While integrating the YMFM core into PinMAME, we found a potential timing inaccuracy issue for WPC pinball machines, for an explanation and slight discussion, see:
https://github.com/vpinball/pinmame/pull/124
We saw a similar issue already in the past, but worked around it with the old YM cores. Nowadays we try to do everything correctly, so maybe this is also why the same issue (e.g. way too slow speech output on WPC) does not appear in MAME (yet), too?
