Introduction to General Linguistics: Phonetics 1 - Consonants

Introductions to Linguistics

• Definition: Linguistics is defined as the scientific study of language.

Core Areas of Linguistics

• Phonetics: Study of how speech sounds are produced and processed.

• Phonology: Organization of sounds into larger linguistic units.

• Morphology: Formation of words and their internal structures.

• Syntax: Sentence construction from words.

• Semantics: Characterization and prediction of sentence meanings.

• Pragmatics: Interpretation based on context.

• Discourse Analysis: Structuring of conversations and texts.

Other Sub-disciplines of Linguistics

• Typology: Comparing differences and commonalities across languages.

• Neurolinguistics: Brain's role in language usage.

• Psycholinguistics: Individual language acquisition and processing.

• Evolutionary Linguistics: Development of language abilities in humans.

• Historical Linguistics: Language change over time.

• Sociolinguistics: Language variation in social contexts.

Application of Linguistics

• Applied Linguistics Branches:

  • Language teaching

  • Language documentation

  • Computational linguistics

  • Clinical linguistics

  • Forensic linguistics

Phonetics Overview

• Phonetics Definition:

  • From Greek φωνή (“sound”), focuses on the physical mechanisms of speech sounds.

• Branches of Phonetics:

  • Articulatory Phonetics: Physiology of speech production.

  • Acoustic Phonetics: Physical properties of sound waves.

  • Auditory Phonetics: Auditory perception and processing.

Phonetic Transcription

• Need for Standardized Representation:

  • Existing orthographies vary in sound representation.

  • A canonical system is necessary for accurate description.

• International Phonetic Alphabet (IPA):

  • An established standard for representing sounds using 107 letters and 44 diacritics.

  • Updated to reflect new knowledge but mostly stable since 1989.

The Sound-Producing System

• Overview of Sound Production:

  • Involves airflow movement, typically generated by the lungs.

  • Three Stages of Sound Production:

  • Airstream Mechanism: Generation of airflow (usually pulmonic, from lungs).

  • Phonation: Modification of airflow in the larynx.

  • Articulation: Flow modification as it travels through the pharynx and vocal cavities.

• Types of Airstream:

  • Egressive: Airflow directed away from the body (most common).

  • Ingressive: Airflow directed inward.

Phonation

• Mechanics of Phonation:

  • Involves airflow modification within the larynx.

  • The lungs push air through the trachea and larynx, where various anatomical structures influence sound.

• Vocal Folds:

  • Two tissue infoldings stretching across the larynx; responsible for voice production through vibration.

• Glottal States: Different configurations of the vocal folds resulting in various sounds:

  • Voiced Sounds: Vocal folds are together but relaxed (e.g., ).

  • Voiceless Sounds: Vocal folds apart (e.g., ).

  • Whisper: Parts of vocal folds together, producing turbulence.

  • Murmur: Vocal folds together allowing air to pass with slight vibration.

  • Creaky Voice: Restricted vibrations create a specific sound.

Articulation

• Active vs Passive Articulators:

  • Active: Movable parts like the tongue.

  • Passive: Stationary structures like palate and ridge.

• Articulatory Locations and Examples:

  • Bilabial: Lower lip against upper lip (e.g.,

    , ).

  • Dental, Alveolar, Palate, Velar, Uvular, Pharyngeal: Each with specific examples.

Consonants Classification

• Major Classes of Sounds:

  • Consonants: Created with airflow obstruction.

  • Vowels: No obstruction in airflow.

  • Glides/Semi-vowels: Properties of both consonants and vowels.

• Places of Articulation: Distinct points where sound is produced.

• Manners of Articulation: How airflow is obstructed:

  • Examples include plosives, trills, taps, fricatives, affricates, approximants, laterals.

Consonant Sounds Overview

• Systematic format for wireless consonants:

  • Standardized naming conventions (phonation + place + manner).

• Common Consonant Samples:

  • 128 consonants occurring in various languages.

Examples of Consonant Types

• Plosives:

  • Voiceless: [p], [t], [k]

  • Voiced: [b], [d], [g]

• Nasals: [m], [n], [ŋ]

• Fricatives:

  • Voiceless: [f], [s], [ç], [x].

  • Voiced: [v], [z], [ð].

• Approximants: [r], [l], [y], [w].

Specialized Consonants

• Implication of Aspiration and Nasality: E.g., the presence of aspiration in certain plosives indicates nuanced language characterizations.

• Prenasalization, Secondary Articulation, Double Articulation: Special articulatory conditions producing unique sounds.
