Onomatopoeia /ɑ-nə-mɑ-tə-pi-ə/ refers to the quality of a word in which its pronunciation mimics the sound it serves to represent (e.g., meow, crash, zoom). Onomatopoeia is one way that transliterators attempt to convey Auditory Environmental Stimuli.
The phonemic nature of Cued Speech gives it an advantage over signed languages in its ability to convey onomatopeia.
