Tensorboard weird artefact on ground truth spectrogram

TTS (Text-to-Speech)
#1

Hi,
I have a similar looking tensorboard as the one exemple on the github of the project (https://github.com/mozilla/TTS/issues/337). But sometime on the ground truth, I have a weird artefact (a green rectangle) that is maybe just the silence trim but the models is struggling to replicate the green rectangle.

Is this normal behaviour ? Shouldn’t it be just deep blue if it’s silence ? Can it hurt performance ?

Thanks

it does not matter. The artifact is the padded part which you can ignore.

Is it worth sending in a PR to remove the padded part from the tensorboard plots/audio?

I don’t think so. it is good to see how it behaves for the padded part. If there is something wrong with the padding we see that.
