Frame T: Today, We shall be looking at the topic manner of articulation of English consonant sounds Focus T: Now, Let us stand up and move to the language laboratory for our drills (focus) S: (the students filed out of the class) Note that frame always precedes focus. A frame indicates the boundary in a lesson, while a focus starts off on what the speakers is about to dob Repetition T: Please note that the most important articulator in the production of speech sound is the tongue.

62 Illustrate T: We have just talked about manner of articulation. This helps us to describe the sound produced. In addition to this, we also want to look at another way we can describe sounds and that is the place of articulation or the point of articulation. This refers to those places in our vocal cavity where our articulators contact before sounds are produced. (Ill) Bola, stand up and tell me what I have just said. I noticed you were busy discussing with your friend. S: (Bola stood up and could not talk) T: You see what I keep telling you While I was busy explaining, she was talking. Expatiate T: I earlier said some sounds are produced with a plosion and they are called plosive sound. What then is a plosion? A plosion is a forceful sound. It comes outwith some force, because there is an obstruction prior to its production.(exp) Additive T: To describe any consonant, your have two ways the place of articulation and the manner of articulation S: In addition to this, we can also describe a consonant using voicing, which is the vibration or non-vibration of the vocal cord.(add)
