In Catalan, the log file is very similar to the English one. The output
wav files have the appropriated duration .. but the amplitude does not
represent speech: is almost zero, in some files, with a small pulse.
From my experience MLSA do generate complete silence with initial click
when predicted f0/mcep parameters aren't correct. For example if
different step is used or predicted f0 has negative sign in pau region
(this happens sometime too, I don't know why).
So the right way I think is to dump all predicted track and then look
for unusual things and their reason.
