## Features
|
|
|
🌍 **Chinese** supported mandarin and tested with multiple datasets: aidatatang_200zh, magicdata, aishell3, data_aishell, and etc.
|
|
|
|
|
|
🤩 **PyTorch** worked for pytorch, tested in version of 1.9.0(latest in August 2021), with GPU Tesla T4 and GTX 2060
|
|
|
|
|
|
🌍 **Windows + Linux** run in both Windows OS and linux OS (even in M1 MACOS)
|
|
|
|
|
|
🤩 **Easy & Awesome** effect with only newly-trained synthesizer, by reusing the pretrained encoder/vocoder
|
|
|
|
|
|
🌍 **Webserver Ready** to serve your result with remote calling

|
|
|
|
## Quick Start
|
|
|
|
|
|
### 1. Install Requirements
|
|
|
> Follow the original repo to test if you got all environment ready.
|
|
|
**Python 3.7 or higher ** is needed to run the toolbox.
|
|
|
|
|
|
* Install [PyTorch](https://pytorch.org/get-started/locally/).
|
|
|
> If you get an `ERROR: Could not find a version that satisfies the requirement torch==1.9.0+cu102 (from versions: 0.1.2, 0.1.2.post1, 0.1.2.post2 )` This error is probably due to a low version of python, try using 3.9 and it will install successfully
|
|
|
* Install [ffmpeg](https://ffmpeg.org/download.html#get-packages).
|
|
|
* Run `pip install -r requirements.txt` to install the remaining necessary packages.
|
|
|
* Install webrtcvad `pip install webrtcvad-wheels`(If you need)
|
|
|
> Note that we are using the pretrained encoder/vocoder but synthesizer since the original model is incompatible with the Chinese symbols. It means the demo_cli is not working at this moment.
|
|
|
### 2. Prepare your models
|
|
|
You can either train your models or use existing ones:
|
|
|
|
|
|
#### 2.1 Train encoder with your dataset (Optional)
|
|
|
|
|
|
* Preprocess with the audios and the mel spectrograms:
|
|
|
`python encoder_preprocess.py <datasets_root>` Allowing parameter `--dataset {dataset}` to support the datasets you want to preprocess. Only the train set of these datasets will be used. Possible names: librispeech_other, voxceleb1, voxceleb2. Use comma to sperate multiple datasets.
|
|
|
|
|
|
* Train the encoder: `python encoder_train.py my_run <datasets_root>/SV2TTS/encoder`
|
|
|
> For training, the encoder uses visdom. You can disable it with `--no_visdom`, but it's nice to have. Run "visdom" in a separate CLI/process to start your visdom server.
|
|
|
|
|
|
#### 2.2 Train synthesizer with your dataset
|
|
|
* Download dataset and unzip: make sure you can access all .wav in folder
|
|
|
* Preprocess with the audios and the mel spectrograms:
|
|
|
`python pre.py <datasets_root>`
|
|
|
Allowing parameter `--dataset {dataset}` to support aidatatang_200zh, magicdata, aishell3, data_aishell, etc.If this parameter is not passed, the default dataset will be aidatatang_200zh.
|
|
|
|
|
|
* Train the synthesizer:
|
|
|
`python synthesizer_train.py mandarin <datasets_root>/SV2TTS/synthesizer`
|
|
|
|
|
|
* Go to next step when you see attention line show and loss meet your need in training folder *synthesizer/saved_models/*.
|
|
|
|
|
|
#### 2.3 Use pretrained model of synthesizer
|
|
|
> Thanks to the community, some models will be shared:

|
|
|
|
|
#### 2.4 Train vocoder (Optional)
|
|
|
> note: vocoder has little difference in effect, so you may not need to train a new one.
|
|
|
* Preprocess the data:
|
|
|
`python vocoder_preprocess.py <datasets_root> -m <synthesizer_model_path>`
|
|
|
> `<datasets_root>` replace with your dataset root，`<synthesizer_model_path>`replace with directory of your best trained models of sythensizer, e.g. *sythensizer\saved_mode\xxx*
|
|
|
|
|
|
* Train the wavernn vocoder:
|
|
|
`python vocoder_train.py mandarin <datasets_root>`
|
|
|
|
|
|
* Train the hifigan vocoder
|
|
|
`python vocoder_train.py mandarin <datasets_root> hifigan`
|
|
|
|
|
|
### 3. Launch
|
|
|
#### 3.1 Using the web server
|
|
|
You can then try to run:`python web.py` and open it in browser, default as `http://localhost:8080`
|
|
|
|
|
|
#### 3.2 Using the Toolbox
|
|
|
You can then try the toolbox:
|
|
|
`python demo_toolbox.py -d <datasets_root>`
|
|
|
|
|
|
#### 3.3 Using the command line
|
|
|
You can then try the command:
|
|
|
`python gen_voice.py <text_file.txt> your_wav_file.wav`
|
|
|
you may need to install cn2an by "pip install cn2an" for better digital number result.

|
|
> After unzip aidatatang_200zh, you need to unzip all the files under `aidatatang_200zh\corpus\train`
|
|
|
|
|
|
#### 2.What is`<datasets_root>`?
|
|
|
If the dataset path is `D:\data\aidatatang_200zh`,then `<datasets_root>` is`D:\data`
|
|
|
|
|
|
#### 3.Not enough VRAM
|
|
|
Train the synthesizer：adjust the batch_size in `synthesizer/hparams.py`
|
|
|
```
|
|
|
//Before
|
|
|
tts_schedule = [(2, 1e-3, 20_000, 12), # Progressive training schedule
|
|
|
(2, 5e-4, 40_000, 12), # (r, lr, step, batch_size)
|
|
|
(2, 2e-4, 80_000, 12), #
|
|
|
(2, 1e-4, 160_000, 12), # r = reduction factor (# of mel frames
|
|
|
(2, 3e-5, 320_000, 12), # synthesized for each decoder iteration)
|
|
|
(2, 1e-5, 640_000, 12)], # lr = learning rate
|
|
|
//After
|
|
|
tts_schedule = [(2, 1e-3, 20_000, 8), # Progressive training schedule
|
|
|
(2, 5e-4, 40_000, 8), # (r, lr, step, batch_size)
|
|
|
(2, 2e-4, 80_000, 8), #
|
|
|
(2, 1e-4, 160_000, 8), # r = reduction factor (# of mel frames
|
|
|
(2, 3e-5, 320_000, 8), # synthesized for each decoder iteration)
|
|
|
(2, 1e-5, 640_000, 8)], # lr = learning rate
|
|
|
```
|
|
|
|
|
|
Train Vocoder-Preprocess the data：adjust the batch_size in `synthesizer/hparams.py`
|
|
|
```
|
|
|
//Before
|
|
|
### Data Preprocessing
|
|
|
max_mel_frames = 900,
|
|
|
rescale = True,
|
|
|
rescaling_max = 0.9,
|
|
|
synthesis_batch_size = 16, # For vocoder preprocessing and inference.
|
|
|
//After
|
|
|
### Data Preprocessing
|
|
|
max_mel_frames = 900,
|
|
|
rescale = True,
|
|
|
rescaling_max = 0.9,
|
|
|
synthesis_batch_size = 8, # For vocoder preprocessing and inference.
|
|
|
```
|
|
|
|
|
|
Train Vocoder-Train the vocoder：adjust the batch_size in `vocoder/wavernn/hparams.py`
|
|
|
```
|
|
|
//Before
|
|
|
# Training
|
|
|
voc_batch_size = 100
|
|
|
voc_lr = 1e-4
|
|
|
voc_gen_at_checkpoint = 5
|
|
|
voc_pad = 2
|
|
|
|
|
|
//After
|
|
|
# Training
|
|
|
voc_batch_size = 6
|
|
|
voc_lr = 1e-4
|
|
|
voc_gen_at_checkpoint = 5
|
|
|
voc_pad =2
|
|
|
```
|
|
|
|
|
|
#### 4.If it happens `RuntimeError: Error(s) in loading state_dict for Tacotron: size mismatch for encoder.embedding.weight: copying a param with shape torch.Size([70, 512]) from checkpoint, the shape in current model is torch.Size([75, 512]).`
|
|
|
Please refer to issue [#37](https://github.com/babysor/MockingBird/issues/37)
|
|
|
|
|
|
#### 5. How to improve CPU and GPU occupancy rate?
|
|
|
Adjust the batch_size as appropriate to improve
|
|
|
|
|
|
|
|
|
#### 6. What if it happens `the page file is too small to complete the operation`
|
|
|
Please refer to this [video](https://www.youtube.com/watch?v=Oh6dga-Oy10&ab_channel=CodeProf) and change the virtual memory to 100G (102400), for example : When the file is placed in the D disk, the virtual memory of the D disk is changed.
|
|
|
|
|
|
#### 7. When should I stop during training?
|
|
|
FYI, my attention came after 18k steps and loss became lower than 0.4 after 50k steps.
