Thanks for all that fast answers !
The Murray (2006) paper seems quite interesting because it suggest that
some semantic information was extracted from spectrotemporal patterns
quite early.

Are you talking about this one ?

It seems that the semantic level (in a semantic tree) of the question
asked to the participant was never taken into account in hearing
studies. Am I wrong ? In vision studies, this factor (base category,
super-ordonate category...) seems to modulates the results depending
on the task used (lexical verification, rapide search...).

Ballas (1993) measured identification of environmental sounds that were
truncated to 700 ms. He found they were quite well identified, but he
did not measure the time course - rather he measured reaction time,
which varied quite a bit.

in the Identification of an Assortment of Brief Everyday Sounds."
J. Exp. Psych.: Hum. Percep. & Perf. 19 (1993): 250--26
In my environmental studies I have tried to edit sounds so
that they were the briefest possible duration and still easily
identifiable in pilot studies. I found quite a range of times needed -
some complex events, like a bowling ball rolling down a lane, or a tree
falling, have quite extended times courses (> 3 s) needed to provide
all the information necessary.
There was a study involving time course of identification of
environmental scenes that was presented at a conference. I am away
from the office until next week, but I can provide the link then.
