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

cd /usr/share/festival

cd lib
ln -s ../voices ./
cd /usr/share
tar -xpzvf \$tars/festvox_en1.tar.gz
