[hts-users:00682] Re: mel-lsp extraction

[Ossama Abdel-Hamid <ossama_a@xxxxxxxxx>]

Hi Heiga,

I have a question about the features used in Blizzard challenges 2005 
and 2006. In 2005 you used STRAIGHT to extract a smooth spectral envelop 
parameters, then extracted mel-cepstral parameters from that spectral 
envelop. And in 2006 you extracted mel-lsp coeffiecients. My question is 
how did you extract mel-cepstral or mel-lsp from the spectral envelop? 
Did you use any of the SPTK tools, or you wrote a tool for that?

Best Regards,
Ossama Abdel-Hamid
