Speech Synthesis (TTS) training in another language
I'd like to train my own TTS model in Italian, using the portion of the MAILABS dataset (~18 hours). If I train the Tacotron 2 model with this dataset (16 kHz) can I fine tune from a pre-existing English model? I think that would increase performance but I didn't find any tutorial or example that performs it. Another question is whether vocoder training would be necessary or whether the English/Chinese pre-trained vocoders give acceptable performance even in a different language such as Italian. Last question is if the two end-to-end models, FastPitch_HifiGan_E2E and FastSpeech2_HifiGan_E2E, can be trained or fine-tuned from pre-existing checkpoints avoiding the need to train both Spectrogram Generator and Vocoder.
Thanks in advance for your answers
