Pitch reset

In speech, phonetic pitch reset occurs at the boundaries (pausa) between prosodic units. Over the course of such units, the median pitch of the voice declines from its initial value, sometimes reaching the lower end of the speaker's vocal range. Then, it must reset to a higher level if the person is to continue speaking. In non-tonal languages, the sudden increase in pitch is one of the principal auditory cues to the start of a new prosodic unit.

Upstep

In linguistics, upstep is a phonemic or phonetic upward shift of tone between the syllables or words of a tonal language. It is best known in the tonal languages of Sub-Saharan Africa. Upstep is a much rarer phenomenon than its counterpart, downstep. The symbol for upstep in the International Phonetic Alphabet is a superscript upward arrow [ꜛ] ([↑]). However, it is common, especially in the early research, to find a superscript (or sometimes subscript) inverted exclamation mark [ꜞ] ([¡]) or [¡], because of typographical constraints.

Downdrift

In phonetics, downdrift (also known as automatic downstep) is the cumulative lowering of pitch in the course of a sentence due to interactions among tones in a tonal language. Downdrift often occurs when the tones in successive syllables are H L H (high, low, high) or H L L H (high, low, low, high). In this case the second high tone tends to be lower than the first. The effect can accumulate so that with each low tone, the pitch of the high tones becomes slightly lower, until the end of the intonational phrase, when the pitch is "reset".

Tone (linguistics)

Tone is the use of pitch in language to distinguish lexical or grammatical meaning—that is, to distinguish or to inflect words. 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. 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.
