Title: Re: temporal resolution

Hi Dave:

Arai & Greenberg (1998) studied speech intelligibility in samples in which spectral slices had undergone temporal jitter of this general kind.  My recollection is that asynchronies up to (and sometimes exceeding) 200 ms could support 50%-correct word recognition.  "Correct word recognition" is, of course, not the same thing as "perceptual equivalence".  My point is only that the Arai & Greenberg article might be a good place to start looking for the evidence you need.  I hope that this helps.  All good wishes,

Dennis
