DiffSinger with Opencpop
This example contains code used to train a DiffSinger model with Mandarin singing corpus.
Dataset
Download and Extract
Download Opencpop from it's Official Website and extract it to ~/datasets
. Then the dataset is in the directory ~/datasets/Opencpop
.
Get Started
Assume the path to the dataset is ~/datasets/Opencpop
.
Run the command below to
- source path.
- preprocess the dataset.
- train the model.
- synthesize wavs.
- synthesize waveform from
metadata.jsonl
. - (Supporting) synthesize waveform from a text file.
- synthesize waveform from
- (Supporting) inference using the static model.
./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
└── speech_stretchs.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
. speech_stretchs.npy
contains the minimum and maximum values of each dimension of the mel spectrum, which is used for linear stretching before training/inference of the diffusion module.
Note: Since the training effect of non-norm features is due to norm, the features saved under norm
are features that have not been normed.
Also, there is a metadata.jsonl
in each subfolder. It is a table-like file that contains utterance id, speaker id, phones, text_lengths, speech_lengths, phone durations, the path of speech features, the path of pitch features, the path of energy features, note, note durations, slur.
