software dectalk

[MICHAEL WEAVER <michaelweaver1 btinternet com>]

I was trying to get a decent software synthesiser for when I eventually 
get Orca running.
I heard the demo of Orca being used with a nice sounding synthesiser, 
possibly the dectalk only when I use my Windows Screenreader to download 
this synthesiser or purchase it, the onclick seems not to do anything on 
the website for this.
The default synthesiser I heard when trying to run Gnopernicus wasn't 
the best sounding of things, the speech was understandable just about 
but I use a laptop at my Linux grou[p and it tends to get nosy in Vox 
Bar or all the upstairs noise comes down to those of us discussing Linux.
How can I either get this synthesiser or if not could someone suggest 
one that might work just as well as the Dectalk?
On the website it talked about it being a good synthesiser in a noisy 
background which you can say Vox Bar is as it is a student place I think.
Hope someone can help.
