If all values in a frame are 0.0, extracted mel-cepstral coefficients become NaN.
For example,

% x2x +sf cmu_us_arctic_slt_a0001.raw | bcut -s 0 -e 399 | window -l 400 -L 512 -w 0 -n 1 | mcep -a 0.42 -m 12 -l 512 | dmp +f 
0       1.89489
1       0.822089
2       0.620753
3       0.66053
4       0.371214
5       0.548679
6       0.277446
7       0.43197
8       0.195604
9       0.194137
10      -0.0562655
11      0.0574899
12      -0.0505603

% x2x +sf cmu_us_arctic_slt_a0001.raw | bcut -s 0 -e 399 | sopr -m 0.0 | window -l 400 -L 512 -w 0 -n 1 | mcep -a 0.42 -m 12 -l 512 | dmp +f
0       nan
1       nan
2       nan
3       nan
4       nan
5       nan
6       nan
7       nan
8       nan
9       nan
10      nan
11      nan
12      nan

This problem sometimes occurs in silence.
Please re-extract mel-cepstral coefficients from the raw file which caused this problem 
and check whether it includes NaN or not.
