The Organs Of Speech And Their Functions Lesson 1: Everything You Need To Know | Speech Production
Understanding the Organs of Speech
Introduction to Organs of Speech
- Esther introduces the topic, focusing on the organs involved in speech production and their significance in articulating English sounds.
- The organs of speech, also known as articulators, are defined as parts of the human body that contribute to producing speech sounds.
Key Organs Involved in Speech Production
- A list of key organs includes: lips, teeth, tongue, nose, alveolar ridge, hard palate, soft palate (velum), uvula, esophagus, glottis, epiglottis, pharynx, larynx, vocal cords.
- The oral cavity and nasal cavities play crucial roles in sound production through mouth and nose respectively.
Role of Lips in Sound Production
- The lips consist of an upper lip and a lower lip; they can form various shapes (rounded, neutral or spread).
- Consonants produced with both lips are termed bilabial sounds (e.g., "pan," "ban").
- When airflow is obstructed by tightly pressed lips but released through the nose instead of the mouth, it produces bilabial nasal sounds (e.g., "man").
Functionality of Teeth in Articulation
- Teeth are categorized into upper and lower sets; they assist in forming dental sounds when the tongue is placed between them (e.g., "thin," "sin").
- Labiodental sounds occur when the lower lip contacts the upper teeth (e.g., "fan").
Importance and Structure of the Tongue
- The tongue is highlighted as a highly flexible organ essential for producing a wide range of speech sounds.
- It consists of four parts: tip, blade (edges), front part, and back part; each section contributes differently to sound articulation.
Alveolar Ridge's Contribution to Sounds
- The alveolar ridge is located just behind the upper front teeth; it plays a role in producing alveolar sounds when contacted by the tongue's tip (e.g., "ten," "sip").
- Sounds articulated at this location include various consonants where precise tongue placement against this ridge is critical.
