1. speech organs are necessary for making speech sounds (articulation)
1.1. speech sounds are divided into vowels and consonants.
1.1.1. A VOWEL is a voiced sound produced in the mouth cavity with no obstruction to the air stream.
1.1.1.1. iː I ɪ E Æ ɑː ɒ ɔː ʊ U uː ʌ ɜː ə eɪ əʊ aɪ ɔɪ aʊ ɪə eə ʊə
1.1.2. A CONSONANT is a sound produced with an obstruction to the air stream.
1.1.2.1. bilabial labiodental dental alveolar postalveolar palatal velar glottal
2. Passive: • tongue (movable) •the upper jaw (immovable) •the alveoli (immovable) •the hard palate (immovable) •the teeth (immovable)
2.1. The alveoli helps us to make different sounds, known as alveolar sounds
2.2. Hard palate plays a role as it separates the oral cavity from the nasal cavity,also aiding swallowing and speaking.
2.3. Teeth are responsible for creating sounds mainly the labio dental and lingua dental.
3. Actives: • the vocal chords; •the tongue; •the soft palate with the uvula; •the lips; •the lower jaw.
3.1. organs of speech which take an active part in the production of speech sounds are called active.
3.1.1. Lips creating mainly bilabial (/p/b/m/w) and Labio dental (/f/v/)
3.1.2. The tongue body touches the soft palate in order to make the sounds /k/, /g/, and /ŋ/.
3.1.3. the from portion of the vocal cords vibrate, producing a sound.
3.1.4. Jaw position is affect vowel height and plays role in manner of articulation
3.1.5. Tongue divided into tip,Blade,front, back,root and plays important part in almost every speech sound production
