+Run a bunch of words through the speech synthesizer
+and collect the results.
+Typical usage:
+ ./synth.pl [options] sport.vlist sport.vce sport.wav
+
+ Options include:
+ -skip # skip a line from the .vlist file;
+ -one # take only the first word from each line
+
+Note: -skip -one is useful if the .vlist file is actually in .vce format.
+
+Other usages:
+ ./synth.pl -dump foo.wav # dump headers 'foo.wav'
+ ./synth.pl -help # print this message
+
+where sport.vlist is a file containing a list of words, we use the
+first word on each line and ignore anything else on that line
+(which means a .vce file is acceptable as input, using -skip -one).
+
+Note that "atis-lex.pl" and "list-airports.pl" are useful for
+creating the .vlist file.
+
+Note that you may also need to:
+ cpan Audio::Wav
+ apt-get install festival mbrola sox festlex-oald
+ cd \$tars
+ wget http://tcts.fpms.ac.be/synthesis/mbrola/dba/en1/en1-980910.zip
