of that vowel (e.g. [àt] 'horse'). That is followed by a noticeable pitch rise, as the speaker returns to modal pitch in the second half of the vowel. The acoustic impression is similar to that of a rising tone like the rising pitch contour of the Mandarin second tone, but the Tuvan pitch begins much lower. However, Tuvan
248-415: A word to be either back or front. Rounding harmony, or what is sometimes called 'labial' harmony, requires a vowel to be rounded if it is a high vowel and appears in a syllable immediately following a rounded vowel. Low rounded vowels [ø] [o] are restricted to the first syllable of a word, and a vowel in a non-initial syllable may be rounded only if it meets the conditions of rounding harmony (it must both be
279-561: Is a Turkic language spoken in the Republic of Tuva in South Central Siberia , Russia . There are small groups of Tuvans that speak distinct dialects of Tuvan in China and Mongolia . While this history focuses on mostly the people of Tuva, many linguists argue that language is inevitably intertwined with the socio-historical situation of a language itself. The earliest record of Tuvan
310-465: Is a modified version of the Russian alphabet , with three additional letters: Ңң (Latin "ng" or International Phonetic Alphabet [ŋ] ), Өө (Latin "ö", [ø] ), Үү (Latin "ü", IPA [y] ). The sequence of the alphabet follows Russian, but with Ң located after Russian Н, Ө after О, and Ү after У. The letters Е and Э are used in a special way. Э is used for the short /e/ sound at the beginning of words while Е
341-526: Is characteristic of the classical Mongolian script. Moreover, the pronunciation of several letters underwent significant alteration. A few books and newspapers, including primers intended to teach adults to read, were printed using this writing system. Lopsang-Chinmit was later executed in Stalinist purges on 31 December 1941. In the USSR, Aleksandr Palmbach, Yevgeny Polivanov , and Nicholas Poppe were engaged in

#1733085175244372-441: Is considered a pitch accent language with contrastive low pitch instead of a tonal language . When the low pitch vowel occurs in a multisyllabic word, there is no rising pitch contour or lengthening effect: [àdɯ] 'his/her/its horse'. Such low pitch vowels were previously referred to in the literature as either kargyraa or pharyngealized vowels. Phonetic studies have demonstrated that the defining characteristic of such vowels
403-456: Is from the early 19th century by Wūlǐyǎsūtái zhìlüè ( Chinese : 烏里雅蘇台志略 ), Julius Klaproth 1823, Matthias Castrén 1857, Nikolay Katanov , Vasily Radlov , etc. The name Tuva goes back as early as the publication of The Secret History of the Mongols . The Tuva (as they refer to themselves) have historically been referred to as Soyons, Soyots or Uriankhais. Tuvan (also spelled Tyvan)
434-665: Is linguistically classified as a Sayan Turkic language. Its closest relative is the moribund Tofa . Although Tuvan has more speakers than endangered languages such as Seri in Mexico (est. 1000 speakers) or Nǁng in South Africa (fewer than 10 speakers), still Tuvan is endangered by global dialects around them like Russian or Mandarin . Tuvan, as spoken in Tuva, is principally divided into four dialect groups; Western, Central, Northeastern, Southeastern. Other dialects include those spoken by
465-469: Is low pitch. See Harrison 2001 for a phonetic and acoustic study of Tuvan low pitch vowels. In her PhD thesis, "Long Vowels in Mongolic Loanwords in Tuvan", Baiarma Khabtagaeva states that the history of long vowels is ambiguous. While the long vowels may originate from Mongolic languages, they could also be of Tuvan origin. In most Mongolic languages, the quality of the long vowel changes depending on
496-631: Is the Jungar Tuvan language, originating in the Altai Mountains in the western region of Mongolia. There is no accurate number of Jungar-Tuvan speakers because most currently reside in China, and the Chinese include Tuvan speakers as Mongolians in their census. Tuvan has 19 native consonant phonemes : Vowels in Tuvan exist in three varieties: long, short, and short with low pitch . Tuvan long vowels have
527-422: Is used for the same sound in the middle and at the end of words. Е is used at the beginning of words, mostly of Russian origin, to reflect the standard Russian pronunciation of that letter, /je/ . Additionally, ЭЭ is used in the middle and at the end of words for the long /e/ sound. The letter ъ is used to indicate pitch accent, as in эът èt 'meat'. In the past, approximately from 17th and 18th centuries till
558-567: The Dzungar , the Tsengel and the Dukha Tuvans, but currently these uncommon dialects are not comprehensively documented. Different dialects of the language exist across the geographic region in which Tuvan is spoken. K. David Harrison , who completed his dissertation on the Tuvan language in 2001, argues that the divergence of these dialects relates to the nomadic nature of the Tuvan nation. One subset
589-488: The 30s of the 20th century Tuvans used the traditional Mongolian script as their written language. By the late 1920s less than 1.5% of the total Tuvan population was literate in the traditional Mongolian script . Mongolian literacy was mainly possessed by the feudal nobility and officials. The absolute majority of Tuvans (with the exception of residents of some areas of the south-eastern part of Tuva, where Tuvan-Mongolian bilingualism has been preserved to this day) did not know
620-706: The ALA-LC Romanization tables for non-Slavic languages in Cyrillic script. Linguistic descriptions often employ the IPA or Turcological standards for transliteration. Tuvans in China , who live mostly in Xinjiang Autonomous Region , are included under the Mongol nationality . Some Tuvans reportedly live at Kanas Lake in the northwestern part of Xinjiang, where they are not officially recognized, and are counted as
651-597: The Mongolian language, and had long spoken only their native language. In 1926, the government of the Tuvan People's Republic asked Soviet scientists to develop a native Tuvan script. The first draft of a Tuvan alphabet based on Cyrillic was compiled by Roman Buzykaev (1875-1939) and B. Bryukhanov (Sotpa) in 1927. This alphabet contained the letters Аа, Бб, Вв, Гг, Дд, Ёё, Жж, Ӝӝ, Зз, Ии, Йй, Кк, Лл, Мм, Нн, Ҥҥ, Оо, Ӧӧ, Пп, Рр, Сс, Тт, Уу, Ӱӱ, Хх, Чч, Шш, Ыы. The first Tuvan primer

#1733085175244682-497: The Mongolic preserved the conjunction, the VCV conjunction was preserved but the long vowel still developed when it entered the Tuvan language, or the stress is on the last syllable and a long vowel in the loanword replaced a short vowel in the original word. The late layer includes loanwords in which the long vowel does not change when the word entered Tuvan. Vowels may also be nasalized in
713-530: The development of the Tuvan Latinized alphabet. These researchers utilized the so-called New Turkic Alphabet as a foundation for their work. New Turkic Alphabet was designed with the intention of facilitating unification of writing systems among all Turkic peoples. In early 1930, the Tuvan alphabet was finalized and officially introduced on June 28, 1930, by a decree of the TPR government. The approved Tuvan alphabet
744-407: The environment of nasal consonants, but nasalization is non-contrastive. Most Tuvan vowels in word-initial syllables have a low pitch and do not contrast significantly with short and long vowels. Tuvan has two systems of vowel harmony that strictly govern the distribution of vowels within words and suffixes. Backness harmony, or what is sometimes called 'palatal' harmony, requires all vowels within
775-629: The hay." Tuvan vocabulary is mostly Turkic in origin but marked by a large number of Mongolian loanwords . The language has also borrowed several Mongolian suffixes. In addition, there exist Ketic and Samoyedic substrata. A Tuvan talking dictionary is produced by the Living Tongues Institute . In contrast with most Turkic languages, which have many Arabic and Persian loanwords that even cover some basic concepts, these loanwords are very few, if any, in Tuvan, as Tuvans never adopted Islam like most Turkic peoples. The current Tuvan alphabet
806-464: The others within a musical line; the lowest pitch is assigned "0" and the highest pitch is assigned the value of n-1, in which n= the number of pitches within the segmentation. Therefore, a contour that follows the sequence of low, middle, high, would be labeled as contour classes 0, 1, and 2. Pure tones have a clear pitch, but complex sounds such as speech and music typically have intense peaks at many different frequencies. Nevertheless, by establishing
837-404: The quality of the second vowel in the conjunction. The only exception to this rule is if the conjunction is labial. The ancient Tuvan languages, in contrast, depended upon the first vowel rather than the second to determine the long vowels. Khabtagaeva divided the transformation of these loanwords into two periods: the early layer and the late layer. The words in the early layer are words in which
868-403: The semantic meaning of a sound. It also indicates intonation in pitch accent languages. One of the primary challenges in speech synthesis technology, particularly for non-tonal languages, is to create a natural-sounding pitch contour for the utterance as a whole. Unnatural pitch contours result in synthesis that sounds "lifeless" or "emotionless" to human listeners, a feature that has become
899-488: The suffixes follow vowel harmony rules. Each case suffix has a rich variety of uses and meanings, of which only the most basic ones are shown here. Verbs in Tuvan take a number of endings to mark tense , mood , and aspect . Auxiliary verbs are also used to modify the verb. For a detailed scholarly study of auxiliary verbs in Tuvan and related languages, see Anderson 2004. Tuvan employs SOV word order. For example, теве сиген чипкен (camel hay eat-PAST) "The camel ate
930-413: Was as follows: The letter Ɉ ɉ was excluded from the alphabet in 1931. By September 1943, this Latin-based alphabet was replaced by a Cyrillic-based one, which is still in use to the present day. In the post-Soviet era, Tuvan and other scholars have taken a renewed interest in the history of Tuvan letters. For bibliographic purposes, transliteration of Tuvan generally follows the guidelines described in
961-470: Was published using this alphabet, but this project was not developed further. The Latin-based alphabet for Tuvan was devised in 1930 by a Tuvan Buddhist monk, Mongush Lopsang-Chinmit (a.k.a. Lubsan Zhigmed). This project was proposed based on the German alphabet, albeit with a modified letter order. In this proposed system, all vowels were placed first (10 letters), followed by consonants (18 letters). This order
