I ran into a problem with step 10 with a missing proto error so I decided to script everything in bash. Its pretty rough but it seems to work. With a small vocabulary set and with a pruned lexicon, it completes in seconds. If anyone is interested, let me know where to upload the files. As always, use at your own risk - cannot stress that enough.

I'm in a desperate need to create acoustic model for my language (which is not supported here in VoxForge). I've got very little vocabulary because it contains only about fifteen words. I follow this tutorial http://www.speech.cs.cmu.edu/sphinxman/scriptman1.html and unfortunately I cannot use Sphinx Wiki because they've got technical difficulties all the time. I find this tutorial somehow insufficient so I downloaded files from VoxForge Germany model. Based on this model and tutorial I created similar structure of files and directories for my language. I know I ask for much but I would be really greatful if somebody experienced can guide me through the process of training acoustic model. I've got little training data and I'm going to have much more but first of all I need to know how to follow this whole process with the simplest set of data - just to ensure that I can do it.

I have recorded and re-recorded the prompts, checked the phoneme construction but still that combination tops the error charts. So I set up a test routine that plugs away at that issue and records results. Using the grammar: FILTER ( ALPHA BRAVO CHARLIE PAPA ) FOCUS ( ALPHA BRAVO CHARLIE PAPA ) the error results after testing the possibilities 8 times: +------+--------------+----------+----------+-------+ | thid | thname | thmax | thmin | therr | +------+--------------+----------+----------+-------+ | 286 | FILTER ALPHA | -20260.4 | -20260.4 | 7 | | 283 | FILTER PAPA | -19547.2 | -18447.2 | 2 | +------+--------------+----------+----------+-------+ So after 8 attempts to say filter alpha only one was correct and the score was extreme. filter papa was also a problem but much less so, recognized 6 times correctly and two times wrongly. When filter papa was recognized the score was in a fairly narrow range which indicates some consistency. The combinations with FOCUS were all registered correctly every time, and both FOCUS and FILTER were fine with CHARLIE and BRAVO. Examining the detailed output from Julius shows that sometimes filter alpha is seen in pass 1 and then the engine decides that is wrong in pass2. I guess my question is, is my problem with filter, or alpha or filter alpha? Is this a known difficulty, is there a parameter that can sensibily be tweaked in Julius in this case? FILTER is in my lexicon twice, with "f ih l t ax" and "f ih l t ax r".

I'm writing to comment on a technical issue that I'm not sure if you are aware of: The general rule I have seen with ASR systems is that, as the amount of training data increases, it eventually becomes necessary to add more acoustic model parameters in order to get the full benefit of the additional data. On the other hand, using too many acoustic model parameters may cause overfitting (in other words, the system starts modeling quirks of the training data to the point where the system's performance on non-training data is worsened). Thus, you may need to periodically tune the number of acoustic model parameters you are using. I suppose the easiest way to do this is to create a test set which does not overlap with the training set, and measure word recognition accuracy on the test set for various acoustic model sizes. One way to increase the number of parameters is to use more Gaussians in the Gaussian mixtures. (One way to do this in HTK is to add one or more additional mixup stages. This has the advantage that you can use your test set to compare recognition accuracy before and after the mixup, so that you can obtain your recognition accuracy numbers without having to retrain a system from scratch each time.) Another way to increase the number of parameters is to move from monophones to triphones (unless you are using triphones already). Another way is to reduce the amount of state-tying.

I tried to set my LANG, LC_ALL environment variables and other LC=XXX variable's value to de_DE.ISO8859-1 ( on FreeBSD machine ) but no difference. Could somebody tell me what I am doing wrong? Any help would be appreciated.

Lately I've been absorbing everything I can get my hands on regarding speech recognition for a few projects I have in mind. I've read Arthur Chan's letter to the community and I agree with his assessment. In addition, I'm hoping this site will be instrumental in bringing the community it's first open source text/speech corpus. I spent more than a few hours playing with Sphinx in it's various incarnations tonight and well ... it's a start. I'll likely be downloading from this site soon in an attempt to make my own acoustic model. (Right after I get a decent mic) But anyway, on to the reason for this message: Why don't we auto generate a couple hundred hours of text to speech from festival and any cheap commercial text-to-speech engine out there that we can get our hands on? Sure, it won't be as good as a human read corpus, but with all the different voices and accents (i.e. british vs. american, and male vs female) it's got to be better than nothing, right? Besides, is bad speech really undesirable? Don't we want less than perfect samples? Won't that make the model more robust? What do you think? Cheap couple hundred hours? http://www.voxforge.org/home/forums/message-boards/acoustic-model-discussions/humans-are-great-but-why-not-use-commercial-and-oss-text-to-speech-engines-too Sat, 31 Mar 2007 02:11:20 -0500 http://www.voxforge.org/home/forums/message-boards/acoustic-model-discussions/acoustic-model-creation-error-in-step-10 I'm building a new voice grammar and repeately I get an error in step 10 making hmm 13.

Why do we need N-grams? Is it simply for word separation?

(I'm not sure if it would be; I'm used to training with speech files separated into sentences but I don't know if that's necessary.) But if so, maybe an automated forced alignment against the text could be used to do that.  http://www.voxforge.org/home/forums/message-boards/acoustic-model-discussions/librivox-data Thu, 12 Oct 2006 13:28:04 -0500
