As a former owner of SF Extrema/Guarneri, B&W 802N, Merlin VSM, Dynaudio Confidence 5, Wilson Watt/Puppy (and many others), current owner of SF Amati & Cremona, my personal favorite for vocal is....
Dynaudio Consequence & Confidence 5.
Like electrostatis, secret lies in crossover, or lack of. Most 2 or 3 way speakers cross at vocal range and we all know what crossover can do to sound. Both speakers use midrange dome which covers vocal range without nasty crossover, the whole range is covered by one driver. Both speakers deliver real world bass unlike electrostatic. But penalty of either speaker is efficiency, <85db due to isobaric woofer design.
