Document Summary
All the theory s discussed are based on how do we perceive individual phonemes. Vowels: have nice pattern; predictable 1:1 nature. We can use categorical perception assume that is similar in there sound they are the same thing (differentiation of a phoneme is still the same phoneme. Motor theory s (stevens and halle 1964) analysis by synthesis. Speech is not perceived just as a auditory phenomenon, but also a motor phenomenon. You perceive speech, not by taking in frequency, but by asking yourself how would i have made those sounds. Filtering the sounds through your articular apparatus. So not just the sound, the motor movements to make this sound. When you produce a d sound, you produce it the same way each time (d sound in duh, dad etc. ) The articulatory nature of the sound does not change, no matter what is put behind the consonant. Is there evidence: this launched people in to different experiments.
