Building a Unit Selection Cluster Voice
(from here http://festvox.org/festvox/x3082.html)
mkdir uw_uw_rdt
- uniphone setup:
$FESTVOXDIR/src/unitsel/setup_clunits uw us rdt uniphone
- generate prompts and prompt files:
festival -b festvox/build_clunits.scm '(build_prompts_waves "etc/uniphone.data")'
- record sound, using audacity. save as 16k, 16bit mono.
- make labels:
./bin/make_labs prompt-wav/*.wav
- build utterance structure:
festival -b festvox/build_clunits.scm '(build_utts "etc/uniphone.data")'
- do pitch marking:
./bin/make_pm_wave etc/uniphone.data
- find Mel Frequency Cepstral Coefficients:
./bin/make_mcep etc/uniphone.data
- build cluster unit selection synth:
festival -b festvox/build_clunits.scm '(build_clunits "etc/uniphone.data")'
Using a Unit Selection Cluster Voice Synth
- from uw_us_rdt directory:
festival festvox/uw_us_rdt_clunits.scm
- in Scheme:
(voice_uw_us_rdt_clunits)
(SayText "this is a little test.")
Building a CLUSTERGEN Statistical Parametric Synthesizer
adapted from http://festvox.org/festvox/c3170.html#AEN3172
mkdir uw_us_rdt_arctic
uw_us_rdt_arctic $FESTVOXDIR/src/clustergen/setup_cg uw us rdt_arctic
- copy text into
etc/txt.done.data
. use some of the lines from here http://www.festvox.org/cmu_arctic/cmuarctic.data - copy audio files into
wav/
- use
bin/get_wavs
to copy files to power normalize and convert to proper format.
Building a Unit Selection Cluster Voice from TIMIT data
(from here http://festvox.org/festvox/x3082.html)
mkdir uw_uw_rdt_timit
- timit setup:
$FESTVOXDIR/src/unitsel/setup_clunits uw us rdt timit
- generate prompts and prompt files:
festival -b festvox/build_clunits.scm '(build_prompts_waves "etc/timit.data")'
- record sound, using audacity. save as 16k, 16bit mono.
- make labels:
./bin/make_labs prompt-wav/*.wav
- build utterance structure:
festival -b festvox/build_clunits.scm '(build_utts "etc/timit.data")'
- do pitch marking:
./bin/make_pm_wave etc/timit.data
- find Mel Frequency Cepstral Coefficients:
./bin/make_mcep etc/timit.data
- build cluster unit selection synth:
festival -b festvox/build_clunits.scm '(build_clunits "etc/timit.data")'

Using Voices
using meghan voice
To run the server:
- open terminal:
cd /Users/murmur/Desktop/meghan festival_server -c meghans_special_sauce.scm
- To kill the server:
Control-C
- To run the client:
open a 2nd terminal window: cd /Users/murmur/Desktop/meghan festival_client myfile.txt --ttw --output client_test.wav
- Other stuff (python):
import os os.popen("/Applications/festival_2.1/festival/src/main/festival_client /Users/murmur/Desktop/meghan/myfile.txt --ttw --output /Users/murmur/Desktop/meghan/client_test78.wav")
Using new Voices
Modify new voice so festival knows it's there
- append to uw_us_rdt_clunits.scm in uw_us_rdt_clunits/festvox:
(proclaim_voice
'uw_us_rdt_clunits '((language english) (gender male) (dialect american) (description "This is Robert Twomey trained on CLUNITS, TIMIT databse.")))
(provide 'uw_us_rdt_clunits)
=Install voice to festival directory
- http://roberttwomey.com/downloads/uw_us_rdt_clunits.tar.gz
- unzip file from festival root directory, it should install to the correct directory
- copy your newly trained voice to
festival/lib/voices/english/
- the name of your new voice directory (ex:
uw_us_rdt_clunits/
) needs to match the voice file (ex:uw_us_rdt_clunits/festvox/uw_us_rdt_clunits.scm
)
Configure festival to use your voice by default
- to set your voice as default, add the following to
festival/etc/siteinit.scm
:
(autoload voice_uw_us_rdt_clunits "/Users/rtwomey/code/tts/festival/lib/voices/english/uw_us_rdt_clunits/festvox/uw_us_rdt_clunits" "American English male uw_us_rdt_clunits") (set! voice_default 'voice_uw_us_rdt_clunits) (voice_uw_us_rdt_clunits) (lex.add.entry '("<break>" n (((pau pau) 0))))
- the
lex.add.entry
line makes a new word in the lexicon<break>
that adds a pause. - change directory
cd
to the folder containing yourfestvox
files (trained model) - run
festival_server
and it will load your new voice by default - http://www.cstr.ed.ac.uk/projects/festival/manual/festival_24.html
