Alternative reduplication achieves the semantic emphasis through asymmetrical coordination between the base and the reduplicant based on the maximum difference of F1 in vowels, or syllable duration in consonaants. These asymmentrical distribution of acoustical cues causes the perceptual enhancement in the alternative reduplicaiton. On the other hand . C-C symmetrical reduplication gains the goal through overgeneralization, in which the first symmetrical reduplication gains the goal through overgeneralization, in which the phoneme in the first syllable of the reduplicant copies back to the first syllable of the base. Generally , alternative reduplication of '⌀-C symmetry' formation gets the emphatic formation using the perceptual prominence to C-C symmetry formation. This overgeneralization is controlled by phonological and analogical conditions. While the vowel alternative reduplication changes into C-C symmetrical form, both consonantal alternatives with deletion and syllable alternative reduplication cannot be changed into C-C symmetrical forms. The similar reason could be applied to the consonantal alternatives with deletion and syllable alternative reduplication cannot be changed into C-C symmetrical forms. The similar reason could be applied to the consonantal alternatives with addition, in which 'p' and 't' occurring in the onset of the base form could be prohibited to change into symmetrical reduplication. In summary, the pure reduplication which repeats the base improves the semantic emphatic through non-morphological motivation : perceptual and production effects.
