[hts-users:02995] Re: Silent waveforms in synthesis with hts_engine

[Junichi Yamagishi <jyamagis@xxxxxxxxxxxx>]

Hi all,

Please ignore her mails. 

She is our MSc student and she confused my local HTS tools 
with publicly available HTS tools. 
 
Sorry for the confusions and thank you for kind replies.  

Regards,
Junichi

So as to Oura, the main difference between mel-cepstrum from SPTK and STRAIGHT is the scale, because of the Matalb process of waveform. So you can add the anergy to the mcep yourself when processing.
