[hts-users:04367] problems in "# Extracting MGC or MGC-LSP coefficients from raw audio".

["ALita Bao" <forgetfullucy@xxxxxxx>]

Hello all again,
When I was training a new model,
it comes the message
       "mcep : The log periodogram has '0', use '-e' option!"
in the process of
       "# Extracting MGC or MGC-LSP coefficients from raw audio".
what is this message mean?
Is this message will impact the result of my model?
Where can I use the '-e' option?
what parameters like when I use the '-e' option?
Thanks very very much.
