What is the difference between acoustic phonetics and articulatory phonetics?
Articulatory phonetics deal mainly with how speech is made and acoustic phonetics what happens to that speech i.e. producing sound waves. The main difference therefore is in the in the process of speech.
Sounds formed using both upper and lower lips. (pat, bat, and mat).
Sounds formed with the upper teeth and the lower lip. (fat and vat).
Made with the tongue tip behind the upper front teeth. (thin and bath)
Formed with the front part of the tongue on the alveolar ridge. (top, dip, sit, zoo, and nut)
Sounds produced with the tongue and the palate. (shout and child)
Sounds produced with the back of the tongue against the velum. (kid, kill, car, and cold)
Produced with the active use of the tongue and other parts of the mouth. (who and whose).
Sounds produced by some form of "stopping" of the air stream (very briefly) then letting it go abruptly.
When you combine a brief stopping of the air stream with an obstructed release which causes some friction
When the velum is lowered and the air stream is allowed to flow out through the nose to produce. (morning, knitting, and name).
Formed by letting the air stream flow around the sides of the tongue as the tip of the tongue makes contact with the middle of the alveolar ridge. (red)
Typically produced with the tongue in motion (or gliding) to or from the position of a vowel and are sometimes called semi-vowels. (wet, yes, and we).
