Abstract

The orderly output constraint (OOC) is extraneous. Talkers “speak in lines” in its absence. Further, there is no perceptual motivation for an OOC; perceivers ignore the linearity between F2 at consonant-vowel onset and F2 in the vowel. In any case, the analogy with bat and barn owl localization systems underlying the theory is extreme, Sussman et al.'s comments to the contrary notwithstanding.
