Document Summary

By the end of this section, you should know: Can be understood up to a rate of 50 units/second normal speech is 12 units/second. We can compare our rapid perception of speech to non-speech sounds in which our perception is limited to 0. 67 units/second. A collection of ordered sounds to which meaning is attached: phoneme sound, vowel sound, high or low pitch. Produced by vibrating the vocal folds as air moves out of the lungs through the open mouth. If you produce any vowel, your mouth is fairly open and the sound we produce depends on the various positions of the articulators in your mouth. Sound produced depends on positions of structures of the vocal tract: tongue position is a critical part of producing vowel sounds, vowel sounds largely produced in conjunction with vocal chords moving in and out and the articulators. Produced by closing or constricting the vocal tract.
