Welcome to the monastery.

For posting, use <code>code tags</code> around your code.

Useless use of cat: Put the filename after all other perl arguments, such as: 

perl -ne "blah" filename

You probably meant $3 instead of the duplicate $2.

.* is greedy, and will tend to eat too much. Given your input example, you might use \S+ to only capture non-whitespace, and .*? to be non-greedy elsewhere. Or, perhaps constrain your regex more with /Turn.*?speaker=(\S+)\s+startTime=(\S+)\s+endTime=(\S+)/

On Windoze/DOS, quoting is an issue, but you don't seem to have a problem so far. I prefer to use qq// and q// for quoting in perl oneliners. For example: 

perl -ne "print qq/$1 $2 $3\n/ if (/Turn.*?speaker=(\S+)\s+startTime=(
+\S+)\s+endTime=(\S+)/)" input_file > toto.xxx

To check the compile without running, add -c as a perl option: 

perl -c -ne "print qq/$1 $2 $3\n/ if (/Turn.*?speaker=(\S+)\s+startTim
+e=(\S+)\s+endTime=(\S+)/)"
-e syntax OK
