Is this going to happen real-time? (I have no idea if consumer-grade
speech-to-text is fast enough for that.)

If so, I'd use a second PC (thus with independent sound system) with
a microphone & line-in(connected to a "Y"-split of the headphones' cable)
to capture both outgoing and incoming speech.
Unless you've got some very special sound hardware on the primary (VoIP
running) machine, capturing both input and output (where input isn't
itself mixed into the output) may just not be possible.

PS: note, that recording of conversations may have legal issues, so make
sure that at the start of the recording everyone involved knows it and
agrees to it. (this may not be relevant if the signal is used *only* for
speech-to-text and displaying of text, and neither text nor signal are
saved, but I'm not a lawyer.)  If you were from NSA, then you probably
wouldn't need to ask here in the first place...
