The document discusses five topics related to speech and oral presentation: voice projection, breathing techniques, articulation, sounds of American English, and phonetic symbols. It covers how to project the voice appropriately for different situations, the three main types of breathing for speaking, how articulation allows breath to be shaped into speech sounds, the production of vowels and diphthongs, and two methods for representing sounds in English through spelling or phonetic transcription.

2. VOICE and PROJECTION
 Voice Projection
-Projection is the carrying over of the voice.
The voice amplification ought to be appropriate to the
message, audience, and location.
The kind of projection used for oration is different
from that for reading love poems.

3. BREATHING
 Types of Breathing
 I. Diaphragmatic Breathing. -This is recommended by most
trained voice and speech instructor.
 II. Clavicular Breathing. -The speaker raises the shoulder
and collarbones while inhaling.
 III. Thoracic Breathing. -The sternum (breastbone) is
elevated during inhalation and pulls in the lower ribs during
the exhalation.

4. ORAL COMMUNICATOIN
 Articulation - is the procedure that
allows the outgoing breath to be
widened, narrowed, or closed off and
categorized into various recognizable
speech sounds.

5. SOUND OF AMERICAN
ENGLISH
 Vowel sounds and diphthongs. - All
vowels are voiced sounds. They are
produced without any interruption and
restriction of the steams of breath.

6. THE PHONETIC SYMBOLS
 I. The International Phonetic Alphabet
- There are two ways of representing
the sounds of English – through
spelling (orthographic representation)
or through phonetic transcriptions.
