Are they really showing us fucking Patapon gameplay?

Is there such a thing as a Speech-to-Speech model to de-accent tutorial videos? Sometimes an otherwise good tutorial for 3D modeling/animation stuff has an accent too thick and it just hampens the learning experience when I need to make a conscious effort to decipher speech.
I have a feeling this would be annoying amount of work with splicing and timing and wouldn't actually be worth it.
