Configuring DecTalk Speech in Debian9?

[Chime Hart]

Well, I don't think I've seen any action here in a while? I would `love to 
switch back to Debian from Ubuntu. Last year, among David, Tony Baechler, and 
Okash, there were modifications posted, mostly speakup staging. At 1 point Tony 
posted a link to some dot deb files to enable speech, especially with a DecTalk. 
Well, Tony seems to have disappeared, but maybe some1 can please inform the best 
way of installing a more modern Speakup with a 64bit Debian9? In Ubuntu, I am 
still left with the same anoyances, involving sudden pitch, rate, and volume 
drops. Thanks so much in advance for any guidance
