These may be combined into a tongue-twister: A minimal set based on ma are, in pinyin transcription: These tones combine with a syllable such as ma to produce different words. A neutral tone, with no specific contour, used on weak syllables its pitch depends chiefly on the tone of the preceding syllable.A short, sharply falling tone, starting high and falling to the bottom of the speaker's vocal range: /â/ (pinyin ⟨à⟩).A low tone with a slight fall (if there is no following syllable, it may start with a dip then rise to a high pitch): /à/ (pinyin ⟨ǎ⟩).A tone starting with mid pitch and rising to a high pitch: /ǎ/ (pinyin ⟨á⟩).The corresponding tone letters are ˥ ˧˥ ˨˩˦ ˥˩. In the convention for Chinese, 1 is low and 5 is high. Vietnamese and Chinese by far have the most heavily studied tone systems as well as amongst their various dialects.īelow is a table of the six Vietnamese tones and their corresponding tone accent or diacritics: In tonal languages, each syllable has an inherent pitch contour, and thus minimal pairs (or larger minimal sets) exist between syllables with the same segmental features (consonants and vowels) but different tones. Most languages use pitch as intonation to convey prosody and pragmatics, but this does not make them tonal languages. Tonal languages are different from pitch-accent languages in that tonal languages can have each syllable with an independent tone whilst pitch-accent languages may have one syllable in a word or morpheme that is more prominent than the others. Tonal languages are common in East and Southeast Asia, Africa, the Americas and the Pacific. Languages that have this feature are called tonal languages the distinctive tone patterns of such a language are sometimes called tonemes, by analogy with phoneme. All verbal languages use pitch to express emotional and other para-linguistic information and to convey emphasis, contrast and other such features in what is called intonation, but not all languages use tones to distinguish words or their inflections, analogously to consonants and vowels. Tone is the use of pitch in language to distinguish lexical or grammatical meaning-that is, to distinguish or to inflect words.

Pitch contour may include multiple sounds utilizing many pitches, and can relate to frequency function at one point in time to the frequency function at a later point.This article contains phonetic transcriptions in the International Phonetic Alphabet (IPA). 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. When a person speaks a sentence involving multiple e sounds, the peaks will shift within these ranges, and the movement of the peaks between two instances establishes the difference in their values on the pitch contour.įreebase Rate this definition: 0.0 / 0 votes Nevertheless, by establishing 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.įor example, the vowel e has two primary formants, one peaking between 280 and 530 Hz and one between 17 Hz. Pure tones have a clear pitch, but complex sounds such as speech and music typically have intense peaks at many different frequencies. 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. In music, the pitch contour focuses on the relative change in pitch over time of a primary sequence of played notes. Unnatural pitch contours result in synthesis that sounds "lifeless" or "emotionless" to human listeners, a feature that has become a stereotype of speech synthesis in popular culture. One of the primary challenges in speech synthesis technology, particularly for Western languages, is to create a natural-sounding pitch contour for the utterance as a whole. It also indicates intonation in pitch accent languages. It is fundamental to the linguistic concept of tone, where the pitch or change in pitch of a speech unit over time affects the semantic meaning of a sound. 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.
