The document discusses different types of speech sounds: 1. Voiced sounds involve vibration of the vocal cords, while voiceless sounds involve little vibration of the vocal cords. The difference can be felt by placing fingers on the mouth or ears. 2. Speech sounds are classified based on their manner of articulation, including stops/plosives, fricatives, affricates, nasals, laterals, vibrants, and semi-vowels. Each category is defined by how the air flow is obstructed in the mouth. 3. Examples are given for common consonant sounds in English to demonstrate each manner of articulation, such as [p] and [b] for stops, [s] and [

2.  VOICED SOUNDS
 The vocal cords is vibrate
 VOICELESS SOUNDS
 The vocal cords is not vibrate
 Actually in speed they always vibrate, but
here the vibration is very little

3.  These are two easy ways to feel or discover
the vibration of the vocal cords :
1. Put two or three fingers on your mouth and
say [s]; you will feel little or no vibration.
Keep your fingers in the same place and say
[z]; you will feel much more vibration
2. Cover your ears with the palms of your
hands and say [s]; you will feel and hear little
or no vibration. Now keep the palms of your
hands on your ears and say [z]; you will feel
and hear much more vibration

4.  STOPS OR PLOSIVES
 FRICATIVES OR SIBILANTS
 AFFRICATES
 NASALS
 LATERALS
 VIBRANTS
 SEMI-VOWELS

5.  STOPS OR PLOSIVES
 The word stop refers to the stopping of the
air
 The word plosive refers to the release of the
air
 These are sounds which are produced by
stopping the air somewhere in the mouth and
then releasing it
 [p] : voiceless ; [b] : voiced

6.  FRICATIVES OR SIBILANTS
 These are sounds which are produced by
having the air rub against some surface in the
mouth, causing friction
 [s] : voiceless ; [z] : voiced

7.  AFFRICATES
 These are sounds which are made up of two
parts : a stop and a fricative
 [tʃ] : voiceless ; [ʤ] : voiced

8.  NASALS
 These are sounds which are produced with
the air going through the nose or nasal cavity
 [m] : voiced ; [n] : voiced

9.  LATERALS
 These are sounds which are produced by
having the air go out of the mouth from both
side of the tongue
 [l] : voiced

10.  VIBRANTS
 These are sounds which are produced by
having the tongue vibrate in the mouth
 [r] : voiced

11.  SEMI-VOWELS
 These are sounds which are considered half
consonants and half vowels
 They are like consonants in their structural
behaviour; and they are like vowels in their
quality
 [w] : voiced ; [j] : voiced

12.  What is voiceless sounds? What is voiced
sounds?
 How is the way to different the sound is
voiceless or voiced?
 Close your note book
 Explain the manner of articulation
 Give the example briefly
