Node 03: convert wav file with sox

August 23rd, 2009 by producer

liberty@liberty-desktop:~/.kde/share/apps/simon/model/samtestwav.data$ sox de27-02.wav -r 16000 -c 1 -s de27-02-test.wav

found similar entry here

I hope to be able to convert with sox from 48100 and 22050 to 16.000
why was there a different file size when converting 16000 hertz file to 16000 hertz file?

Dates in configure simon

July 13th, 2009 by producer

I just looked into the folder /home/liberty/.kde/share/apps/simond/models/a/src:

synchronisation

You can compare the folders above with the dates in configure simon:

configure

Obviously, the previous speech models are stored in /home/liberty/.kde/share/apps/simond/models/a/src.

HHEd and the ModelCompilationManager

May 23rd, 2009 by producer

Here is a code snippet from the modelcompilationmanager.cpp:

bool ModelCompilationManager::buildHMM10()
{
return execute(‘”‘+hHEd+”\” -A -D -T 1 -H \”"+htkIfyPath(tempDir)+”/hmm9/macros\” -H \”"+htkIfyPath(tempDir)+”/hmm9/hmmdefs\” -M \”"+htkIfyPath(tempDir)+”/hmm10/\” \”"+htkIfyPath(tempDir)+”/mktri.hed\” \”"+htkIfyPath(tempDir)+”/monophones1\”");
}

I have marked some things in the code snippet. Take a look into HHEd/Use if you want to know what
- the -A -D – T 1 means (probably standard options)
- the -H switch means (load macro file)
- the -H switch means (again)
- the -M switch means (store output in this directory)
- mktri.hed (this is probably the edCmdFile containing some commands)
- monophones1 (probably defines a set of HMMs)

modelcompilationmanager.cpp and HERest

May 23rd, 2009 by producer

Let’s take a look into the file modelcompilationmanager.cpp:

herest

You can see that the tool HERest is beeing invoked. The passing of the arguments -A -D -V -T 1 obviously guarantees that sufficient information is available (registration needed).

Obviously, there are several tools that are accessed by simon: HDMan, HLEd, HCopy, HCompV, HERest, HHEd, and HVite. These tools are not part of simon, you have to install them separately.
