Velar stops are phonetically characterized by two allophones—a palatal ‘‘g’’ when produced in front-vowel contexts and a velar ‘‘g’’ when produced in backvowel contexts. Acoustic characterizations of velar stops based on plotting the onset and offset frequencies of the second formant transition clearly reveal two acoustically separated allophonic groups. Using cross-linguistic acoustic data, it is shown that alveolar stops fall precisely within the acoustic void created by the velar allophones. A neural-based mapping hypothesis is put forth claiming that the bimodal distribution of velars is an instance of articulatory behavior acting in the service of auditory representation.
