I'm looking at running the dectalk code from github on a pi zero, which
seems a convenient way to avoid any proprietary parts. Initial test on a
desktop machine was easy to builds and worked out of the box.
However, I'm dreadful for getting bogged down in distractions and I don't
know whether good compatibilty will require a lot of work on the serial
interface (I anticipate possible problems with text buffering and
bidirectional data as with responses to commands). The Emic2 in particular
looks to have included significant work there.
I'd strongly encourage Frank or anyone else to look further into those
options (which all sound good) regardless of whether I get anywhere.

I really hope someone ports DECTalk to an STM32 with a DAC...
Or a Pico, which could do it without a DAC, using the PIO as a PWM analog
output driver.
