| 6 | +# Consonants |
| 7 | + |
| 8 | +## How we classify consonants |
| 9 | +Consonants are described by **place of articulation** (where in the vocal tract the constriction is), **voicing** (vocal folds vibrating or not), **manner of articulation** (how narrow/complete the constriction is), and **oral vs. nasal** airflow. |
| 10 | + |
| 11 | +### Places of articulation (English examples) |
| 12 | +- **Labial** |
| 13 | + - **Bilabial**: [p] *pit*, [b] *bit*, [m] *mitt* |
| 14 | + - **Labiodental**: [f] *fan*, [v] *van* |
| 15 | +- **Coronal** |
| 16 | + - **Interdental**: [θ] *breath*, [ð] *breathe* |
| 17 | + - **Alveolar**: [t] *tip*, [d] *dip*, [s] *sip*, [z] *zip*, [n] *nip*, [l] *lip*, [ɹ] *rip* |
| 18 | + - **Alveo-palatal**: [ʃ] *Asher*, [ʒ] *azure*, [tʃ] *chip/search*, [dʒ] *judge* |
| 19 | + - **Palatal**: [j] *yacht* |
| 20 | +- **Dorsal** |
| 21 | + - **Velar**: [k] *pick*, [g] *pig*, [ŋ] *ping* |
| 22 | + - **Labiovelar**: [w] *wig* |
| 23 | +- **Glottal**: [h] *head*. |
| 24 | + |
| 25 | +### Voicing |
| 26 | +Some pairs differ **only** in voicing while oral articulation is the same (e.g., [s] vs. [z]). A quick test is whether you feel vocal-fold “buzz.” |
| 27 | + |
| 28 | +### Manners of articulation |
| 29 | +- **Stops**: complete oral closure -> [p b t d k g] |
| 30 | +- **Fricatives**: narrow constriction with turbulent airflow -> [f v θ ð s z ʃ ʒ h] |
| 31 | +- **Affricates**: stop + fricative release -> [tʃ dʒ] |
| 32 | + The set **stops+fricatives+affricates** are **obstruents**. |
| 33 | + |
| 34 | +- **Nasals**: oral closure, airflow through nose -> [m n ŋ] |
| 35 | +- **Approximants**: relatively open oral tract -> [l ɹ w j] |
| 36 | + **Nasals+approximants** are **sonorants**; in English, sonorants are voiced. |
| 37 | + |
| 38 | +> **Quick practice:** Transcribe and label the consonants in your first name. |

| 43 | +# Vowels |
| 44 | + |
| 45 | +## How we classify vowels |
| 46 | +Vowels are described by **height** (tongue high–low), **backness** (front–back), and **lip rounding**. These dimensions are summarized in the **vowel quadrilateral**. |
| 47 | +### American English vowel inventory (high-level) |
| 48 | +- **Front**: [i] (*heed*), [ɪ] (*hid*), [eɪ] (*hayed*), [ɛ] (*head*), [æ] (*had*) |
| 49 | +- **Back**: [u] (*who’d*), [ʊ] (*hood*), [oʊ] (*hoed*), [ɔ] (*hawed*, not in all dialects), [ɑ] (*hod*) |
| 50 | +- **Central**: [ʌ] (*cut*), [ə] (*sofa*, unstressed “schwa”) |
| 51 | +Rounded back vowels include [u ʊ oʊ ɔ]. |
| 52 | + |
| 53 | +### Diphthongs vs. monophthongs |
| 54 | +- **Diphthongs**: vowel quality moves during the syllable -> [eɪ], [oʊ], [aɪ] (*bite*), [aʊ] (*bout*), [ɔɪ] (*boy*) |
| 55 | +- **Monophthongs**: relatively stationary tongue configuration. |
| 56 | +### Lax vowels and word-final position |
| 57 | +The **lax** set [ɪ ɛ æ ʊ] (and [æ], [ɛ]) have distributional constraints in American English-for instance, they generally do **not** appear word-finally without a following consonant. |
| 58 | + |
| 59 | +> **Quick practice:** Transcribe and label the vowels in your first name. |

| 63 | + |
| 64 | +# Syllables & Stress |
| 65 | + |
| 66 | +## What is a syllable? |
| 67 | +A **syllable** minimally contains a vowel; many English syllable shapes combine consonants and vowels (e.g., **CV** *tea*, **CCV** *glue*, **CVC** *pot*, **CCVCC** *stink*). Complex clusters occur in words like *sixths* [sɪksθs], *twelfths* [twɛlfθs]. |
| 68 | + |
| 69 | +### Parts of a syllable |
| 70 | +- **Nucleus** (vowel) |
| 71 | +- **Onset** (consonants before nucleus) |
| 72 | +- **Coda** (consonants after nucleus). |
| 73 | + |
| 74 | +### Syllable-building heuristics (English) |
| 75 | +1. **Nucleus Rule:** create a syllable for every vowel/diphthong. |
| 76 | +2. **Onset Rule:** maximize onset consonants-but only sequences that can begin a word may be onsets (*e.g.*, [ŋ], /ktr/ cannot start English words). |
| 77 | +3. **Coda Rule:** leftover consonants fill the coda. |
| 78 | +Try parsing **conflict** and **manuscript** using these rules. |
| 79 | + |
| 80 | +## Phonotactics (what sequences are allowed) |
| 81 | +- English allows clusters but not all combinations: *[ktɑm]* is ill-formed in English (though cf. Polish [kto] *‘who’*); *strict* [stɹɪkt] is fine, but *[stlɪtk]* is not. |
| 82 | +- **Nasal place assimilation** before oral stops: *romp* [ɹɑmp], *lent* [lɛnt], *skunk* [skʌŋk]. |
| 83 | +- Some segments occur only in onsets or only in codas: [tʌŋ] ‘tongue’ vs. *[ŋʌt]*; [hɪm] ‘him’ vs. *[mɪh]*. |
| 84 | +- Some vowels require codas; **lax** vowels [ɪ ɛ æ ʊ] cannot appear word-finally without a following consonant (e.g., [pɛg] but not *[pɛ]). |
| 85 | + |
| 86 | +## Lexical stress |
| 87 | +English contrasts stress positions: **OBject** (noun) vs. **obJECT** (verb); **CONflict** (n) vs. **conFLICT** (v). Prominence typically involves higher pitch, longer duration, and greater intensity on the stressed vowel. |
| 88 | + |
| 89 | +### Common stress patterns |
| 90 | +- **Two syllables:** **Trochee** (first-syllable stress) *never, window, sprinkle*; **Iamb** (second-syllable stress) *indeed, perhaps, amuse*. |
| 91 | +- **Three syllables:** **Final** (*introduce, guarantee, comprehend*), **Penultimate** (*bandana, December, regardless*), **Antepenultimate** (*excellent, festival, happily*). |
| 92 | +> **Names & stress:** Try naming examples that fit each pattern; note why some shortened forms are impossible (*Jennifer -> Jen*, but not *Je*; *Alfred -> Al/Alf*, but not *Alfr*). |
