Extract the supportive data

using the following scripts, extract pitch statistics

bash

tar -xzf dataset_splits.tar.gz

cd extract-supportive-data
HYDRA_FULL_ERROR=1 python3 ./scripts/extract_sup_data.py \

Training FastPitch

training for about 800 epochs, with CosineAnnealing sched. and max_steps 200,000 for lr to decay overtime.

val_loss didn't decrease lower that about 0.77xx

val_loss = mel_loss + dur_loss + pitch_loss + energy_loss

Training HiFiGAN

training for about 40 epochs, stoped the training based on quality checking by listening to audios
