Re: [gnuspeech-contact] a Python wrapper for the TRM

[David Hill]

Hi Leif,

I will respond to the license question shortly but, in the meantime, I wonder 
what you have in mind for a bare TRM package that simply converts incoming 
parameter frames into audio samples. I am sure you are aware that there is much 
more to speech in any language than the ability to "play" the TRM.

There are matters of the dynamic state changes that represent articulation, and 
questions of rhythm and intonation, not to mention the business of how words 
are pronounced (text-to-phonetic-representation conversion), all of which are 
embodied on the Monet and TTS client Apps.

If you are interested in working on the project I hope you have read up on the 
background documentation which explains much of this, and I would welcome your 
contribution. We really need some good people to help finish the port from the 
original NeXT version (which was compete) and then work on improving it. A 
major need is for completion of the editing facilities in Monet, which exist 
only as stubs at present.

Monet is really key to creating the text-to-speech rules for different 
languages, and it is the TTS client that is intended as the "speaking" service 
for other Apps that need text-to-speech. Obviously, improving the quality of 
the rules for speaking English also requires work with Monet (when it is 
complete).

The tube model by itself may be useful in its own right for psychophysical 
experiments. The "Synthesizer" App -- which basically provides an interactive 
interface to the TRM -- is an important tool for use with Monet in developing 
the posture specifications for an arbitrary language, and also requires some 
further work and testing, though the basic system functions well.

I shall be interested in your reply.

HTH.

All good wishes.
