Speech perception system of perceptual phonetics

The perception of speech signal is to complete a series of speech through a continuous perception system from hearing to nerve. Due to the limitation of experimental means, some theories are still in the hypothetical stage, and many facts have to be obtained indirectly through phonetic experiments. The important mechanism of perception and the function of nervous system are still being explored. The stimulation of speech sound waves is transformed into auditory nerve impulses in the auditory receptors of cochlea, and then transmitted to the central nervous system of the brain, which sorts, classifies and decodes them.
