3. Why use phonemic symbols? The alphabet which we use to write English has 26 letters but (British) English has 44 sounds. Inevitably, English spelling is not a reliable guide to pronunciation because Some letters have more than one sound Sometimes letters are not pronounced at all The same sound may be represented by different letters Sometimes syllables indicated by the spelling are not pronounced at all Questions: How do you pronounce gh in 'enough', 'through' and 'ghost'? (like f in fun, not pronounced, like g in got) How many syllables are there in 'chocolate'?

4. Phonemes Linguists classify the speech sounds used in a language into a number of abstract categories called phonemes. English, for example, has 44 phonemes, although the number varies according to the dialect of the speaker and the system of the classification. Phonemes are abstract categories which allow us to group together subsets of speech sounds. Even though no two speech sounds, or phones, are identical, all of the phones classified into one phoneme category are similar enough so that they convey the same meaning.

5. Description of the English consonants English consonants can be classified according to 1. the points of articulation 2. the manners of articulation 3. the state of the vocal cords

6. Points of articulation 1. bilabial (two lips) 2. labio-dental (top teeth/bottom lip) 3. dental (tongue tip/top teeth) 4. alveolar (tongue tip/tooth ridge) 5. post alveolar (tongue tip or mid/hard palate) 6. palatal (tongue mid/hard palate) 7. velar (tongue back/ soft palate) 8. glottal

7. Manners of articulation 1. Stops (or plosives) 2. Fricatives 3. Affricates 4. Nasals 5. Lateral 6. Approximants

12. English Consonants 1. Stops/Plosives - English has six bursts or explosive sounds produced by complete closure of the vocal tract followed by a rapid release of the closure - 'p', 't', 'k', 'b', 'd', 'g'. 2. Fricatives - English has nine fricatives - weak or strong friction noises produced when the articulators are close enough together to cause turbulence in the airflow. 3. Affricates - English has two affricates - plosives released with frication - "church" and "judge". 4. Nasals - English has three nasals in which the airflow is blocked completely at some point in the oral tract, but in which the lowering of the velum allows a weak flow of energy to pass through the nose. 5. Approximants - English has four approximants - the 'w' in "won", the 'l' in "like", the 'r' in "red", and the 'y' in "yes." In these phonemes, there is more constriction in the vocal tract than for the vowels, but less than the other consonant categories below.

21. Ex. 2Materials for reading aloud Americans eat breakfast and lunch quickly unless it is a social, business or family occasion. The evening meal is usually longer and a time for families to gather together. Rushing through daytime meals is part of the fast pace in America. Another reason for rushing through daytime meals is that many people eat in restaurants that are usually crowded with people waiting for a place so that they can be served and return to work at the proper time. So each one hurries to make room for the next person. As with busy people everywhere, there is a real difference between meals that are eaten in a hurry and those that can be enjoyed slowly with friends.
