The Eight Parts of Human Speech Organs & Their Definitions
Lips, Teeth, Tongue
Lips form different shapes, such as an oval, and movements in order to make different sounds. Sounds can be formed by using the teeth to shape the lips, in combination with the tongue, or to block air from escaping the mouth. The tongue moves throughout the mouth and with many of the other organs, as well as making shapes like the lips, in order to formulate speech.
The uvula is used to make guttural sounds. It helps to make nasal consonants by stopping air from moving through the nose.
The glottis is used in controlling the vibration made by the vocal chords, in order to make different sounds.
To make different sounds, known as alveolar sounds, the tongue touches the ridges found on this organ.
Like the alveolar ridge, the tongue touches and taps the palate when articulating speech.
Velum (Soft Palate)
The movable velum can retract and elevate in order to separate the mouth from the nasal cavity, helping to make speech less nasally. When the tongue hits the velum, it also makes a special sound called the velar consonant.
Elements of Speech
1. Articulation of words:
Give ears to the patient’s speech. Is he speaking the words clearly? Observe if he is having a nasal tone and also see how clear and distinct the words are. Can you clearly make out words from his speech?
All these do come under articulation of speech.
A common disease associated with articulation of speech is Dysarthria. Dysarthria is nothing but defective articulation.
Observe how loud the patient speaks. A depressive patient may remain silent or he may speak but would be hardly audible. This is characteristics of many psychotic disorders as well.
Fluency is a combination of the flow of speech, the rate at which its spoken, how the words are...
