Thanks. This issue has been fixed. I suspect you are using an out-of-date version of Kaldi. If you have done "svn up" and are still at revision 2256 or thereabouts, it means you have not updated your repository to the "new" sourceforge. See instructions at kaldi.sf.net on how to change.

Hi All, I just finished setting up the GPGPU environment and running the experiments in the Kaldi. In the beginning, I could not compile through all the cuda related programs with "undefined references" link errors, now I found a workaround by putting the cuda related ld flags "-lcublas" and "-lcudart" in the end (i.e. after -lpthread). My system is Ubuntu 12.04 with gcc 4.6.3. Just sending this in case you have the same problem. Bests, Chao |

Actually, the problem might also be that the "make install" part of the OpenFST installation failed, because there should be a file openfst-1.3.2/lib/openfst.a Type "make openfst_tgt" in the tools/ directory and see what happens Dan On Wed, May 8, 2013 at 10:30 AM, Daniel Povey <dp...@gm...> wrote: > There should be a soft link from "openfst" to "openfst-1.3.2".

Also, tools/openfst-1.3.2 itself should be symlinked as tools/openfst -- if not, let us know. But I am surprised that the directory is lib64 an not lib. This could be an OS-specific issue that I cannot recreate. -Arnab |

There should be a soft link from "openfst" to "openfst-1.3.2". See if it exists and try to figure out why not, if it does not.

You could call gmm-init-mono with the --bimary=false flag in which case the model file is saved as ASCII. Or you could use gmm-copy with the same flag. BTW, HCompV doesn't do what you said it does. You probably meant HHEd. But in general, it's best to understand Kaldi by itself and not try to map everything to the HTK world. -Arnab On Tue, May 7, 2013 at 12:11 PM, Arif Khan <ife...@gm...> wrote: > Hi, > > I am using kaldi for Aurora 2 experiments which are based on word based > training and recognition and not Monophones. > > My question is after executing the following command. > "Usage: gmm-init-mono <topology-in> <dim> <model-out> <tree-out> \n". > How can we view the contents of the model file "<model-out>" created. > > > In HTK we have CompV module, which copies the topology of hmm for different > phones/words from a single topology file and are > saved in a text format and we can view the hmm for different phones/words. > Do the same things happens after the gmm-inint-mono command.

Hi, I am using kaldi for Aurora 2 experiments which are based on word based training and recognition and not Monophones. My question is after executing the following command. "Usage: gmm-init-mono <topology-in> <dim> <model-out> <tree-out> \n". How can we view the contents of the model file "<model-out>" created. In HTK we have CompV module, which copies the topology of hmm for different phones/words from a single topology file and are saved in a text format and we can view the hmm for different phones/words. Do the same things happens after the gmm-inint-mono command. How can we view this. Any help will be highly appreciated. Thanks, Arif |

As written, it's primarily a command line tool, but it's designed in such a way that it should be possible to take the code and put it into other apps. But at the present time, you would have to have a fair amount of both speech expertise and familiarity with Kaldi, in order to be able to do this.

Thanks Dan, I was able to modify the script to recognize my Darwin version. Also, when I checked out 'kaldi-stable', this wasn't a problem; I must have originally downloaded a different version.

If you look in the standard recipes, there is a prototype topology somewhere e.g. in conf/topo.proto or somewhere like that that you could edit if you want to have more than 3 states. Regarding things like adding states for silence and short pause-- it sounds to me like you are trying to "literally translate" a HTK recipe. This is not a good idea, as Kaldi is a different toolkit with different ways of doing things. It will just do the right thing with regard to the number of Gaussians per state, so you don't have to really do anything.

It's possible that it will work for that version but the configuration script just doesn't know that, so you could possibly just modify it to accept this version and treat it as an earlier one.

Hi, I want to run Aurora 2.0 experiments with Kaldi. For that I need to model 18 state hmm for digits. and 5 state hmm for silence and 3 state hmm for short pause (between two consecutive digits). My question is: a) How we tie/share a state among different hmm models. b) I want to use iterative training, therefore will have to manipulate hmm in the middle of training for adding states for short pause and silence and increasing Gaussian mixtures per state, so How we modify hmm during the middle of training. In HTK we use HHED module to do this. Any help or reference material would be highly appreciated. Best regards, Arif |

Dear Kaldi Developers, I'm very new to Kaldi. Currently, I finished re-do the wsj recipe. My questions are: - How to generate the Kaldi result in ctm format? - How to read the *.ali files? - If I want to try is to re-train the WSJ model with new data, and we already have mlf files (phone and word with time information) of new data generated from HTK, is there any way to convert it to Kaldi alignment files format? It would be great if you could help me for this. Thank you. Sincerely yours, Sakriani Sakti |

OK, used -1 to mean "take till end of file". Instead of using a bool to accept larger segments at the end it's now a float (time in secs) till which an overshooting segment will be accepted. -Arnab On Thu, Apr 18, 2013 at 7:38 PM, Nagendra Kumar Goel <nag...@go...> wrote: > Arnab, > I prefer not to use soxi as its an overkill sometimes.

-1 is exactly representable as float. I'd say make it exactly -1. It's not pretty, but I don't see it hurting anyone either.

Arnab, I prefer not to use soxi as its an overkill sometimes. Sometimes the data may not even be in wav format (sure will convert before using feature extraction but that's a different pipe). How about if we make the syntax requirements more strict - like require the value to be exactly -1. The only issue will be that it's loaded as float, but we could take the difference and require that to be very small. This will help you catch bugs in your scripts early on while keeping me safe. I recall earlier there was some data that had incorrect segmentation (like end time was rounded off), causing scripts to unnecessarily fail for some segments. However that data has been cleaned up.

Subject: Re: [Kaldi-developers] extract-segments The reason I don't like the special value is that there is a check to reject segments that are too small.

The way I would have solved your particular problem is to get the start (which will be 0) and end times for the single utterance files, while keeping the segments format unchanged. You could use soxi to get the end time. Let me know if this works for you. -Arnab On Thu, Apr 18, 2013 at 6:35 PM, Nagendra Kumar Goel <nag...@go...> wrote: > I have been using this to mix in data that is segmented with data that > is sentence by sentence files.

I have been using this to mix in data that is segmented with data that is sentence by sentence files. I didn't care if its 0 or -1. Is there a specific reason you don't like it?

The reason I don't like the special value is that there is a check to reject segments that are too small. This is a command line option and is visible to the user. The special value (in the current code it's really an interval) is hidden and one can only know about it by reading the code. But the hidden option has a higher priority than the visible option. So while it is reasonable for a user to expect any segments with invalid start and end times (i.e. start >= end) to be rejected, sometimes the whole file may actually get included instead. This is, in fact, how we found the problem-- a scripting bug caused some end times to be 0, which went undetected till some process way down the line died due to a very big segment that shouldn't have been there.

Perhaps the condition should be "< 0" rather than "<= 0" ? If that is the problem.
