This is an implementation of the paper, based on the ESPnet. If you have any questions, please email to me(11930381@mail.sustech.edu.cn).

Follow the installation method of espnet.
You should use torch==1.7.1.

You should download LibriSpeech and LibriTTS manually.
LibriSpeech: run ./pretrain_asr.sh under egs/librispeech/asr (The recipe train ASR model on LibriSpeech train-clean-460)
LibriTTS: run ./pretrain_tts.sh under egs/libritts/tts (The recipe train TTS model on LibriTTS train-clean-460)

You should download TED-LIUM-1 manually. We give the punctuated TED_LIUM text under egs/tedlium/data path.
Execution directory(egs/tedlium/asrtts):
Run ./prepare_data.sh for preparing json file for training, and then run ./joint_training.sh for joint training.
