Phonology in Linguistics

From Sound to Meaning

  • Linguistic competence enables the decoding of continuous soundwaves into ideas/messages.

  • Not all languages primarily use sound; sign languages will be discussed later.

Levels of Analysis in Linguistics

  • Analysis occurs at multiple levels:

    • Break Speech Signal: Discrete speech sounds are identified.

    • Meaningful Units: Grouping of speech sounds into words.

    • Phrases and Sentences: Words are combined to form interpretable sentences.

  • Focus will be on phonology: the study of sound structure in language.

Speech Sounds

  • Every language has a unique set of speech sounds called phonemes.

  • A phoneme is defined as the smallest sound unit that alters the meaning of a word.

Understanding Phonemes

  • Example: Changing the last sound of "map" ([mæp]) to a "t" sound produces "mat" ([mæt]).

  • Distinction from letters: phonemes are represented in brackets [ ].

    • Example: [p] for the p sound.

Minimal Pairs

  • Words differing by one phoneme are termed minimal pairs.

    • Examples in English:

    • pop vs. cop → [pɑp] vs [kɑp]

    • cat vs. kit → [kæt] vs. [kɪt]

    • fail vs. kale → [feɪl] vs. [keɪl]

Phoneme Variations

  • Pronunciation can vary without altering the word:

    • Example: [p] can be released (with air) or unreleased (without air).

  • Variations don’t create new words in English.

The International Phonetic Alphabet (IPA)

  • The IPA allows precise writing of phonemes.

  • Each sound phoneme across languages is assigned a unique symbol.

  • Approx. 300 phonemes exist in the full IPA.

Limitations of Roman Alphabet

  • The Roman alphabet is insufficient for phoneme representation:

    • One-to-one correspondence in IPA contrasts with the Roman system (e.g., multiple sounds for one letter).

    • Example: "GHOTI" demonstrates spelling inconsistencies.

Practical Use of IPA

  • Phonemes represented in IPA:

    • cat: [kæt]

    • map: [mæp]

    • book: [bʊk]

  • Some sounds represented by single letters in English require two symbols in IPA (e.g., sh: [ʃ], th: [θ]).

Articulation in Phonology

  • Phonemes differentiated by articulation: how vocal tract parts move.

  • Active articulators: tongue, lips, velum (soft palate).

Difference between Consonants and Vowels

  • Consonants: High closure in the vocal tract.

  • Vowels: Relatively open articulation, produced as tones.

  • Vowels are louder and easier to sing; consonants are more turbulent.

Articulatory Features

  • Consonants classified by:

    • Place of articulation (location of constriction)

    • Manner of articulation (how constriction occurs)

    • Voicing (vocal cords vibrating or not)

Phonotactics

  • Each language has rules for phoneme combinations termed phonotactics.

  • Certain phoneme sequences are disallowed (e.g., *bnick is not a valid English word).

Examples of Phonotactic Restrictions

  • Plural endings in English (e.g., -s) may lead to sound changes:

    • toe [toʊ] → toes [toʊz (or toʊs)]

    • cat [kæt] → cats [kætz (or kæts)]

Phonological Rules

  • Rule example: [z] → [s] / voiceless consonant __

    • Applies to plural forms of nouns where voicing and sound sequence matter.

Case Study: Writer vs. Rider

  • Flapping Rule: [t] and [d] become [ɾ] before unstressed vowels.

  • Vowel Lengthening Rule: Vowels lengthen before voiced consonants.

    • Example: writer [raɪtər] becomes [raɪɾər], rider [raɪdər] becomes [raɪ:ɾər].

Summary of Key Concepts

  • Words consist of phonemes; minimal pairs help identify them.

  • IPA is used for accurate phoneme representation.

  • Phonotactics govern possible phoneme sequences.

  • Phonological rules dictate how underlying representations change into surface forms.
