Re: [Kaldi-users] Feature extraction arguments for online recognizers

[Mailing l. u. f. U. C. a. U. <kal...@li...>]

Hi,
Unfortunately I think there is no other way to do this, but to change
the source code. As you might have already seen the feature extraction
parameters are hard-coded - e.g. here is a snippet from the main()
function:

// We are not properly registering/exposing MFCC and frame extraction options,
// because there are parts of the online decoding code, where some of these
// options are hardwired(ToDo: we should fix this at some point)
MfccOptions mfcc_opts;
mfcc_opts.use_energy = false;
int32 frame_length = mfcc_opts.frame_opts.frame_length_ms = 25;
int32 frame_shift = mfcc_opts.frame_opts.frame_shift_ms = 10;

To be honest I can't even remember which parts of the online code
should be fixed, and I don't have time to refactor the code at the
moment.
