cannot train new model with TTS tacotron2
# I want to train new model with my dataset for other language
# one case in my dataset json file is:
`{"audio_filepath": "./wav/4.wav", "duration": 5.6750625, "is_phoneme": 1, "original_text": "gAme sevvOm d%r b/rnamerizI | $enAxte moqe@iyy%te fe@lIye hozE @%st | ", "normalized_text": "gAme sevvOm d%r b/rnamerizI | $enAxte moqe@iyy%te fe@lIye hozE @%st | "}`

# and my confige file is:
