Building a Unit Selection Cluster Voice

(from here http://festvox.org/festvox/x3082.html)

1. mkdir uw_uw_rdt

cd uw_uw_rdt

1. uniphone setup:

    $FESTVOXDIR/src/unitsel/setup_clunits uw us rdt uniphone

2. generate prompts and prompt files:

   festival -b festvox/build_clunits.scm '(build_prompts_waves "etc/uniphone.data")'

3. record sound, using audacity. save as 16k, 16bit mono.
4. make labels:

   ./bin/make_labs prompt-wav/*.wav

5. build utterance structure:

   festival -b festvox/build_clunits.scm '(build_utts "etc/uniphone.data")'

6. do pitch marking:

   ./bin/make_pm_wave etc/uniphone.data

7. find Mel Frequency Cepstral Coefficients:

   ./bin/make_mcep etc/uniphone.data

8. 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.")
