+# VITS with AISHELL-3
+This example contains code used to train a [VITS](https://arxiv.org/abs/2106.06103) model with [AISHELL-3](http://www.aishelltech.com/aishell_3). The trained model can be used in Voice Cloning Task, We refer to the model structure of [Transfer Learning from Speaker Verification to Multispeaker Text-To-Speech Synthesis](https://arxiv.org/pdf/1806.04558.pdf). The general steps are as follows:
+1. Speaker Encoder: We use Speaker Verification to train a speaker encoder. Datasets used in this task are different from those used in `VITS` because the transcriptions are not needed, we use more datasets, refer to [ge2e](https://github.com/PaddlePaddle/PaddleSpeech/tree/develop/examples/other/ge2e).
+2. Synthesizer and Vocoder: We use the trained speaker encoder to generate speaker embedding for each sentence in AISHELL-3. This embedding is an extra input of `VITS` which will be concated with encoder outputs. The vocoder is part of `VITS` due to its special structure.
+
+## Dataset
+### Download and Extract
+Download AISHELL-3 from it's [Official Website](http://www.aishelltech.com/aishell_3) and extract it to `~/datasets`. Then the dataset is in the directory `~/datasets/data_aishell3`.
+
+### Get MFA Result and Extract
+We use [MFA2.x](https://github.com/MontrealCorpusTools/Montreal-Forced-Aligner) to get phonemes for VITS, the durations of MFA are not needed here.
+You can download from here [aishell3_alignment_tone.tar.gz](https://paddlespeech.bj.bcebos.com/MFA/AISHELL-3/with_tone/aishell3_alignment_tone.tar.gz), or train your MFA model reference to [mfa example](https://github.com/PaddlePaddle/PaddleSpeech/tree/develop/examples/other/mfa) (use MFA1.x now) of our repo.
+
+## Pretrained GE2E Model
+We use pretrained GE2E model to generate speaker embedding for each sentence.
+
+Download pretrained GE2E model from here [ge2e_ckpt_0.3.zip](https://bj.bcebos.com/paddlespeech/Parakeet/released_models/ge2e/ge2e_ckpt_0.3.zip), and `unzip` it.
+
+## Get Started
+Assume the path to the dataset is `~/datasets/data_aishell3`.
+Assume the path to the MFA result of AISHELL-3 is `./aishell3_alignment_tone`.
+Assume the path to the pretrained ge2e model is `./ge2e_ckpt_0.3`.
+
+Run the command below to
+1. **source path**.
+2. preprocess the dataset.
+3. train the model.
+4. synthesize waveform from `metadata.jsonl`.
+5. start a voice cloning inference.
+
+```bash
+./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.
+```bash
+./run.sh --stage 0 --stop-stage 0
+```
+
+### Data Preprocessing
+```bash
+CUDA_VISIBLE_DEVICES=${gpus} ./local/preprocess.sh ${conf_path} ${ge2e_ckpt_path}
+```
+When it is done. A `dump` folder is created in the current directory. The structure of the dump folder is listed below.
+
+```text
+dump
+├── dev
+│ ├── norm
+│ └── raw
+├── embed
+│ ├── SSB0005
+│ ├── SSB0009
+│ ├── ...
+│ └── ...
+├── phone_id_map.txt
+├── speaker_id_map.txt
+├── test
+│ ├── norm
+│ └── raw
+└── train
+ ├── feats_stats.npy
+ ├── norm
+ └── raw
+```
+The `embed` contains the generated speaker embedding for each sentence in AISHELL-3, which has the same file structure with wav files and the format is `.npy`.
+
+The computing time of utterance embedding can be x hours.
+
+The dataset is split into 3 parts, namely `train`, `dev`, and` test`, each of which contains a `norm` and `raw` subfolder. The raw folder contains wave and linear spectrogram of each utterance, while the norm folder contains normalized ones. The statistics used to normalize features are computed from the training set, which is located in `dump/train/feats_stats.npy`.
+
+Also, there is a `metadata.jsonl` in each subfolder. It is a table-like file that contains phones, text_lengths, feats, feats_lengths, the path of linear spectrogram features, the path of raw waves, speaker, and the id of each utterance.
+
+The preprocessing step is very similar to that one of [vits](https://github.com/PaddlePaddle/PaddleSpeech/tree/develop/examples/aishell3/vits), but there is one more `ge2e/inference` step here.
+
+### Model Training
+```bash
+CUDA_VISIBLE_DEVICES=${gpus} ./local/train.sh ${conf_path} ${train_output_path}
+```
+The training step is very similar to that one of [vits](https://github.com/PaddlePaddle/PaddleSpeech/tree/develop/examples/aishell3/vits), but we should set `--voice-cloning=True` when calling `${BIN_DIR}/train.py`.
+
+### Synthesizing
+
+`./local/synthesize.sh` calls `${BIN_DIR}/synthesize.py`, which can synthesize waveform from `metadata.jsonl`.
+
+```bash
+CUDA_VISIBLE_DEVICES=${gpus} ./local/synthesize.sh ${conf_path} ${train_output_path} ${ckpt_name}
+```
+```text
+usage: synthesize.py [-h] [--config CONFIG] [--ckpt CKPT]
+ [--phones_dict PHONES_DICT] [--speaker_dict SPEAKER_DICT]
+ [--voice-cloning VOICE_CLONING] [--ngpu NGPU]
+ [--test_metadata TEST_METADATA] [--output_dir OUTPUT_DIR]
+
+Synthesize with VITS
+
+optional arguments:
+ -h, --help show this help message and exit
+ --config CONFIG Config of VITS.
+ --ckpt CKPT Checkpoint file of VITS.
+ --phones_dict PHONES_DICT
+ phone vocabulary file.
+ --speaker_dict SPEAKER_DICT
+ speaker id map file.
+ --voice-cloning VOICE_CLONING
+ whether training voice cloning model.
+ --ngpu NGPU if ngpu == 0, use cpu.
+ --test_metadata TEST_METADATA
+ test metadata.
+ --output_dir OUTPUT_DIR
+ output dir.
+```
+The synthesizing step is very similar to that one of [vits](https://github.com/PaddlePaddle/PaddleSpeech/tree/develop/examples/aishell3/vits), but we should set `--voice-cloning=True` when calling `${BIN_DIR}/../synthesize.py`.
+
+### Voice Cloning
+Assume there are some reference audios in `./ref_audio`
+```text
+ref_audio
+├── 001238.wav
+├── LJ015-0254.wav
+└── audio_self_test.mp3
+```
+`./local/voice_cloning.sh` calls `${BIN_DIR}/voice_cloning.py`
+
+```bash
+CUDA_VISIBLE_DEVICES=${gpus} ./local/voice_cloning.sh ${conf_path} ${train_output_path} ${ckpt_name} ${ge2e_params_path} ${add_blank} ${ref_audio_dir}
+```
+
+If you want to convert a speaker audio file to refered speaker, run:
+
+```bash
+CUDA_VISIBLE_DEVICES=${gpus} ./local/voice_cloning.sh ${conf_path} ${train_output_path} ${ckpt_name} ${ge2e_params_path} ${add_blank} ${ref_audio_dir} ${src_audio_path}
+```

+# VITS with AISHELL-3
+This example contains code used to train a [VITS](https://arxiv.org/abs/2106.06103) model with [AISHELL-3](http://www.aishelltech.com/aishell_3).
+
+AISHELL-3 is a large-scale and high-fidelity multi-speaker Mandarin speech corpus that could be used to train multi-speaker Text-to-Speech (TTS) systems.
+
+We use AISHELL-3 to train a multi-speaker VITS model here.
+## Dataset
+### Download and Extract
+Download AISHELL-3 from it's [Official Website](http://www.aishelltech.com/aishell_3) and extract it to `~/datasets`. Then the dataset is in the directory `~/datasets/data_aishell3`.
+
+### Get MFA Result and Extract
+We use [MFA2.x](https://github.com/MontrealCorpusTools/Montreal-Forced-Aligner) to get phonemes for VITS, the durations of MFA are not needed here.
+You can download from here [aishell3_alignment_tone.tar.gz](https://paddlespeech.bj.bcebos.com/MFA/AISHELL-3/with_tone/aishell3_alignment_tone.tar.gz), or train your MFA model reference to [mfa example](https://github.com/PaddlePaddle/PaddleSpeech/tree/develop/examples/other/mfa) (use MFA1.x now) of our repo.
+
+## Get Started
+Assume the path to the dataset is `~/datasets/data_aishell3`.
+Assume the path to the MFA result of AISHELL-3 is `./aishell3_alignment_tone`.
+Run the command below to
+1. **source path**.
+2. preprocess the dataset.
+3. train the model.
+4. synthesize wavs.
+ - synthesize waveform from `metadata.jsonl`.
+ - synthesize waveform from a text file.
+
+```bash
+./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.
+```bash
+./run.sh --stage 0 --stop-stage 0
+```
+
+### Data Preprocessing
+```bash
+./local/preprocess.sh ${conf_path}
+```
+When it is done. A `dump` folder is created in the current directory. The structure of the dump folder is listed below.
+
+```text
+dump
+├── dev
+│ ├── norm
+│ └── raw
+├── phone_id_map.txt
+├── speaker_id_map.txt
+├── test
+│ ├── norm
+│ └── raw
+└── train
+ ├── feats_stats.npy
+ ├── norm
+ └── raw
+```
+The dataset is split into 3 parts, namely `train`, `dev`, and` test`, each of which contains a `norm` and `raw` subfolder. The raw folder contains wave and linear spectrogram of each utterance, while the norm folder contains normalized ones. The statistics used to normalize features are computed from the training set, which is located in `dump/train/feats_stats.npy`.
+
+Also, there is a `metadata.jsonl` in each subfolder. It is a table-like file that contains phones, text_lengths, feats, feats_lengths, the path of linear spectrogram features, the path of raw waves, speaker, and the id of each utterance.
+
+### Model Training
+```bash
+CUDA_VISIBLE_DEVICES=${gpus} ./local/train.sh ${conf_path} ${train_output_path}
+```
+`./local/train.sh` calls `${BIN_DIR}/train.py`.
+Here's the complete help message.
+```text
+usage: train.py [-h] [--config CONFIG] [--train-metadata TRAIN_METADATA]
+ [--dev-metadata DEV_METADATA] [--output-dir OUTPUT_DIR]
+ [--ngpu NGPU] [--phones-dict PHONES_DICT]
+ [--speaker-dict SPEAKER_DICT] [--voice-cloning VOICE_CLONING]
+
+Train a VITS model.
+
+optional arguments:
+ -h, --help show this help message and exit
+ --config CONFIG config file to overwrite default config.
+ --train-metadata TRAIN_METADATA
+ training data.
+ --dev-metadata DEV_METADATA
+ dev data.
+ --output-dir OUTPUT_DIR
+ output dir.
+ --ngpu NGPU if ngpu == 0, use cpu.
+ --phones-dict PHONES_DICT
+ phone vocabulary file.
+ --speaker-dict SPEAKER_DICT
+ speaker id map file for multiple speaker model.
+ --voice-cloning VOICE_CLONING
+ whether training voice cloning model.
+```
+1. `--config` is a config file in yaml format to overwrite the default config, which can be found at `conf/default.yaml`.
+2. `--train-metadata` and `--dev-metadata` should be the metadata file in the normalized subfolder of `train` and `dev` in the `dump` folder.
+3. `--output-dir` is the directory to save the results of the experiment. Checkpoints are saved in `checkpoints/` inside this directory.
+4. `--ngpu` is the number of gpus to use, if ngpu == 0, use cpu.
+5. `--phones-dict` is the path of the phone vocabulary file.
+6. `--speaker-dict` is the path of the speaker id map file when training a multi-speaker VITS.
+
+### Synthesizing
+
+`./local/synthesize.sh` calls `${BIN_DIR}/synthesize.py`, which can synthesize waveform from `metadata.jsonl`.
+
+```bash
+CUDA_VISIBLE_DEVICES=${gpus} ./local/synthesize.sh ${conf_path} ${train_output_path} ${ckpt_name}
+```
+```text
+usage: synthesize.py [-h] [--config CONFIG] [--ckpt CKPT]
+ [--phones_dict PHONES_DICT] [--speaker_dict SPEAKER_DICT]
+ [--voice-cloning VOICE_CLONING] [--ngpu NGPU]
+ [--test_metadata TEST_METADATA] [--output_dir OUTPUT_DIR]
+
+Synthesize with VITS
+
+optional arguments:
+ -h, --help show this help message and exit
+ --config CONFIG Config of VITS.
+ --ckpt CKPT Checkpoint file of VITS.
+ --phones_dict PHONES_DICT
+ phone vocabulary file.
+ --speaker_dict SPEAKER_DICT
+ speaker id map file.
+ --voice-cloning VOICE_CLONING
+ whether training voice cloning model.
+ --ngpu NGPU if ngpu == 0, use cpu.
+ --test_metadata TEST_METADATA
+ test metadata.
+ --output_dir OUTPUT_DIR
+ output dir.
+```
+`./local/synthesize_e2e.sh` calls `${BIN_DIR}/synthesize_e2e.py`, which can synthesize waveform from text file.
+```bash
+CUDA_VISIBLE_DEVICES=${gpus} ./local/synthesize_e2e.sh ${conf_path} ${train_output_path} ${ckpt_name}
+```
+```text
+usage: synthesize_e2e.py [-h] [--config CONFIG] [--ckpt CKPT]
+ [--phones_dict PHONES_DICT]
+ [--speaker_dict SPEAKER_DICT] [--spk_id SPK_ID]
+ [--lang LANG]
+ [--inference_dir INFERENCE_DIR] [--ngpu NGPU]

+ --phones_dict PHONES_DICT
+ phone vocabulary file.
+ --speaker_dict SPEAKER_DICT
+ speaker id map file.
+ --spk_id SPK_ID spk id for multi speaker acoustic model
+ --lang LANG Choose model language. zh or en
+ --inference_dir INFERENCE_DIR

+ --ngpu NGPU if ngpu == 0, use cpu.
+ --text TEXT text to synthesize, a 'utt_id sentence' pair per line.
+ --output_dir OUTPUT_DIR
+ output dir.
+```
+1. `--config`, `--ckpt`, `--phones_dict` and `--speaker_dict` are arguments for acoustic model, which correspond to the 3 files in the VITS pretrained model.
+2. `--lang` is the model language, which can be `zh` or `en`.
+3. `--test_metadata` should be the metadata file in the normalized subfolder of `test` in the `dump` folder.
+4. `--text` is the text file, which contains sentences to synthesize.
+5. `--output_dir` is the directory to save synthesized audio files.
+6. `--ngpu` is the number of gpus to use, if ngpu == 0, use cpu.
