Actually, we don't know the longevity of vampires in the Witcher lore canon wise except from what Regis reveals about himself (as a higher vampire). I know it's rather difficult keeping general supernatural lore out there separate from specific fictional worlds (for one thing, I'm pretty sure Regis doesn't sparkle :p )

As for vampire language, I don't think there was one specific word to describe it. Honestly I prefer "language" in general over "speech" but that's because I'm used to referring to a particular tongue one speaks in as "language" and not "speech" (I don't know speech means for you, but generally here it means more along the lines of sound/pronounciation).
