Troubles with Robust Group Tutorial

[laex_]

Hi!

Yesterday I found the "Robust Group Tutorial" (http://www.speech.cs.cmu.edu/sphinx/tutorial.html) and this seems quite nice. But unfortunately it doesn't work for me - either I'm pretty stupid or there are missing files on my machine...?
(I wanted to use SphinxTrain and Sphinx4)

1)
Section: Setting up Sphinx4, "Tutorial Setup":
>>>
Section under construction
...
perl scripts/setup_tutorial.pl an4
...
End of section under construction
<<<

There simply is no "setup_tutorial.pl" in the whole sphinx4 folder.

2) And further down (if I go on disregarding the first problem), section: "How to perform a preliminary decode", first command:
>>>
perl scripts_pl/make_feats.pl -ctl etc/an4_test.fileids
<<<

I get this output:
>>>
C:_alex\tutorial\an4>perl scripts_pl\make_feats.pl -ctl etc\an4_test.fileids
-cfg not specified, using the default ./etc/sphinx_train.cfg

Again, a file "an406-fcaw-b.mfc" does not exist, nowhere in the whole tutorial directory...

Any ideas? Thanks a lot in advance for any help!

About setup_tutorial.pl: It is in SphinxTrain. -a

[laex_]

?
Well, the setup_tutorial.pl in the SphinxTrain folder was - according to the tutorial - executed several steps before that already, after compiling the trainer...

Again the original cite from the tutorial:
<cite>
cd sphinx4

If you installed AN4

perl scripts/setup_tutorial.pl an4
</cite>
And then the file is simply not there. And there is nothing I could do wrong here (I suppose). Strange tutorial... :-)

Thanks for your comment, anyway.

This is a valid comment. I will forward this mail to the maintainer of the tutorial.

Hi,

I thought the "under construction" warning would be enough to suggest the sphinx-4 part in the tutorial shouldn't be used. My mistake for not being clear enough. I changed it to a paragraph stating the instructions are forthcoming. Sphinx4, as is, doesn't have the support files to be used by this tutorial, even though the intention is to create them.

Regarding the problem of mfc not found, this is in fact caused by the directory, not the file, not existing. The setup scripts for the other decoders (sphinx2, sphinx3, s3flat) would have created the missing directory structure.

Hi,

OK, thanks, I see... Of course I saw the "under construction" statement. But I think it would be great to state that Sphinx4 is not an option yet, already in the Introduction of the tutorial.
Because in fact it is never (!) said that you can't really choose it...

So long...
