FastSpeech2 with the VCTK
This example contains code used to train a Fastspeech2 model with VCTK.
Dataset
Download and Extract the dataset
Download VCTK-0.92 from the official website.
Get MFA Result and Extract
We use MFA to get durations for fastspeech2. You can download from here vctk_alignment.tar.gz, or train your MFA model reference to mfa example of our repo. ps: we remove three speakers in VCTK-0.92 (see reorganize_vctk.py):
p315
, because of no text for it.p280
andp362
, because no *_mic2.flac (which is better than *_mic1.flac) for them.
Get Started
Assume the path to the dataset is ~/datasets/VCTK-Corpus-0.92
.
Assume the path to the MFA result of VCTK is ./vctk_alignment
.
Run the command below to
- source path.
- preprocess the dataset.
- train the model.
- synthesize wavs.
- synthesize waveform from
metadata.jsonl
. - synthesize waveform from text file.
- synthesize waveform from
./run.sh
You can choose a range of stages you want to run, or set stage
equal to stop-stage
to use only one stage, for example, running the following command will only preprocess the dataset.
./run.sh --stage 0 --stop-stage 0
Data Preprocessing
./local/preprocess.sh ${conf_path}
When it is done. A dump
folder is created in the current directory. The structure of the dump folder is listed below.
dump
├── dev
│ ├── norm
│ └── raw
├── phone_id_map.txt
├── speaker_id_map.txt
├── test
│ ├── norm
│ └── raw
└── train
├── energy_stats.npy
├── norm
├── pitch_stats.npy
├── raw
└── speech_stats.npy
The dataset is split into 3 parts, namely train
, dev
, and test
, each of which contains a norm
and raw
subfolder. The raw folder contains speech、pitch and energy features of each utterance, while the norm folder contains normalized ones. The statistics used to normalize features are computed from the training set, which is located in dump/train/*_stats.npy
.
Also, there is a metadata.jsonl
in each subfolder. It is a table-like file that contains phones, text_lengths, speech_lengths, durations, the path of speech features, the path of pitch features, the path of energy features, speaker, and id of each utterance.
