Document Summary
Phonetics- the scientific study of the inventory and structure of the sounds of human language; sounds used in speech. Articulatory- what we do to make the sounds (mouth, tongue, etc) Acoustic- physical properties of the sound waves themselves. Auditory- perception of speech sounds (brain, ears, nerves, etc) Muscles and ligaments that move the structure and effects the folds and opening as air passes through. Glottis- the opening/hole which air passes through. Different shapes will create different types of sounds. States of the glottis- changing gives different sounds. Voiceless- muscles have pulled vocal folds far apart, large hole/glottis; folds do not vibrate. Ie: f (fall), s (sound) and th (think) sounds. Voiced- push vocal folds close together (not closed), vibrating as air is pushed over/through them. Whispering- articulators are the same but change glottis to whisper state . Press vocal chords together so they do not vibrate.
