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/voices/english
|
|
mkdir en1_mbrola
