1. Defining Articulation
In phonetics, articulation refers to the specific physical configuration of the vocal tract during speech. This configuration is shaped by the complex interaction of mobile articulators (such as the tongue, lips, and lower jaw) with static structures (like the alveolar ridge, hard palate, and velum).
2. Primary vs. Secondary Articulations
To fully analyze a speech sound, linguists distinguish between primary and secondary articulatory gestures.
🔥 Primary vs. Secondary Articulation
| Category | Definition & Examples |
|---|---|
| Primary Articulation | Defines the core location and manner where the speech sound is generated. Example: An apico-alveolar sound involves the tongue tip (apex) contacting the alveolar ridge (e.g., English /t/ or /d/). |
| Secondary Articulation | An additional, simultaneous configuration created by other articulators while the primary articulation shapes the core sound. |
Notable Types of Secondary Articulation
- Palatalization: Front of the tongue is raised toward the hard palate (e.g., Russian "soft" consonants).
- Velarization: Back of the tongue is raised toward the velum (e.g., the "dark l" [ɫ] in English "pull").
- Labialization: Lip rounding is added to another articulation (e.g., /kw/ in "queen").
- Glottalization: Constriction of the vocal cords (e.g., the glottal stop [ʔ] in the Cockney pronunciation of "butter").
- Nasalization: Simultaneous oral and nasal airflow (e.g., French nasal vowels like [ɑ̃]).
3. Common Places of Articulation
The "Place of Articulation" describes exactly where in the vocal tract the obstruction of airflow occurs.
🔥 Places of Articulation (Active & Passive)
| Place | Action & English Examples |
|---|---|
| Bilabial (Exo-labial) | Outer surface of both lips is used. Examples: [p], [b], [m]. |
| Dental | Tongue touches the upper teeth. Examples: [θ] ("think"), [ð] ("this"). |
| Alveolar | Tip or blade of the tongue contacts the alveolar ridge. Examples: [t], [d], [s], [z]. |
| Post-alveolar | Articulation just behind the alveolar ridge. Examples: [ʃ] ("shoe"), [ʒ] ("measure"). |
| Palatal | Front of the tongue touches the hard palate. Example: [j] ("yes"). |
| Velar | Back of the tongue touches the soft palate (velum). Examples: [k], [g], [ŋ] ("sing"). |
| Glottal | Produced at the vocal cords. Examples: [h], [ʔ] ("uh-oh"). |
Note on Tongue Anatomy: Apical means using the tip of the tongue (clear [t]). Laminal means using the blade. Radical means using the root.
4. Manner of Articulation (The Stricture Continuum)
While "Place" tells us where the sound is made, the "Manner of Articulation" tells us how the airflow is obstructed. This is categorized by a systematic progression based on the degree of stricture (the extent of obstruction to the airflow).
🔥 Exam Focus: The Chronological Sequence of Stricture
The progression moves from the highest level of closure (complete blockage) to the least (open airflow). You must know this exact sequence for UGC NET questions.
🔥 The Progression: Highest to Least Closure
| Manner (Stricture Level) | Definition & Airflow Action |
|---|---|
| 1. Plosives (Stops) | Complete closure followed by a sudden release of air, producing a distinctive burst (e.g., /p/, /b/, /k/). (🔥 Asked in Exam) |
| 2. Affricates | Begins with complete closure, but transitions into a slow, friction-filled release (e.g., /tʃ/ in "church"). (🔥 Asked in Exam) |
| 3. Fricatives | Involves the close approximation of articulators that creates audible, continuous friction without fully blocking the airstream (e.g., /s/, /f/, /v/). (🔥 Asked in Exam) |
| 4. Approximants | Articulators are positioned with open approximation, allowing airflow without any friction, resulting in smoother, vowel-like qualities (e.g., /w/, /j/, /l/). (🔥 Asked in Exam) |
| 5. Trills and Taps | Intermittent closure. A trill occurs when an articulator is held loosely and close to another, setting it into rapid vibration (e.g., rolled /r/). (🔥 Asked in Exam) |
5. Frequently Asked Questions
What is the difference between Place and Manner of Articulation?
"Place of Articulation" refers to the specific anatomical location in the vocal tract where airflow is obstructed (e.g., lips, teeth, palate). "Manner of Articulation" refers to how severely the airflow is obstructed (e.g., completely stopped, restricted causing friction, or flowing smoothly).
What characterizes a Fricative sound?
A fricative is produced by the "close approximation" of two articulators. They are brought very close together, forcing air through a narrow channel, which creates continuous, audible friction (e.g., the /f/ or /s/ sounds).
How does a Plosive differ from an Affricate?
Both begin with a complete closure of the airstream. However, a Plosive releases the air suddenly with a burst or "pop" (like /p/ or /t/). An Affricate releases the air slowly, transitioning into friction (like /tʃ/ in "chip").
What is an Approximant?
An approximant is a consonant produced with "open approximation." The articulators approach each other but do not get close enough to create any friction, making them sound very similar to vowels (e.g., /w/, /j/, /l/, /r/).
