This repository provides word / phone alignment labels for LibriTTS Corpus.
The label files are created by Montreal-Forced-Aligner with provided pretrained model.
I assume that the labels are used to remove silence parts for E2E-TTS model training. So I did not carefully check the correctness of the boundaries of each phone and word, and oovs.
$ git clone https://github.com/kan-bayashi/LibriTTSCorpusLabel.git
$ cd LibriTTSCorpusLabel
$ cat textgrid.tar.gz-* > textgrid.tar.gz
$ cat lab.tar.gz-* > lab.tar.gz
$ tar xzvf textgrid.tar.gz
$ tar xzvf lab.tar.gzDue to the alignment failures, some labels are missing (1,255 files, around 0.4 %).
Please check missing_files.txt
This repository provides two types of alignments files:
.labformat separated with "\t",.TextGridformat, which the raw outputs of MFA.
.lab files are prepared for phone and word while .TextGrid includes both in a single file.
