  2. Phonetics is the study of how speech sounds – both consonants and vowels, and other phonetic features such as stress and intonation – are produced and what their properties are.

  3. the sounds that are used in the world’s languages. Phonetics studies It aims to examine - each individual sound - its properties and differences from the other sounds.

  4. Phonetics Articulatory phonetics Auditory phonetics Acoustic phonetics Production of speech sounds Perception of speech sounds Transmission of speech sounds through the air

  5. Speech production Respiratory process Phonatory process Articulatory process

  6. Three airstream mechanisms Pulmonic airstream mechanism Glottalic airstream mechanism Velaric airstream mechanism

  7. The PULMONIC airstream mechanism involves the lungs, which force air through the vocal tract for speech in the same way as for breathing.

  8. The GLOTTALIC airstream mechanism involves the glottis, and a raising or lowering of the vocal folds to change the pressure in the vocal tract. The pharyngeal airstream mechanism

  9. TheVELARICairstream mechanism is produced by a closure between the VELUM and the BACK of the TONGUE. The oralairstream mechanism

  10. The directions of airstream Ingressive airstream Egressive airstream

  11. The state of the glottis

  12. The state of the glottis • Whisper • Breathy voiced • Creaky voiced Closed glottis Open glottis Glottis in vibration

  13. Phonetics features consonants Airstream mechanism Pulmonic airstream mechanism Sounds which are made with vocal folds vibration The state of the glottis voiced voiceless Sounds made without vocal folds vibration Place of articulation Manner of articulation

  14. The English Consonants There are 3 aspects of articulatory properties 2. Place of articulation 1. Voicing 3. Manner of articulation
