I am getting a problem in AM building for sphinx4 from sphinxtrain,

it says the following:

Fatal error: corpus.c, Line 1753: Expected mfcc vector len 39, got 26 (4082)

Can somebody suggest me what changes i need to do to get mfcc vector length of 39, the same data's were working fine for sphinx3 .

it looks you mistakenly changed configuration file. set vector length back to 13 instead of 39

You can use sphinx3 models in sphinx4 without any modifications.

Despite you found the "mention" somewhere, the vector size should be 13.
