Document Summary
Human vocal apparatus can make air vibrate by: vibrating vocal chords in throat, letting air flow through mouth. Vocal chords and mouth are separate vibration instruments : similar to musical instruments creating air vibrations. Can make sound with vocal chords while mouth closed humming. Can make sound by letting air flow through mouth without making vocal chords vibrate whispering or pop in /p/ sound: all consonants are based on this model, allowing air flow through mouth without vocal cords vibrating. Make /ba/ by combining vocal chords and mouth. /ba/: vibration caused by mouth happens almost at the same time as vibration caused by vocal chords. Make /pa/ by combining vocal chords and mouth. /pa/: vibration caused by mouth (initial pop in /pa/) happens before vibration caused by vocal chords. Although having a pear for lunch is wildly different from having a bear for lunch, only difference between the two words is: relative timing of mouth vibration vs. vocal chord vibration.
