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?
