In my 1994 paper in the IEEE Trans. on Speech and Audio Processing
(Vol 2, #4, Oct, pp 567-576) I conclude that based on Fletcher's
AI experiments, partial phone features must be extracted independently.
For example, at the top of section VI I say:
"Somehow the early CNS forms independent error estimates of features
across frequency ...."

My question is, could we be talking about the same thing?
Could the "concurrent audiory streams in parallel" just be
the different articulation channels across frequency?
