I've been taught to pronounce ∂ as /do:/, which does help quite a bit. No
idea how widely that is in use (or if that would be /du:/ or /doʊ/ in English).

I also find that distinguishing "dx dt" from "dx/dt" (or anything of the
sort) works largely by prosody rather than actually including "per" in the
latter. There's an upstep between each top-level multiplicand, I think.

Another, fairly transparent possible minor timesaver is to omit the /ɛ/ or
/i:/ from variables, if possible ("deef" rather than "dee f", etc.), but
it's not common IME.

Clearly there's room for further concision however.
