What I've seen the most significant differences are 16kHz sampling rate and a slightly smaller window size for the batched synthesis.

I wonder what is lower limit of sample_rate for reasonable speech quality? Can it be tested just by resampling by something like ffmpeg?

This is correct. I haven't changed anything else other than the data loader.
