Comprehensive Study Guide: Articulatory Phonetics, Speech Anatomy, and Phonetic Structure

Course Mechanics, Logistics, and Exam Details

• Textbook Exercise vs. Assignment Conventions:

  • In-text exercises embedded within chapters are denoted by decimals (e.g., $2.1$ or $2.5$); these are designated for completion during class.
  • Graded turned-in assignments are denoted by hyphens (e.g., $2-2$ or $4-1$).

• Exam 1 Administration & Availability:

  • Timeframe: Opens online immediately following class and closes on Sunday, September 13th at $11:59\,\text{PM}$. It can be taken at any time within this open window.
  • Class Schedule Note: No class meeting on Friday to allow students time to complete the online examination.
  • Rationale for Online Format: In-person testing for phonetics/genetics creates significant acoustic distractions due to embedded audio/video listening requirements (e.g., students wearing headphones, humming, singing to themselves, clapping, or tapping).

• Exam 1 Structure and Parameters:

  • Question Count: $35$ to $45$ questions.
  • Total Points: $100$ points.
  • Scope: Chapters 1, 2, and 3.
  • Question Types: Fill-in-the-blank, multiple choice, true/false, and matching.
  • Time Limit: $50$ minutes.
  • Proctoring Requirements: LockDown Browser with Web Monitor.
  • Permitted Materials: One blank piece of paper and a pencil (must be shown to the camera during the environment setup scan).
  • Technical Advice: Strong, stable Wi-Fi is required to ensure smooth loading of test items and monitoring video feed.

• Academic Support & Office Hours:

  • Graduate Assistant Review: Graduate Assistant Bella conducts Zoom review sessions prior to exams.
  • Instructor Office Hours: Mondays and Wednesdays from $8:30\,\text{AM}$ to $9:00\,\text{AM}$ (prior to class) for extra practice and questions.

Articulatory Phonetics & Oral Cavity Structures

• Articulatory Expectation for Testing:

  • Full transcription mastery of specific phoneme symbols (e.g., $/f/$, $/\int/$) is not expected on Exam 1.
  • Students must identify the precise articulators used to produce specific sounds (e.g., identifying that making an $/f/$ sound relies on the lips and teeth).

• Classification of Articulatory Structures and Places:

  • Labiodentals: Sounds produced using the lips and teeth (e.g., $/f/$, $/b/$ as referenced in introductory context).
  • Interdentals: Sounds produced with the tongue placed between the teeth (e.g., the "th" sounds in "think" and "that").
    • Voiceless Interdental: The "th" sound in think. When producing this sound, placing hands on the thyroid notch reveals zero vocal fold vibration.
    • Voiced Interdental: The "th" sound in that. Active vocal fold vibration is physically felt at the thyroid notch.
  • Alveolars: Sounds produced by placing the tongue at or near the alveolar ridge (the bony ridge located directly behind the upper front teeth).
    • Includes $/t/$, $/d/$, $/l/$, $/n/$, $/s/$, and $/z/$.
    • Note: For $/s/$ and $/z/$, the tongue may not always visibly touch the alveolar ridge, but they are categorized phonetically as alveolar sounds.
  • Palatals: Sounds produced at the hard palate (the vaulted bony roof of the mouth located posterior to the alveolar ridge).
    • Includes the "sh" sound in shift and the "y" sound ($/j/$) in you.
  • Velars: Sounds produced at the velum / soft palate (the soft muscular area behind the hard palate).
    • Includes $/k/$, $/g/$, and $/\eta/$ ("ng").
  • Uvula: The small fleshy tissue hanging down at the back of the soft palate.
    • Used to produce phonemes in languages like French and Arabic.
    • English possesses no uvular phonemes.
  • Glottals: Sounds produced at the glottis (the space between the vocal folds located within the larynx).
    • Includes the voiceless phoneme $/h/$ (e.g., hi).
    • Must not be confused with $/w/$.

• Anatomy and Subdivisions of the Tongue (Lingual Articulator):

  • The primary articulator for all vowels and the principal active articulator in the oral cavity for overall speech production.
  • A muscle supported by bony structures: the mandible (jawbone) and the hyoid bone (located in the upper neck).
  • Articulates against the lips, teeth, alveolar ridge, hard palate, and velum.
  • Five Distinct Anatomical Parts:
    1. Root
    2. Tip
    3. Blade
    4. Body Front
    5. Body Back
  • Dorsum: The term used to refer to the entire main body of the tongue.

Vocal Fold Dynamics and Acoustic Theories

• Glottal States and Vocal Fold Action:

  • Abduction: Vocal folds are pulled open / separated. Allows normal quiet respiration.
  • Adduction: Vocal folds are drawn together / closed.
  • Rapid adduction and subglottal air pressure build-up cause the vocal folds to vibrate rapidly, producing voicing/phonation. Complete sustained closure prevents air passage and stops respiration.

• Source-Filter Theory:

  • A foundational speech science theory explaining how vocal tract resonances modify acoustic energy.
  • Source: The raw sound energy generated by air pressure from the lungs and vocal fold vibration.
  • Filter: The modification of sound produced by changing the shape and resonances of the vocal tract using articulators (tongue, lips, jaw, velum).

• Bernoulli Principle:

  • Explains the aerodynamic physical dynamic contributing to vocal fold adduction during phonation.
  • An increase in airflow velocity through a narrow constriction (the space between the vocal folds) causes a localized drop in air pressure.
  • This pressure drop creates a suction effect that draws the vocal folds back together during cyclic vibration.

• Resonance:

  • The inherent capability of any vibrating body or acoustic cavity to vibrate at specific natural frequencies.
  • Speech sound production relies on altering tongue and articulator configurations to change vocal tract resonances, shaping acoustic vibrations that travel through air to be perceived by listeners.

Syllable Structure, Morphemes, and Phonetic Definitions

• Essential Phonetic Definitions:

  • Phonetics: The formal study of the production and perception of speech sounds.
  • Grapheme: A printed alphabet letter or group of letters representing a sound in written language.
  • Allophone: A variant pronunciation or phonetic execution of a single phoneme that does not alter word meaning (e.g., initial light $/l/$ vs. final dark $/l/$ in little, or released vs. unreleased $/p/$).
  • International Phonetic Alphabet (IPA): The standardized alphabetic system used to transcribe speech sounds.

• Syllable Anatomy:

  • Onset: All consonant sounds that precede the vowel nucleus in a single syllable (can be a single consonant or a consonant cluster).
  • Nucleus: The core vowel element required in every syllable.
  • Coda: All consonant sounds that follow the vowel nucleus in a single syllable.
  • Open Syllable: A syllable ending in a vowel sound that contains no coda (e.g., play).
  • Closed Syllable: A syllable ending in a consonant sound that does contain a coda.

• Morphemes and Minimal Pairs:

  • Bound Morpheme: A linguistic unit of meaning that cannot stand alone as an independent word and must attach to another morpheme (e.g., the suffix "-s" in likes).
  • Minimal Pair: Two words that differ by only one phoneme in the exact same position and contain the exact same total count of phonemes.
    • Valid Example: mood vs. mad (both have $3$ phonemes; differ only in the medial vowel).
    • Invalid Example: mood vs. crude (mood contains $3$ phonemes, whereas crude contains $4$ phonemes; mismatched phoneme counts invalidate minimal pairs).
    • Invalid Example: moon vs. mat (differs by two phoneme substitutions).

Exam Review and Practice Exercises

• Respiration Ratios:

  • Speech Respiration Cycle: $10\%$ inhalation and $90\%$ exhalation.
  • Quiet/Resting Respiration Cycle: $40\%$ inhalation and $60\%$ exhalation.

• Anatomical & Supralaryngeal Systems:

  • Maxilla: The upper jaw bone.
  • Mandible: The lower jaw bone.
  • Supralaryngeal System: Structures located above the larynx, comprising the oral cavity, nasal cavity, and pharynx.
  • Subdivisions of the Pharynx:
    • Oropharynx: Section joining the oral cavity and pharynx.
    • Nasopharynx: Section joining the nasal cavity and pharynx.
    • Laryngopharynx: Section of the pharynx directly adjoining the larynx.

• Phonetic Structure & Stress Analysis Cases:

  • Analysis of ledger:
    • Grapheme count: $6$ letters (l-e-d-g-e-r).

    • First syllable onset: $/\int/$ ("sh").
  • Analysis of baseball:
    • Second syllable onset: $/b/$.
  • Primary Stress Placement Exercises:
