  2. Intonation (linguistics) - Wikipedia

    en.wikipedia.org/wiki/Intonation_(linguistics)

    Thus, sentence patterns can be thought of as bands whose pitch varies over the course of the sentence, and changes of syllable pitch cause fluctuations within the band. Furthermore, the details of Mandarin intonation are affected by various factors like the tone of the final syllable, the presence or absence of focus (centering of attention) on ...

  3. Immediate constituent analysis - Wikipedia

    en.wikipedia.org/wiki/Immediate_constituent_analysis

    In linguistics, Immediate Constituent Analysis (ICA) is a syntactic theory which focuses on the hierarchical structure of sentences by isolating and identifying the constituents. While the idea of breaking down sentences into smaller components can be traced back to early psychological and linguistic theories, ICA as a formal method was ...

  4. Tone (linguistics) - Wikipedia

    en.wikipedia.org/wiki/Tone_(linguistics)

    Tone is the use of pitch in language to distinguish lexical or grammatical meaning—that is, to distinguish or to inflect words. [1] All oral 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 ...

  5. Pitch contour - Wikipedia

    en.wikipedia.org/wiki/Pitch_contour

    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.

  6. Deep structure and surface structure - Wikipedia

    For example, the sentences "Pat loves Chris" and "Chris is loved by Pat" mean roughly the same thing and use similar words. Some linguists, Chomsky in particular, have tried to account for this similarity by positing that these two sentences are distinct surface forms that derive from a common (or very similar [ 1 ] ) deep structure.

  7. Sentence function - Wikipedia

    en.wikipedia.org/wiki/Sentence_function

    The declarative sentence is the most common kind of sentence in language, in most situations, and in a way can be considered the default function of a sentence. What this means essentially is that when a language modifies a sentence in order to form a question or give a command, the base form will always be the declarative.

  8. Prosodic unit - Wikipedia

    en.wikipedia.org/wiki/Prosodic_unit

    At the boundaries between declination units, the pitch and tempo reset; for this reason the final one of the shorter internal contours is said to have final prosody, whereas the others are said to have continuing prosody. These two levels of the hierarchy may be schematized as follows:

  9. Speech - Wikipedia

    en.wikipedia.org/wiki/Speech

    Speech is the subject of study for linguistics, cognitive science, communication studies, psychology, computer science, speech pathology, otolaryngology, and acoustics. Speech compares with written language, [1] which may differ in its vocabulary, syntax, and phonetics from the spoken language, a situation called diglossia.
