sam: Couldn’t open prompts file

Tuesday, January 26th, 2010

I want to use my German backup folder with sam. I have to choose the specific paths to the specific backup files:

user-generated

I am using the following path for the jconf file (I had to look into this blog post): /usr/share/kde4/apps/simond/default.jconf

This is the current content of the file /home/am3msi/Documents/201001/model/20100126-try-to-restore-german.sam:

/home/am3msi/Documents/201001/model/hmmdefs
/home/am3msi/Documents/201001/model/tiedlist
/home/am3msi/Documents/201001/model/model.dict
/home/am3msi/Documents/201001/model/model.dfa
/home/am3msi/Documents/201001/model/training.data/
/usr/share/kde4/apps/simond/default.jconf
/home/am3msi/Documents/201001/model/lexicon
/home/am3msi/Documents/201001/model/model.grammar
/home/am3msi/Documents/201001/model/model.voca
/home/am3msi/Documents/201001/model/prompts
/home/am3msi/Documents/201001/model/training.data/
/home/am3msi/Documents/201001/model/tree1.hed
/home/am3msi/Documents/201001/model/wav_config
16000
/home/am3msi/Documents/201001/model/prompts

Now, I click the Build model button.

build-log

1. I pressed the Build model button.
2. The Build log indicates that it worked out. Great. I assume that the previously existing files
/home/am3msi/Documents/201001/model/hmmdefs
/home/am3msi/Documents/201001/model/tiedlist
/home/am3msi/Documents/201001/model/model.dict
/home/am3msi/Documents/201001/model/model.dfa
have been replaced by new ones (probably with the identical content).

Now I want to test the model. So I press the Test model button. sam displays an error message:

Couldn’t open prompts file for reading: /home/am3msi/Documents/201001/model/training.data/

Why is that? What went wrong? Let’s take a look at the paths to the test files:
/home/am3msi/Documents/201001/model/training.data/
/usr/share/kde4/apps/simond/default.jconf
/home/am3msi/Documents/201001/model/prompts

The paths are correct. I am trying the following: I copy the prompts file to the training.data folder. But this didn’t solve my problem.

My guess is that there is a bug with sam. At least, it is possible to build a speech model with sam (from my German backup files). That is a good start. That means that my German wav recordings, my dictionary, my prompts aren’t lost.

My next step will be to take a closer look at simon. I will try to use my German backup files with simon. They worked with sam (only the Test model function failed, but the Build model function obviously worked). And I hope that they will work with simon, too.

sam couldn’t open julius jconf file

Tuesday, August 11th, 2009

I want to figure out how sam works.

jconf

1. I pressed Test model.
2. About 30 seconds later the error message Couldn't open julius jconf file: "". appeared.
3. I guess that I have to define a path for the JConf file. I think that I will give the following file a try: /home/liberty/200908/speech2text/trunk/simond/default.jconf.

By the way, forget about the red question mark in the screen shot of the previous post. The paths are as follows:
/usr/share/kde4/apps/simon/model/tree.hed
/usr/share/kde4/apps/simon/model/wav_config

I am getting the following error message:

recognizing

I get this error message even if I activate/connect simon/ksimond. I guess I have to use a different default.jconf file (located at a different location) because “relative paths must be relative to THIS FILE“.

I am giving the following location a try: /home/liberty/.kde/share/apps/simond/models/a/active/julius.jconf. It seems to work:

test-log

And this could be the overall recognition rate. But it isn’t. Just about 49 % were recognized correctly. I think that I will listen to some of the wav files. Maybe I will have to throw away some of the training samples?
