Tacotron2

PaddlePaddle dynamic graph implementation of Tacotron2, a neural network architecture for speech synthesis directly from text. The implementation is based on Natural TTS Synthesis by Conditioning WaveNet on Mel Spectrogram Predictions.

Dataset

We experiment with the LJSpeech dataset. Download and unzip LJSpeech.

wget https://data.keithito.com/data/speech/LJSpeech-1.1.tar.bz2
tar xjvf LJSpeech-1.1.tar.bz2

Then you need to preprocess the data by running preprocess.py, the preprocessed data will be placed in --output directory.

python preprocess.py \
--input=${DATAPATH} \
--output=${PREPROCESSEDDATAPATH} \
-v  \

For more help on arguments

python preprocess.py --help.

Train the model

Tacotron2 model can be trained by running train.py.

python train.py \
--data=${PREPROCESSEDDATAPATH} \
--output=${OUTPUTPATH} \
--device=gpu \

If you want to train on CPU, just set --device=cpu. If you want to train on multiple GPUs, just set --nprocs as num of GPU. By default, training will be resumed from the latest checkpoint in --output, if you want to start a new training, please use a new ${OUTPUTPATH} with no checkpoint. And if you want to resume from an other existing model, you should set checkpoint_path to be the checkpoint path you want to load.

Note: The checkpoint path cannot contain the file extension.

For more help on arguments

python train_transformer.py --help.

Synthesis

After training the Tacotron2, spectrogram can be synthesized by running synthesis.py.

python synthesis.py \
--config=${CONFIGPATH} \
--checkpoint_path=${CHECKPOINTPATH} \
--input=${TEXTPATH} \
--output=${OUTPUTPATH}
--device=gpu

The ${CONFIGPATH} needs to be matched with ${CHECKPOINTPATH}.

For more help on arguments

python synthesis.py --help.

Then you can find the spectrogram files in ${OUTPUTPATH}, and then they can be the input of vocoder like waveflow to get audio files.
