Dear list, I wonder how human performance in phoneme recognition depends on the stimulus length. I'm thinking of an experiment something like "name the last phoneme you hear", and the length of the sound excerpt played would vary between, say, 10ms and a couple of seconds (with the end always fit to the end of a phoneme). Since I'm interested in the importancy of long-term adaptation, nonsense worlds should be used to exclude linguistic help. Does anyone know about such or similar experiments? P.S.: My special interest is whether information earlier than the "magic" 250ms is important, and how much (I would like to draw some conclusions for automatic speech recognition).
