Re: [gnuspeech-contact] source code organisation

[David Hill]

Hi Eric,

I was away yesterday, as usual.

Several of your questions I shall only be able to answer properly/ 
fully when I've finished the Synthesizer port and moved onto the  
extraction & implementation of "real-time-monet".

You can probably "read" the source code even better than I can.   
Don't forget that the input text is parsed and converted to Monet  
input format.  At that point, the tone-group and foot boundaries are  
added, and the tone groups selected and the tonic chosen and this  
info is used to set the input format elements.  It is done on the  
basis of dictionary look-up, to get the stresses, which provide the  
foot boundaries, and the punctuation, which selects the tone group  
boundaries and tone-groups.  If there is no other information (e.g.  
bad punctuation) then defaults are used, so the tone group spans the  
whole sentence, the tonic is the last foot of the sentence, and the  
default tone group is tone group 1.  The short answer to your  
question is "during the parsing of the input to Monet".  The  
conversion to parameters is then carried out by methods within Monet,  
but there's no provision for changing the intonation/rhythm rules and  
data (unlike everything else), though they can be varied manually in  
particular syntheses.

I am not sure what this question really means.  Accessing the  
functionality of the TTS system is pretty well what Monet is all  
about.  The bit that is missing are Synthesizer, which allows the  
tube itself to be manipulated direcly.  But Monet allows all the  
other elements of the TTS system to be created/deleted/edited (well,  
the deletion for some things like rules is pretty kludgy since they  
are only renamed to a dead name).  Even the intonation can be varied  
by using the intonation window.  Perhaps you can be more explicit.

The original real-time monet is under "trillium/ObjectiveC/ 
Monet.realtime" in the archive:

        http://cvs.savannah.gnu.org/viewcvs/gnuspeech/?root=gnuspeech

Unfortunately, No, other than the self-documenting properties of the  
development environment and language -- unless Craig has kept  
whatever notes he made when he was writing the system.

Correct

You find out about this by visiting the repository as per URL above.

The names are pretty well self documenting, except where deliberate  
obscurantism was used (to hide password files, for example, and the  
directory names were not changed when the stuff was dumped on the  
Savannah site.

If you wanted to modify and recompile on the NeXT, you'd do well to  
consult with Craig &/or Len to see what extra paths need to be set up  
so ProjectBuilder can find everything.  The MusicKit is one obvious  
component that needs to be accessible.  Try compiling and see what  
the system complains it can't find and then figure out where the  
stuff is and add the paths to your search path.  If you are only  
dealing with Monet, you'd be better dealing with the Mac version and  
that shouldn't cause any problem.  If it does, Steve is you best  
source of info.  The NeXT is quite slow, of course.  You should find  
everything needed is on your NeXTStation if you really want to go  
that root.

Hope this helps.

All good wishes.
