Phonetics Exam 1 Comprehensive Review Flashcards

Vocabulary flashcards covering core definitions, transcription principles, syllable structures, and speech anatomy from Phonetics Exam 1 review materials.

Phonetics

The study of how speech sounds are physically produced, transmitted, and perceived.

Phonology

The systematic organization of speech sounds in the production of language, including the system and rules for how sounds are organized in a language.

Phoneme

An individual speech sound that can distinguish or change meaning in a language.

Grapheme

A written letter or letter combination that represents a speech sound.

Morpheme

The smallest unit of language that carries meaning.

Free Morpheme

A morpheme that can stand alone as an independent word, such as 'tree', 'chair', or 'desk'.

Bound Morpheme

A morpheme that cannot stand alone and must attach to another morpheme, such as the '-s' in 'trees' or 're-' in 'renew'.

Allograph

Different letter sequences or spelling patterns that represent the same speech sound, such as the /u/ sound in 'blue', 'through', and 'fruit'.

Digraph

A pair of letters that represent a single speech sound, such as 'sh' in 'Shelly'.

Minimal Pairs

Two words that differ by exactly one phoneme in the same position while maintaining the same total number of phonemes.

Allophone

A variation in how a single phoneme is produced that does not change the meaning of the word.

Complementary Distribution

Allophonic variation where the specific pronunciation of a speech sound is determined by its surrounding phonetic environment, such as light /l/ versus dark /l/.

Free Variation

Allophonic variation where the choice of pronunciation depends on speaker habit or preference rather than being dictated by the phonetic environment, such as released versus unreleased final /p/.

Dialect

Regional, social, or ethnic group variations in speech sound production and pronunciation that do not alter the fundamental principles of phonetic transcription.

International Phonetic Alphabet (IPA)

A standardized system of symbols used to represent individual speech sounds consistently across languages.

Syllable

A basic building block of language composed of a vowel alone or a vowel in combination with one or more consonants.

Onset

All consonant phonemes that precede the vowel nucleus in a single syllable.

Rhyme

A structural segment of a syllable consisting of an obligatory nucleus and an optional coda.

Nucleus

The core segment of a syllable carrying the greatest acoustic energy, typically consisting of a vowel or a syllabic consonant.

Coda

All consonant phonemes that follow the vowel nucleus in a single syllable.

Open Syllable

A syllable that ends with a vowel phoneme and contains no coda.

Closed Syllable

A syllable that ends with a consonant phoneme (coda).

Diphthong

A single vowel phoneme that involves continuous movement between two distinct vowel articulatory positions.

Broad Transcription

Phonemic transcription of speech that uses virgules / / to transcribe speech sounds without capturing fine allophonic variations.

Narrow Transcription

Detailed phonetic transcription that uses square brackets [ ] and diacritical marks to capture specific allophonic variations and individual articulation traits.

Lexical Stress

The primary acoustic emphasis placed on a specific syllable in a multisyllabic word, characterized by longer duration, higher fundamental pitch, and greater loudness.

Syntax

The set of structural rules governing sentence construction in a language.

Morphology

The linguistic rule system governing the structure and formation of words.

Semantics

The subfield of linguistics concerned with the study of meaning in language.

Pragmatics

The linguistic domain governing the social use of language and communicative context.

Speech Breathing Ratio

The respiratory cycle ratio during speech production, consisting of $10\%$ inhalation and $90\%$ exhalation.

Resting Breathing Ratio

The quiet respiratory cycle ratio consisting of $40\%$ inhalation and $60\%$ exhalation.

Larynx

The cartilaginous structure commonly known as the voice box, situated superior to the trachea, whose primary biological function is airway protection and subglottic pressure maintenance.

Phonation

The production of voice created by the cyclical vibration of the vocal folds.

Vocal Fold Adduction

The movement that brings the vocal folds together (closing), occurring during voicing, phonation, and coughing.

Vocal Fold Abduction

The movement that draws the vocal folds apart (opening), occurring during normal respiration and the production of voiceless phonemes.

Fundamental Frequency ($f_0$)

The baseline rate of vocal fold vibration that dictates perceived vocal pitch, averaging approximately $125\,\text{Hz}$ in adult males and $215\,\text{Hz}$ in adult females.

Bernoulli Effect

The aerodynamic principle that contributes to vocal fold adduction during phonation.

Source Filter Theory

The theoretical framework describing how raw acoustic sound produced at the larynx is modified by changes in the resonance of the vocal tract filter.

Velum

The soft palate that acts as a muscular valve, elevating to seal off the nasopharynx for oral sounds and lowering to allow airflow through the nasal cavity for nasal sounds.

Laryngopharynx

The most inferior division of the pharynx where the larynx and pharynx join.

Oropharynx

The middle division of the pharynx connecting the back of the oral cavity and tongue base to the throat.

Nasopharynx

The superior portion of the pharynx that connects directly to the posterior nasal cavity.

Articulation

The movement and physical contact of speech structures to modify vocal tract shape and produce speech sounds.

Bilabial Consonants

Consonant sounds produced using both lips together, including /p/, /b/, /m/, and /w/.

Labiodental Consonants

Consonants produced through contact between the lower lip and upper front teeth, specifically /f/ and /v/.

Alveolar Ridge Consonants

Speech sounds articulated with the tongue tip or blade touching or approaching the ridge behind the upper front teeth, including /t/, /d/, /l/, /n/, /s/, and /z/.

Velar Consonants

Consonants articulated with the back of the tongue against the soft palate, including /k/, /g/, and /ŋ/.

Voiced Phonemes

Speech sounds generated with active vocal fold vibration in the larynx, including all English vowels and consonants such as /l/, /d/, /v/, /z/, /m/, and /n/.

Voiceless Phonemes

Speech sounds produced without vocal fold vibration in the larynx, such as /t/, /f/, /s/, and /h/.

Vocal Tract Anatomy

The biological structures of the head and neck involved in respiration and speech production.

Linguistic Domains of Speech and Language

The major areas of study within speech and language structure and use.

Vowel Phonetic Symbols

IPA symbol representations and corresponding example words for selected English vowel sounds.

Consonant Phonetic Symbols

IPA symbol representations and corresponding example words for selected English consonant sounds.
