[RPG] Does casting pass without a trace prevent other verbal component spells

dnd-5espellsstealth

The PHB states under the spell p. 264

A veil of shadows and silence radiates from you,
masking you and your companions from detection.
For the duration, each creature you choose within 30
feet of you (including you) has a +10 bonus to Dexterity
(Stealth) checks and can’t be tracked except by magical
means. A creature that receives this bonus leaves
behind no tracks or other traces of its passage.

The line "shadows and silence radiates from you" leaves me questioning if this spell works similar to silence spell and if so, would that prevent any verbal component spells used by the other creatures in the area of effect?

Best Answer

It is a veil of shadows and silence. A real veil is a kind translucent curtain (either as a room/window hanging, or part of one's clothing). A veil of silence would block most but not all sound — hence why you get merely a very good bonus to Stealth rather than some explicit effect that says you're impossible to detect by sound.

A veil — being merely a screen — of shadows and silence only makes it harder for those outside to easily perceive those inside the area of effect. It doesn't say that spellcasting that requires verbal components is made impossible, or that perception for those inside is at all impaired (i.e., those inside can see and hear just fine!), so the interior area is unaffected.
