I was trying to see how difficult putting speech,music or scenes together becomes based on segment duration and number. But, unfortunately it never got to a formal experiment. One curious effect I remember is that when you 'scramble' a speech utterance of a single talker into very short segments (I want to say 50 -100 ms long, but I don't remember precisely now), you actually hear more than one talker, which is not all that surprising I thought given the discontinuities introduced during scrambling. If you are interested, I can look if I still have the code.

That means for example: first step, segmentation of a 4 secs phrase in 10 segments of 400ms: second step, rearragement in a random order. An advanced implementation would be to have the opportunity to define any possible time range (i.e 50-400ms), at which the script rearranges the file randomly. Thanks for any ideas, Mathias -- ************************************************** Mathias Oechslin Ph.D student Department of Neuropsychology Institute for Psychology Binzmühlestrasse 14/25 University of Zürich CH-8050 Zürich Switzerland http://www.psychologie.unizh.ch/neuropsy/ m.oechslin@xxxxxxxx phone: +41 44 635 74 07 **************************************************
