[hts-users:02038] Re: Problem Feature Extraction

[wangxiang <wangxiang68@xxxxxxxxx>]

I read the code of SPTK and find when the theq() condition is not true, the mgcep exits.

I just wonder why some wave can't apply the theq condition?

When I listen to these waves, they seem to be normal ! Can anyone give me some paper about this theory?

Then it stops when error, and the units is not complete.
So can you give me some suggestion to solve it ?
Thanks!

Hi,

It will be harmful, since the feature extraction stops when the error raises. This means that you have incomplete features (and later cmp) files. 

You might then get not enough or no data for some units.

It means that determinant of Toeplitz+Hankel matrix, which is a coefficient matrix of a linear system in MGC analysis, is too small (< 1.0e-6).
You can modify this threshold via -f option as a smaller threshold

Does anyone know the reason for this warning  and  Is it harmful to the model training?

Thanks!
