CMU Sphinx / Forums / Help: Mixture Gaussians doesn't match mean/var

Hello,

I am running the preliminary training run and am getting the following error.

MODULE: 11 Force-aligning transcripts (2010-05-09 22:36)

Phase 1: Cleaning up directories:
logs... output... qmanager...

Phase 3: Creating dictionary for alignment...

Phase 4: Creating transcript for alignment...

Phase 5: Running force alignment in 1 parts

Force alignment starting: (1 of 1)

sphinx3_align Log File

FATAL_ERROR: "cont_mgau.c", line 582: C:/Working/sphinx/tutorial/doheny/model_parameters/doheny.falign_ci_cont/mixture_weights: #Mixture Gaussians(153) doesn't match mean/var parameters(156)
FAILED

Failed to run sphinx3_align

I do not understand the error, nor how to resolve it. Any assistance would be
helpful.

Thanks.

Seems that the mdef file and the mean and variances files are not in sync. Is
this a sphinx train configuration issues because it seems that sphinx train
should be generating these files on its own.

No, it isn't

You need to check the log how models for forced alignment were built. This is
done on previous stage 10. Most likely the models were not updated for some
reason like permision issue.
