Within an uniform acoustic tube, regions having specific acoustic properties were defined [1, 2] and were at the origin of the Distinctive Region Model (DRM). Such a model has its own intrinsic phonology to produce distinctive sounds. In fact, the regions correspond to the main consonant places of articulation. Such results encourage to study the main predictions of the model: Theoretically, F2 can be used to separate /b/ from /d, g/, on the one hand, and F3 can be used to separate /d/ from /g/, on the other hand. This hypothesis was studied with perception tests. The role of the neutral pattern "schwa" (/@/), which corresponds to the uniform tube, as reference in the process of consonant perception is discussed.
