Khác biệt giữa bản sửa đổi của “Thanh điệu”

Languages with simple tone systems or [[pitch accent]] may have one or two syllables specified for tone, with the rest of the word taking a default tone. Such languages differ in which tone is marked and which is the default. In [[Navajo language|Navajo]], for example, syllables have a low tone by default, while marked syllables have high tone. In the related language [[Sekani language|Sekani]], however, the default is high tone, and marked syllables have low tone.<ref>{{citechú thích web|url=http://people.umass.edu/jkingstn/web%20page/research/athabaskan%20tonogenesis%20camera%20ready%20final%2021%20october%2004.pdf|title=The Phonetics of Athabaskan Tonogenesis|last=Kingston|first=John|year=2004|work=Athabaskan Prosody|publisher=John Benjamins Press|pages=131–179|accessdate=2008-11-14}}</ref> There are parallels with stress: English stressed syllables have a higher pitch than unstressed syllables, whereas in [[Russian language|Russian]], stressed syllables have a lower pitch.
