Quick Summary

Contour-tone languages are a type of tone language where pitch changes within a syllable are used to distinguish word meanings or grammatical categories. Unlike register-tone languages, which use steady pitches, contour-tone languages incorporate rising, falling, or more complex pitch movements. For example, a word's meaning in a contour-tone language can change based on whether its pitch rises, falls, or follows a combination of these movements. This is common in many Southeast Asian languages.1
