Speaker Adaptation in HTK 3.4.1

Hi All,

 

I'm attempting to adapt my tied-state, context-dependent triphone system to a set of data from a novel speaker via mllr/cmll. Models have 16 mixture components, except for sil which is 32. I'm running 3.4.1 in an ubuntu environment. I'm following the guidelines given in the HTK book 3.4.1 pages 43-45.

I have no problem creating the regression tree or creating the global transform. When using the global transform as an input transform for the second pass of HERest to create either a new transform or an updated model set, I encounter a segmentation fault. Find below the results of the calls to HHEd and HERest

Segmentation fault (core dumped)


-------------------------------------------------------

At which point I encounter the segmentation fault...

 

Do you have any suggestions as to why I might be encountering this problem? Interestingly, I have succeeded with an identical process on a different language model with different phones on this same machine, so I don't believe it's an issue with the installation of HTK. I think the suspect may be the regression tree, though I'm not sure. Additionally, I've found someone else with what appears to be the same problem here.

 

Thanks for your time!

Eric

Have you tried to get any information from your core dump with gdb? That may give you some information regarding where (HERest?) failed. Your observation regarding phones may be pertinent, since it involves strings which may be badly interpreted by pointers.

Sorry for the late reply Colbec.


Running the command from within gdb:

##############

gdb /usr/local/bin/HEREst

(gdb)  run -A -T 1 -D -a -C model/config -C adapt/config.rc -S scripts/mfc.scp -I data/wintri.mlf -H model/hmm13/globals -H model/hmm13/hmmdefs -M adapt -J adapt/xforms cmllr1 -J adapt -h '*/%%%%%%*_*.mfc' tiedlist

##############

Yields the output:

Program received signal SIGSEGV, Segmentation fault.
CompXForm (mp=0x7ffff78f2d20, xform=0x7ffff5a59148, ai=0x0) at HAdapt.c:2299

##############


calling: (gdb) where

yields:

##############

I'm inexperienced with reading gdb output, is there anything obvious that I'm missing?

I'm fairly sure now that the fault is due to memory usage in HAdapt, but whether or not that memory usage is due to a bug or to my data is unclear. Unfortunately, the segmentation fault happens too quickly for me to monitor the memory usage via top.

Rolling back to monophones did allow the adaptation to complete successfully.

It seems to be pointing at HAdapt, on or about line 2299.

A quick google for htk hadapt 2299 does not show anything much to me, so if it is a bug it must be a very obscure one. I guess you could ask yourself what you may be doing that is way off in left field.

As we guessed, strings and pointers seem to be involved. The var ai seems to be a struct that holds a list (LIFO FIFO queue or something) that at some points to a memory location in ai->next and if next is not in the list then clunk.

Two suggestions: put the question (now that you have details) to the folks at HTK (see for example http://htk.eng.cam.ac.uk/develop/report_bug.shtml) and continue what you are doing, changing the data inputs to see if patterns emerge.
