Capstone: A Phonetic Profile
Chapter Objectives
By the end of this chapter, you will be able to:
- Synthesize articulatory, auditory, phonological, and acoustic evidence into a single coherent profile.
- Apply IPA consistently across every component of the profile.
- Explain the limits of the selected analysis.
- Distinguish established facts from analytical decisions throughout the document.
- Present variation respectfully, without treating one form as the only correct one.
- Prioritize useful perception and production goals based on contrast and communicative consequence.
- Audit the profile for technical and editorial accuracy.
- Revise a complete profile using feedback.
An Observable Problem
You now hold every component a phonetic profile requires. Chapter 29 gave you a research plan naming a variety, a set of answerable questions, and a source ledger. Chapter 30 gave you a draft segmental inventory: consonant chart, vowel chart, major allophones, and an orthography-sound correspondence table. Chapter 31 gave you a phonotactic profile, a prosodic profile, a connected-speech section, a variation statement, representative sample transcriptions, and a ranked list of perception and production priorities.
None of these components was ever a finished product on its own. A consonant chart without a variation statement implies a single uniform pronunciation. A prosodic profile without a phonotactic profile leaves stress and tone floating free of the syllables that carry them. A priority list without a source ledger asks a reader to trust conclusions they cannot verify. The capstone is not a new research task; it is the disciplined act of assembling what you have already verified into one document that a reader can trust and use.
This chapter asks three questions:
- What must every finished phonetic profile contain, regardless of which language it describes?
- How does an analyst audit a completed profile for the same evidentiary and notational discipline required of every individual component?
- What should a responsible profile explicitly refuse to claim, and how should it say so?
Key Terms
- Phonetic profile: a complete, documented account of a language variety's sound system, combining inventory, phonotactic, prosodic, connected-speech, and variation evidence with stated priorities and limitations.
- Scope and source-method statement: the section of the profile that names the variety, states the research questions from Chapter 29, and identifies the evidence base and its limits.
- Technical self-audit: a systematic check of a finished profile's IPA accuracy, delimiter use, internal consistency, and adherence to the confirmed-absence, undocumented-gap, and disputed-cell distinctions used throughout Chapters 30 and 31.
- Revision memorandum: a short document explaining what changed between a draft profile and a revised profile, and why.
- Bounded claim: a statement whose scope matches the evidence actually available, neither overreaching beyond the sources nor hedging away all useful content.
Language and Reference-Variety Statement; Scope and Source-Method Statement
Purpose: open the capstone profile the way Chapter 29 taught you to open any research plan, so a reader knows immediately what variety is described and on what evidence.
Begin the profile with a short statement naming the language and the specific reference variety, using a precise label rather than an unqualified label such as "standard" or "regular" pronunciation, consistent with the reference-variety policy established across the course. Follow this with a scope and source-method statement that restates the research questions from your Chapter 29 proposal, names the sources in your ledger by type and priority, and states plainly what the evidence does and does not allow you to claim.
This opening section is short by design. Its purpose is orientation, not persuasion. A reader who reads only this section should already know which variety is described, roughly how much evidence supports the profile, and where the profile's boundaries lie.
Error: Naming a language without a variety label, then describing features that actually belong only to one regional or social variety among several.
Correction: State the reference variety in the opening section and repeat it wherever a claim could otherwise be mistaken for a language-wide generalization.
Orthography-Sound Overview
Purpose: carry forward the orthography-sound correspondence table from Chapter 30 as a short overview that orients a reader before the full inventory.
Summarize, in a few sentences, how closely the variety's ordinary writing system corresponds to its sound system, using the orthographic-depth concept introduced in Chapter 2. Note any systematic mismatches that matter for a learner approaching the variety for the first time, and point the reader to the full correspondence table carried over from Chapter 30 rather than repeating it in full here.
Consonant Inventory and Vowel Inventory
Purpose: incorporate the verified consonant and vowel charts from Chapter 30 as the segmental core of the profile.
Insert the consonant chart and vowel chart developed and sourced in Chapter 30, organized by airstream, phonation, place, and manner for consonants and by height, backness, and rounding for vowels, following the chart conventions established in Chapters 7, 8, 14, and 15. Preserve the confirmed-absence, undocumented-gap, and disputed-cell distinctions from Chapter 30 rather than presenting a fully filled chart if your evidence does not support one.
| Chart cell | Status | Notation practice |
|---|---|---|
| Attested phoneme | Confirmed absence or presence, source-backed | Symbol entered normally, with source noted in the accompanying key |
| No source addresses the cell | Undocumented gap | Cell left blank and marked as undocumented, not marked as absent |
| Sources disagree | Disputed cell | Both analyses noted, with the disagreement stated rather than silently resolved |
A segmental inventory alone cannot show how sounds combine into syllables, which syllables carry prominence, or how careful forms change in connected speech. Present the inventory as one component among several, not as a standalone deliverable, and connect it explicitly to the phonotactic and prosodic sections that follow.
Major Allophones
Purpose: carry forward the major-allophone list from Chapter 30, stated in the environment-plus-rule format practiced throughout the course.
List each major documented allophone with its conditioning environment, using the phone-phoneme-allophone framework from Chapter 5 and the distributional evidence standard established in Chapters 9 through 18. State whether each pattern is a productive rule or a descriptive tendency, applying the distinction developed in Chapter 31.
Syllable Structure and Phonotactics
Purpose: incorporate the phonotactic profile built in Chapter 31, connecting syllable structure directly to the segmental inventory above.
Restate the variety's basic syllable template and its major positional restrictions, using the onset-nucleus-coda framework from Chapter 19 and the phonotactic-profile work from Chapter 31. Where a source documents syllabic consonants or moraic structure as relevant, summarize that pattern at the introductory level established in Chapter 19.
Relevant Prosodic Systems
Purpose: incorporate only the prosodic systems your Chapter 31 evidence actually supports, following the evidence-first approach that avoids assuming every variety has the same prosodic systems as English.
Report each documented system among lexical stress, rhythm and timing, segmental quantity, lexical tone, pitch accent, and intonation, using the terminology and notation established in Chapters 20 through 22. Mark any system for which no source in your ledger provides evidence as undocumented, following the same three-way distinction used for the segmental inventory.
Connected-Speech Processes
Purpose: incorporate the connected-speech section from Chapter 31, stating each process's status explicitly.
List each documented process using the assimilation, reduction, deletion, epenthesis, resyllabification, and linking categories from Chapter 23, state its conditioning environment, and mark it as obligatory, optional, or style-dependent so a reader can judge when a careful, unreduced form remains acceptable.
Variation and Limitations
Purpose: incorporate the variation statement from Chapter 31 and state, in the same section, what the profile as a whole cannot responsibly claim.
Report each documented source of variation using the regional, social, stylistic, generational, contextual, conservative-or-innovative, and speaker-specific categories from the Master Instructions. State clearly which form, if any, this profile has treated as its reference form, and repeat that this choice is a documentation convenience rather than a judgment about correctness, following the variation policy applied throughout Chapter 31.
Close this section with an explicit limitations statement: name the evidence gaps, the systems left undocumented, and any claim a reader might reasonably expect that the profile deliberately does not make. A bounded profile that states its limits plainly is more useful, and more honest, than one that implies completeness it has not earned.
A limitation you know privately but do not state in the profile is not available to the reader who relies on the document. Write limitations into the profile itself, in plain language, rather than treating them as something the analyst simply keeps in mind.
Broad and Phonetic Sample Transcriptions
Purpose: incorporate the representative sample transcriptions selected in Chapter 31, confirming that each still traces to the source ledger.
Present a small, well-chosen set of sample forms, each illustrating a specific point already made elsewhere in the profile, with a broad transcription and, where the point requires it, a narrow phonetic transcription, following the level-appropriate selection practice from Chapter 24. Do not introduce a new constructed example at this stage; use only forms already verified against your ledger, or clearly label any illustrative form as unverified.
Perception Priorities and Production Priorities
Purpose: present the ranked priorities from Chapter 31 as two focused lists, separating what a learner should prioritize hearing from what a learner should prioritize producing.
Divide your ranked candidate list from Chapter 31 into a perception-priorities list and a production-priorities list, since the two skills do not always share the same ranking; a contrast a learner must reliably hear is not always the same pattern a learner most needs to produce accurately. For each priority, state briefly why it matters, using the contrast, frequency, or intelligibility justification developed in Chapter 31, and avoid ranking a pattern highly merely because it seems unfamiliar or striking to an outside observer.
Technical Self-Audit
Purpose: apply the quality-assurance discipline used throughout the course's production process to your own finished profile before you consider it complete.
- Every IPA symbol matches its intended Unicode character, checked against the confusable-pairs list from Chapter 3 and the Master Instructions.
- Delimiters are used correctly and consistently: slashes for phonemic claims, brackets for phonetic claims, angle brackets for orthographic forms.
- Every example traces to a source in your ledger, with no invented forms presented as verified.
- Every inventory cell, prosodic system, and connected-speech process is marked as confirmed, undocumented, or disputed, with no silent gaps.
- Rule language is used only where the evidence supports a productive rule; tendency language is used elsewhere, following Chapter 31.
- The reference variety is named consistently throughout, with no unlabeled shift to a different variety mid-document.
- The variation statement treats the chosen reference form as a documentation convenience, not a correctness judgment.
- The limitations statement names the profile's actual gaps rather than implying completeness.
- Perception and production priorities are each justified by contrast, frequency, or intelligibility evidence, not by perceived difficulty.
- No instructor notes, source-verification tables, or production metadata have been left inside the learner-facing profile.
Error: Treating the self-audit as a formality performed after the profile is "really" finished, rather than as a required step that can still change the document.
Correction: Run the full checklist before submission, and revise any section the audit flags. A profile that fails its own audit is not yet complete.
Performance Assessment
Purpose: state exactly what you submit to demonstrate capstone mastery.
The completed capstone submission consists of six parts:
| Component | Content |
|---|---|
| Complete written profile | All sections from the language and reference-variety statement through the technical self-audit |
| Accessible reference chart or summary | A condensed one- or two-page version of the consonant chart, vowel chart, and key priorities for quick reference |
| Short oral or recorded explanation | A brief spoken walkthrough of the profile's major findings and limitations, where recording is available |
| Transcription commentary | A short explanation of the decisions behind the sample transcriptions selected in the profile |
| Revision memorandum | A concise account of what changed between an earlier draft and the submitted version, and why |
| Final self-assessment | A short reflection connecting the finished profile back to the self-audit checklist |
What the Profile Cannot Claim
No capstone profile completed at this stage will match the depth of a specialist reference grammar built over years of fieldwork. That is not a shortcoming of the method; it is the expected outcome of a bounded, evidence-based project. A profile that clearly states "no source in this ledger addresses tone sandhi for this variety" has succeeded at exactly the task this course teaches: building a responsible account from available evidence and being honest about where that evidence stops. A profile that quietly fills the gap with a guess has failed the task, however complete it appears on the page.
Capstone Exercises
These exercises work from described profile-drafting situations and prepare you to complete your own capstone submission.
Exercise A — Missing Connective Tissue
A draft profile presents a complete consonant and vowel chart but has no phonotactic or prosodic section. Explain what a reader cannot yet do with this draft and which chapters supply the missing components.
Exercise B — Perception Versus Production Divergence
A contrast is easy for learners to hear but rarely comes up in production because the words that carry it are uncommon. Explain how this pattern might be ranked differently on a perception-priorities list than on a production-priorities list.
Exercise C — Self-Audit in Practice
Running the technical self-audit, you discover that one inventory cell is marked as an attested phoneme but no citation appears in your source ledger. Explain what you must do before the profile can be considered complete.
Exercise D — Bounded Versus Overconfident
Compare a profile that states "tone is undocumented in the available sources" with one that states "this variety has no tone." Explain why these are not equivalent claims and which one the evidence in Exercise C's scenario would actually support if tone had never been investigated.
Common Mistakes
Error: Submitting the individual components from Chapters 29 through 31 side by side without integrating them into one coherent document with a single reference-variety statement and a single limitations section.
Correction: Assemble the components under the unified structure this chapter specifies, cross-referencing sections so a reader can move between the inventory, the phonotactic profile, and the priorities without confusion.
Error: Presenting the finished profile as more complete or more certain than the underlying evidence supports, in order to make the capstone look more impressive.
Correction: Let the self-audit and limitations statement stand as evidence of rigor. A carefully bounded profile that states its limits is stronger work than an overconfident comprehensive claim.
Error: Treating perception priorities and production priorities as automatically identical without checking whether the evidence actually supports the same ranking for both.
Correction: Rank each list independently against its own justification, and note explicitly where the two lists diverge.
Chapter Review
Part A — Assembling the Profile
1. List the components a scope and source-method statement must include.
2. Explain why the inventory chart alone is not a complete phonetic profile.
Part B — Discipline and Limits
1. Explain the difference between an undocumented gap and a confirmed absence, and why a technical self-audit checks for this distinction.
2. Explain why a limitations statement belongs inside the profile rather than only in the analyst's private notes.
Part C — Priorities and Submission
1. Explain why perception priorities and production priorities may be ranked differently for the same pattern.
2. List the six components of the capstone performance assessment.
Cumulative Review
1. From Chapter 29: Explain how the original research plan's questions and source ledger reappear inside the finished capstone profile.
2. From Chapter 30 and Chapter 31: Explain how the confirmed-absence, undocumented-gap, and disputed-cell distinction, first built for the segmental inventory, now governs the entire finished profile.
3. Across the whole course: Explain how the progression from observation in Chapter 1 to a documented capstone profile in this chapter reflects the observe-distinguish-describe-produce-symbolize-read-transcribe-analyze-map progression from the Master Instructions.
Self-Check
Before submitting your capstone profile, confirm that you can do the following without looking at your notes:
- State the profile's reference variety and scope in one or two sentences.
- Explain how the segmental inventory, phonotactic profile, and prosodic profile connect to one another.
- Identify at least one system marked as undocumented in your own profile and explain why it is marked that way rather than marked as absent.
- State your top perception priority and top production priority and justify each with contrast, frequency, or intelligibility evidence.
- Run the technical self-audit checklist against your own draft and identify any item it flags.
- Explain, in one sentence, what your profile deliberately does not claim.
If any of these tasks are difficult, revisit the relevant section of this chapter, or return to Chapters 29 through 31 for the underlying component before finalizing your submission.
Answer Key (click to expand)
Capstone Exercises — Exercise A
Without a phonotactic or prosodic section, a reader can see which sounds occur in the variety but cannot tell how those sounds combine into syllables or which syllables carry prominence, tone, or pitch accent. The missing components come from Chapter 31, which builds the phonotactic profile from Chapter 19's onset-nucleus-coda framework and the prosodic profile from Chapters 20 through 22.
Capstone Exercises — Exercise B
A contrast that is perceptually easy to hear but occurs in few actual words may rank high on a perception-priorities list, where the goal is reliable discrimination, but rank lower on a production-priorities list, where frequency and communicative consequence in real use carry more weight. The two lists are not required to match.
Capstone Exercises — Exercise C
Before the profile can be considered complete, the analyst must either locate and add the missing citation to the source ledger or downgrade the chart entry to an undocumented gap or a clearly labeled tentative claim. An inventory entry without a traceable source fails the self-audit and cannot remain marked as confirmed.
Capstone Exercises — Exercise D
"Tone is undocumented in the available sources" reports the actual state of the evidence: no source has addressed the question. "This variety has no tone" is a positive claim that requires its own supporting evidence, such as a source that explicitly states the variety is non-tonal. If tone had never been investigated, only the undocumented framing is supportable; the two statements are not interchangeable.
Chapter Review — Part A
1. A scope and source-method statement should name the language and reference variety, restate the research questions from the Chapter 29 proposal, identify the sources by type and priority, and state what the evidence does and does not allow the profile to claim. 2. The inventory chart shows which sounds occur but not how they combine into syllables, how prominence and pitch are organized, how careful forms change in connected speech, or how the variety varies by speaker and context; a complete profile requires the phonotactic, prosodic, connected-speech, and variation sections as well.
Chapter Review — Part B
1. An undocumented gap means no source addresses a cell or system, while a confirmed absence means a source explicitly states the feature does not occur; the self-audit checks this distinction because collapsing the two into a single blank or a single claim misrepresents the evidence either way. 2. A limitation known only privately is unavailable to any reader relying on the document, so stating limitations inside the profile is necessary for the document itself to be honest and useful.
Chapter Review — Part C
1. Perception priorities are ranked by what a learner most needs to reliably hear and discriminate, while production priorities are ranked by what a learner most needs to accurately produce in real communication; a pattern's frequency or salience can differ between these two tasks, so the same pattern may rank differently on each list. 2. The complete written profile, an accessible reference chart or summary, a short oral or recorded explanation, a transcription commentary, a revision memorandum, and a final self-assessment.
Cumulative Review
1. The research questions and source ledger from Chapter 29 reappear directly in the capstone's scope and source-method statement, which restates the questions and names the same sources by type and priority, showing that the research plan governed the entire project rather than being a discarded preliminary step. 2. The three-way distinction built in Chapter 30 for empty inventory cells, and extended to prosodic systems in Chapter 31, now governs every component of the finished profile: consonants, vowels, phonotactics, prosody, and connected speech are all subject to the same requirement that a gap in the evidence be marked as a gap rather than resolved by assumption. 3. The course moved learners from neutral observation of speech in Chapter 1, through description and symbolization in the consonant and vowel chapters, through production and transcription in Part V, to the analytical mapping method of Part VI, culminating in a documented capstone profile that requires every earlier stage of the progression to be in place before the final synthesis is possible.
Course Complete
What You Can Now Do
You can now synthesize articulatory, auditory, phonological, and acoustic evidence into a single coherent phonetic profile; apply IPA consistently across every component of that profile; explain the limits of your selected analysis; distinguish established facts from analytical decisions throughout a substantial document; present variation respectfully; prioritize perception and production goals by contrast and communicative consequence; audit a finished profile for technical and editorial accuracy; and revise a complete profile using feedback.
