Intonation and Information Structure
Chapter Objectives
By the end of this chapter, you will be able to:
- Distinguish intonation from lexical tone and from lexical stress.
- Identify phrase boundaries and prominent elements in an utterance.
- Describe global rises, falls, and other common intonational contours.
- Relate intonation to discourse context without assigning fixed, universal meanings to a contour.
- Interpret a declared, introductory intonation-notation system.
- Compare phrase-level pitch patterns across named varieties.
An Observable Problem
Chapter 21 established that in a lexical-tone language, pitch can attach permanently to a word, changing its meaning no matter where the word appears in a sentence. That chapter also previewed a second, very different way that pitch does work in language: pitch that rises and falls across an entire phrase or sentence rather than sitting on a single syllable. Consider the same sentence, spoken twice with identical words in an identical order, but with the pitch pattern across the whole utterance shaped differently each time. Listeners in many languages report a different overall effect: perhaps one version sounds like a question and the other like a statement, or perhaps one sounds finished and the other sounds like the speaker has more to say.
Nothing about the words has changed. No segment has changed. If the language does not use lexical tone, then no word-level pitch category has changed either. What has changed is the shape of pitch across the phrase, and that shape is doing real communicative work: marking where one idea ends and another begins, showing what information is new or already known to the listener, or signaling how the speaker feels about what is being said.
This chapter asks three questions:
- How does phrase-level pitch patterning, called intonation, differ analytically from the lexical tone and lexical stress systems already introduced, and how can a learner tell which system is responsible for a given pitch movement?
- What recurring pitch events, such as boundaries and points of prominence, organize an intonation contour, and how can a beginner represent them using one declared notation system?
- Why is it inaccurate to assign a single, fixed meaning, such as "questioning," to a rise or a fall, and what evidence is needed before making a claim about what a specific contour communicates in a specific language or context?
Intonation Versus Tone and Stress
Purpose: place intonation precisely alongside the two systems already studied, lexical stress in Chapter 20 and lexical tone in Chapter 21, so that a pitch movement is never assigned to the wrong system by default.
Intonation is the patterning of pitch across a phrase or sentence that is not tied to the identity of an individual word. An intonation contour spans multiple syllables, often an entire utterance, and can change while every word in the utterance stays the same. Intonation is layered on top of whatever word-level pitch or stress pattern the language independently requires, rather than replacing it.
Chapter 20 introduced the diagnostic that separates lexical stress, a relatively fixed property of a word, from phrase-level prominence, which can shift depending on what the speaker wants to highlight. Chapter 21 extended a parallel diagnostic to separate lexical tone, fixed to a word regardless of sentence context, from intonation, which varies with sentence type and discourse function. This chapter uses the same underlying test: if a pitch or prominence pattern is stable across contexts for a specific word, it belongs to that word's stress or tone; if it shifts with the sentence's function, structure, or the speaker's communicative goal, it belongs to intonation.
Lexical stress, lexical tone, and intonation are three different systems, but they share a family of diagnostics: ask whether the pattern is a fixed property of a specific word or a variable property of the phrase or sentence containing that word. A fixed pattern points to stress or tone; a variable pattern that depends on sentence type, focus, or discourse context points to intonation. Applying this diagnostic carefully prevents a learner from mistaking an intonational rise for a tone or mistaking sentence stress for a lexical accent.
As Chapter 21 noted, a language can have lexical tone and intonation at the same time, with the two systems layered together rather than one displacing the other. The same is true of stress and intonation: a language with lexical stress still uses intonation to mark phrase boundaries, prominence at the sentence level, and discourse meaning. Separating the contribution of each system to a given pitch trace is an analytical skill, not something that can be read directly off a single recording without training.
Phrase Boundaries and Prominent Elements
Purpose: introduce the two structural building blocks of an intonation contour, phrase boundaries and points of prominence, before assigning any meaning to a specific pitch shape.
An intonation contour is organized around two recurring structural elements:
- Phrase boundaries mark the edges of intonational units, the stretches of speech over which a single coherent pitch pattern extends. A boundary is often, though not always, accompanied by a pause, a lengthening of the final syllable before the boundary, and a noticeable pitch movement at the edge.
- Prominent elements are the syllables within a phrase that receive the greatest perceptual emphasis, frequently realized through a combination of pitch movement, increased duration, and increased intensity, extending the cues introduced for lexical stress in Chapter 20 to the phrase level.
A useful first step in analyzing any intonation contour is to locate its boundaries before attempting to describe its pitch shape in detail. Segmenting a long utterance into intonational phrases, and then identifying the most prominent syllable within each phrase, gives the analysis a structure to build on rather than treating the pitch trace as one undifferentiated curve.
Beginners sometimes assume that the most prominent element in a phrase is always its final word. This is a common pattern in some languages under neutral, non-contrastive conditions, but it is not a universal rule. A speaker can shift prominence to an earlier word to highlight new information, to correct a previous statement, or to draw a contrast, a phenomenon developed further later in this chapter under information structure. Locate prominence by listening for the cues themselves rather than by assuming its position in advance.
Global Rises, Falls, and Common Contours
Purpose: describe recurring, broadly attested contour shapes as a starting vocabulary for analysis, without implying that every language organizes its contours identically.
Across many, though not all, studied languages, a small set of global contour shapes recur often enough to serve as a useful descriptive starting point:
- A global fall, in which pitch descends across the phrase or drops sharply near the end, frequently associated in many languages with a sense of completion or finality.
- A global rise, in which pitch ascends across the phrase or rises sharply near the end, frequently associated in many languages with incompleteness, continuation, or certain question types.
- A rise-fall or fall-rise, in which the phrase combines both movements, often associated with more complex meanings such as contrast, reservation, or implication.
- A relatively level or plateau contour, in which pitch changes comparatively little across the phrase, which some languages and registers use for lists, routine information, or a deliberately flat affect.
Illustrative shapes and frequently reported associations, not fixed rules; the same shape can carry different functions across languages, registers, and speakers.
Error: Learning the four shapes above as a fixed universal code, so that "rise equals question" is applied automatically to any language or utterance.
Correction: Treat these shapes as a starting descriptive vocabulary, confirmed for a given language and context only with evidence. The information-structure section below develops this caution further.
Notating Intonation
Purpose: introduce the course's declared, limited intonation-notation system, connected to the boundary and prominence concepts above and kept distinct from the tone notation of Chapter 21.
This textbook uses a limited, explicitly defined set of marks for introductory intonation notation, sufficient for the analysis expected at this stage without adopting a complete autosegmental or ToBI-style system, which lies beyond this book's scope.
| Symbol | Name | Meaning |
|---|---|---|
| | | Minor group mark | A minor intonational boundary, typically with a smaller pitch movement and little or no pause. |
| ‖ | Major group mark | A major intonational boundary, typically with a more substantial pitch movement, frequently with a pause. |
| ‿ | Linking mark | Indicates the absence of an expected break between two words or syllables, connecting to the linking processes developed further in Chapter 23. |
| ↗ | Global rise | Marks a rising pitch movement across the marked stretch of speech. |
| ↘ | Global fall | Marks a falling pitch movement across the marked stretch of speech. |
Combine the boundary marks with the primary and secondary stress marks reviewed from Chapter 20 to indicate where the most prominent syllable of a phrase falls, and use the global rise and fall marks at the point in the phrase where the movement occurs, typically near a boundary. As in Chapter 21, do not mix this system with an unrelated notation, such as informal arrows or punctuation invented for a single exercise, without declaring the substitution explicitly.
Error: Using ordinary punctuation, such as a question mark or exclamation point, as if it were a phonetic transcription of intonation.
Correction: Punctuation reflects orthographic and grammatical convention, not measured pitch behavior, and different languages punctuate differently. Use the declared boundary and contour marks introduced in this chapter, or a fuller system in advanced work, to represent intonation itself.
Intonation and Information Structure
Purpose: connect intonational prominence to discourse meaning carefully, showing how a contour interacts with what is new, given, or contrastive in a conversation, without assigning that contour one fixed universal meaning.
Information structure refers to how an utterance organizes information relative to what speaker and listener already share, distinguishing, for example, information that is new to the conversation from information that has already been established. Intonational prominence frequently interacts with information structure: a speaker may shift the most prominent syllable in a sentence away from its default position specifically to mark a word as newly introduced, contrastive, or corrective.
Because a shift in prominence can signal contrast, correction, emphasis, or new information depending on context, the same phrase-level pitch event can support several different discourse functions. Determining which function is active in a given utterance requires attention to the surrounding conversational context, not just the pitch trace in isolation.
It is tempting to state a simple rule such as "a final rise marks a question." This rule fails as a universal claim. Many languages use a final rise for a substantial share of yes-no questions, but the same or similar languages also use rises for lists, for continuation before a pause, for polite or hedged statements, and for other functions, while some question types are marked primarily by word order or a question particle rather than by pitch at all. A specific claim about what a specific contour means in a specific language requires evidence from that language, not an assumption carried over from a learner's first language.
Because English is the primary comparison language of this textbook, learners should be especially cautious about projecting English intonational habits onto other languages. English intonation itself varies by regional and social variety in ways that affect politeness, question marking, and emphasis, so even English-internal generalizations require care, consistent with the reference-variety policy applied throughout the course.
Across Languages
Some varieties of English, in some social and regional contexts, are documented as using a rising terminal contour, sometimes discussed under the label "uptalk," on utterances that are grammatically statements rather than questions. Researchers have proposed several possible discourse functions for this pattern, including checking for listener engagement or softening an assertion, and the pattern has also attracted significant social judgment that is not linguistically grounded. Treat any specific claim about this pattern's function or social distribution as requiring a specific source and variety label, not a general fact about English.
Not every language relies primarily on intonation to mark a yes-no question. Many languages instead use a dedicated question particle, a change in word order, or a combination of a particle and a more modest pitch adjustment, with intonation playing a smaller or different role than it does in some well-studied European languages. This reinforces a point made throughout this book: a familiar pattern from one language, or one family of languages, should not be assumed to generalize.
In lexical-tone languages such as Standard Mandarin, introduced in Chapter 21, intonation does not override the tone of individual syllables in the way it can shift stress placement in a stress language; instead, phrase-level pitch adjustments are superimposed on the existing tone pattern, for example by gradually raising or lowering the overall pitch register across a phrase while each syllable's tone shape remains recognizable. Untangling the two contributions in such languages requires dedicated instrumental analysis and is an active area of research rather than a settled, simple procedure.
Analysis Exercises
These exercises apply the boundary, prominence, contour, and information-structure concepts introduced in this chapter to controlled data. Justify each decision using the diagnostics described above, and avoid assigning a single fixed meaning to a contour without stated evidence.
Exercise A — Boundaries and Prominence
For each supplied sentence, mark where you would expect at least one intonational boundary using the minor or major group marks introduced in this chapter, and identify the syllable most likely to carry the greatest prominence under a neutral, non-contrastive reading.
- "When the meeting ends we will send the report."
- "She works downtown but she lives near the river."
Exercise B — Tone, Stress, or Intonation?
For each supplied scenario, state whether the described pitch or prominence pattern is best analyzed as lexical tone, lexical stress, phrase-level prominence, or intonation, and justify your answer using the diagnostics developed across Chapters 20 through 22.
- A specific syllable of a specific word is always produced with a rising pitch shape, in every sentence position and every sentence type, in a language previously established to have no lexical tone.
- A speaker shifts extra emphasis onto an earlier word in a sentence specifically to correct a listener's mistaken assumption about who performed an action.
Exercise C — Contour and Function
For the supplied contour description, propose one plausible discourse function it could serve, and explain what additional evidence would be needed to confirm that function for a specific language rather than merely propose it.
Description: a phrase-final fall-rise contour on an utterance that is grammatically a statement.
Common Mistakes
Error: Treating every pitch movement in an utterance as intonation, without checking whether the language has lexical tone or lexical stress that could account for part of the pattern.
Correction: Apply the diagnostic developed across Chapters 20 through 22 before attributing a pitch movement to intonation: confirm whether the movement is tied to a specific word regardless of context, pointing to tone or stress, or whether it varies with sentence type, structure, or discourse goal, pointing to intonation.
Error: Assuming that the final word of a sentence is always the most prominent element.
Correction: Final-word prominence is common under neutral conditions in some languages but is not universal and can shift for contrastive, corrective, or discourse-structural reasons. Identify prominence from its acoustic cues and context rather than assuming its position.
Error: Assigning a fixed universal meaning, such as "rise equals question," to a contour shape without evidence from the specific language and context.
Correction: A given contour shape can serve multiple discourse functions even within one language, and different languages assign different functions to similar shapes. State a proposed function as a hypothesis requiring evidence, not as an automatic rule.
Chapter Review
Part A — Intonation Versus Tone and Stress
1. State the diagnostic this chapter uses to separate intonation from lexical tone and lexical stress, and explain why the same diagnostic family applies to all three systems.
2. Explain how intonation can be layered on top of a language's lexical tone system without erasing the individual tones.
Part B — Boundaries, Prominence, and Contours
1. Distinguish a phrase boundary from a point of prominence, and identify at least one acoustic cue associated with each.
2. Describe the four common global contour shapes introduced in this chapter and one frequently reported association for each, noting why the association should not be treated as a fixed rule.
Part C — Information Structure and Variation
1. Explain how a shift in prominence can mark contrastive or corrective information, using the example pair from this chapter or a comparable example.
2. Explain why "a rise always marks a question" is not a defensible universal claim, citing at least two competing functions or counterexamples discussed in this chapter.
Cumulative Review
1. From Chapter 20: Compare phrase-level prominence, introduced there, with the prominence concept developed further in this chapter. What has been added to the earlier description?
2. From Chapter 21: Explain how the diagnostic separating lexical tone from intonation in Chapter 21 anticipated the fuller three-way diagnostic developed in this chapter.
3. Preview for Chapter 23: This chapter introduced the linking mark and mentioned that linking is developed further in the next chapter. Predict, based on the mark's description here, what kind of connected-speech phenomenon Chapter 23 is likely to address in more detail.
Self-Check
Before moving to Chapter 23, confirm that you can do the following without looking at your notes:
- Distinguish intonation from lexical tone and lexical stress using a shared diagnostic.
- Locate a plausible phrase boundary and a plausible point of prominence in a written sentence.
- Name and describe the four common global contour shapes introduced in this chapter.
- Use the minor group, major group, linking, rise, and fall marks without mixing them with unrelated notation.
- Explain why a specific contour's discourse function requires evidence rather than assumption.
- Explain how a shift in prominence can relate to information structure.
If any of these tasks are difficult, review the relevant section before reading Chapter 23. Chapter 23 moves from phrase-level pitch to the broader set of contextual changes, including linking, that occur across connected speech.

Analysis Exercises — Exercise A
1. A minor or major boundary is plausible after "ends," separating the subordinate time clause from the main clause; under a neutral reading, prominence most likely falls on "report," the final content word. 2. A boundary is plausible after "downtown," separating the two coordinated clauses; each clause has its own likely prominent syllable, with "downtown" prominent in the first clause and "river" prominent in the second under a neutral reading. Learners may reasonably propose slightly different boundary locations if justified.
Analysis Exercises — Exercise B
1. Lexical stress or, if the language has been independently established to lack lexical tone, most likely lexical stress with an associated pitch cue; the pattern is fixed to the word across all contexts, matching the diagnostic for a word-level rather than phrase-level system, and the scenario explicitly rules out lexical tone. 2. Intonation interacting with information structure; the prominence shift is motivated by the discourse goal of correcting a specific piece of information, matching the diagnostic for a phrase-level, context-dependent pattern rather than a fixed word-level one.
Analysis Exercises — Exercise C
A phrase-final fall-rise on a statement is often associated in some languages and varieties with reservation, implication, or an unstated contrast, such as suggesting "this is true, but something else follows." Confirming this function for a specific language would require examining multiple authentic examples in context, ideally with native-speaker judgments or corpus evidence, rather than relying on the general association alone, since the same shape can carry different functions in different languages or registers.
Chapter Review — Part A
1. The diagnostic asks whether a pitch or prominence pattern is fixed to a specific word across all contexts, pointing to stress or tone, or varies with sentence type, structure, or discourse goal, pointing to intonation; the same underlying logic applies across all three systems because each system operates at a different structural level, word versus phrase, and the diagnostic tests which level is responsible for a given pattern. 2. Intonation is superimposed on the existing tone pattern by adjusting the overall pitch register or trend across a phrase while each syllable's individually contrastive tone shape remains recognizable, so the two systems operate together rather than one canceling the other.
Chapter Review — Part B
1. A phrase boundary marks the edge of an intonational unit and is often cued by a pause, final lengthening, and a pitch movement at the edge; a point of prominence is the most perceptually emphasized syllable within a phrase and is often cued by a combination of pitch movement, duration, and intensity. 2. A global fall is often associated with completion or finality; a global rise is often associated with incompleteness, continuation, or some question types; a rise-fall or fall-rise is often associated with more complex meanings such as contrast or reservation; a level or plateau contour is often associated with lists or routine information. These associations should not be treated as fixed rules because the same shape can serve different functions across languages, registers, and speakers, as developed in the information-structure section.
Chapter Review — Part C
1. In the example pair, prominence on the final word "salad" under a neutral reading simply completes the statement, while shifting prominence to "soup" in the second version marks that word as part of an explicit contrast with the alternative the speaker is rejecting, showing how prominence placement can track what is being contrasted or corrected rather than defaulting to sentence-final position. 2. The claim fails because a final rise is documented as serving multiple functions, including marking certain question types but also marking lists, continuation, and some statement types such as those associated with rising terminals in some English varieties, and because some languages mark questions primarily through particles or word order rather than pitch, as discussed in the cross-language material.
Cumulative Review
1. Chapter 20 introduced phrase-level prominence primarily as a contrast case to lexical stress; this chapter adds structural detail, connecting prominence to phrase boundaries, contour shapes, and information structure, and showing how prominence placement itself can shift for contrastive or corrective discourse reasons. 2. Chapter 21's diagnostic, asking whether a pitch pattern is fixed to a word or varies with sentence context, is a special case of the fuller diagnostic this chapter applies across stress, tone, and intonation together, generalizing the same underlying logic to a third system. 3. Because the linking mark is described here as indicating the absence of an expected break between words, Chapter 23 is likely to address how words connect and blend together in fluent, connected speech, extending beyond the single-phrase focus of this chapter.
Looking Ahead
What You Can Now Do
You can now distinguish intonation from lexical tone and lexical stress using a shared diagnostic, identify phrase boundaries and points of prominence, describe common global contour shapes, use a declared introductory intonation notation without mixing it with unrelated marks, relate intonation to information structure without assigning fixed universal meanings to a contour, and compare phrase-level pitch patterns responsibly across named varieties. Together with Chapters 20 and 21, you now have a complete introductory picture of how prominence and pitch organize speech from the syllable to the phrase.
