This sounds like an interesting project - what sort of speech-specific
things did you have in mind and how would the application be used in practice? I
know a little about formants and things (I had a PhD student working on CELP
coders once), and some signal processing, so I may be interested in joining
you in a useful project. In fact I have a friend who I think has one of those
CSL devices - I'll see if she will let me take a look at it.

Hello everyone...
I work in the Health Service (UK), with an interest in speech and voice
disorders. Here's the thing. Instrumentation is too expensive for most
centres. For example, top of the tree...

We're lucky and got one. But it's just a nice sound card and mic, with some
(not great, IMHO) application software. I came across Audacity recently
because a colleague is using it for voice recording and editing. She lives
in
Germany but then has to travel to Berne (Switzerland) to do the speech
analysis(!)
It seems to me Audacity could form the basis of a cheap-and-cheerful
alternative. It has a MUCH better interface, and can be paired up with sound
card and mic according to budget. There are some speech-specific things -
spectral analysis, measuring voice parameters - where the development would
be
needed. First impression is that many could be done using Nyquist, with C++
bits as necessary.
One of the issues with commercial systems is that they all measure stuff
slightly differently. Nobody quite understands how because the algorithms
are
confidential. Open source would be a benefit here, more than just the lack
of
cost.
So - is anyone working in this area already? If not, I know a bit of C++
(Win32 API using oldish Borland IDE, pre C++ Builder), but I've never worked
on an open source project before. Any advice?
Thanks - Mike
BTW, sorry if this is the wrong forum for the post, but I figure you would
know what developments were going on.
