Please see here for generating test synthesis labels only.
Are you working with English-language data? Follow these instructions.
Are you working with Babel data? Follow these instructions. They assume you already have a baseline Clustergen voice trained for your language, so make sure that that's been done as well.
You should end up with a set of .utt files that correspond to your data.
DUMPFEATS = /path/to/your/festival/examples/dumpfeats
You should add on the end of that: -eval
Speech lab students: We want to point it to the version of Festival where we have our voices installed, and choose e.g. a Babel voice. So e.g. if you are making labels for Turkish, change this line to:
DUMPFEATS = /proj/tts/tools/babel_scripts/build/festival/examples/dumpfeats -eval "(voice_cmu_babel_turkish_cg)"
And if you want to use a different voice frontend, put that instead. To see which voices are available, run (voice.list) inside of Festival. If the voice you want to use is not there yet, you will have to add it, by copying the etc, festvox, and festival directories from your Clustergen frontend into /proj/tts/tools/babel_scripts/build/festival/lib/voices/language/yourvoicename. You may have to make the language directory, and you will definitely have to make the voicename directory.
The output .lab files should be under labels/full/
