Pretrained Models

Download our pretrained English models from huggingface. We provide an Watemark Encodec model, a pretrained English model on GigaSpeech XL set, and a pretrained Mandarin model on internal data (25,000 hours).

After downloading the files, put them under this repo, like:

SSR-Speech/
    -data/
    -demo/
    -pretrained_models/
    ....

Training

To train an SSR-Speech model, you need to prepare the following parts:

  1. Prepare a json file saving data in the following format (including utterances and their transcripts):

    {
"segment_id": "audio1",
"wav": "/data/audio1.wav",
"trans": "I like SSR-Speech.",
}
{
"segment_id": "audio2",
"wav": "/data/audio2.wav",
"trans": "SSR-Speech can do both zero-shot speech editing and text-to-speech!",
}
...

  2. Encode the utterances into codes using e.g. Encodec. Run:

export CUDA_VISIBLE_DEVICES=0
cd ./data
JSON_PATH='/data/test_gigaspeech.json' # change to your path
SAVE_DIR='/data/gigaspeech' # change to your path
ENCODEC_PATH='./pretrained_models/wmencodec.th' # change to your wmencodec path
DATA_NAME='gigaspeech' # change to yours
python encode.py \
--dataset_name ${DATA_NAME} \
--save_dir ${SAVE_DIR} \
--encodec_model_path ${ENCODEC_PATH} \
--json_path ${JSON_PATH} \
--start 0 \
--end 10000000

Here, JSON_PATH is the path where the json file was saved, SAVE_DIR is the path where the processed data will be saved, ENCODEC_PATH is the path of a pretrained encodec model and DATA_NAME is the saved name of the dataset. Here the start and end indexes are used for multi-gpu processing.

  1. Convert transcripts into phoneme sequence. Run:
JSON_PATH='/data/test_gigaspeech.json' # change to your path
SAVE_DIR='/data/gigaspeech' # change to your path
DATA_NAME='gigaspeech' # change to yours
python phonemize.py \
--dataset_name ${DATA_NAME} \
--json_path ${JSON_PATH} \
--save_dir ${SAVE_DIR}

Add language='cmn' in Line 47 (phonemize.py) when you process Mandarin.

  1. Prepare manifest (i.e. metadata). Run:
JSON_PATH='/data/test_gigaspeech.json' # change to your path
SAVE_DIR='/data/gigaspeech' # change to your path
DATA_NAME='gigaspeech' # change to yours
SAVENAME='test' # change to yours
python filemaker.py \
--dataset_name ${DATA_NAME} \
--json_path ${JSON_PATH} \
--save_dir ${SAVE_DIR} \
--savename ${SAVENAME}
  1. Prepare a phoneme set (we named it vocab.txt)
SAVE_DIR='/data/gigaspeech' # change to your path
DATA_NAME='gigaspeech' # change to yours
python vocab.py \
--dataset_name ${DATA_NAME} \
--save_dir ${SAVE_DIR}

Now, you are good to start training!

cd ./z_scripts
bash e830M.sh

If your dataset introduce new phonemes (which is very likely) that doesn't exist in the giga checkpoint, make sure you combine the original phonemes with the phoneme from your data when construction vocab. And you need to adjust --text_vocab_size and --text_pad_token so that the former is bigger than or equal to you vocab size, and the latter has the same value as --text_vocab_size (i.e. --text_pad_token is always the last token). From our experience, you can set --text_vocab_size to 100 for an English model and 200 for a Mandarin model.

Training WaterMarking Encodec

To train the Watermarking Encodec, you need to:

  1. install our audiocraft package,
cd ./audiocraft
pip install -e .
  1. prepare data (for training, validataion and test), e.g.
python makefile.py
  1. change the settings in ./audiocraft/config/ to your own and start training,
dora run -d solver='compression/encodec_audiogen_16khz' dset='internal/sounds_16khz'
