So this might be the rebel in me, but could you use Magical Tinkering to give a pebble the 'command word' and have the HS or SD use that pebble? ("Whenever tapped by a creature, the object emits a recorded message that can be heard up to 10 feet away.") This would be of course if the DM allowed Warforged to use the tattoos seeings how they dont have vocal cords but can still use Verbal spell casting which is based on Pitch and frequency so that could definitely be recorded :)
Warforged can speak, you're making some bizarre claims about how they speak. Using a magic rock to utter the command word would not work, as the entity uttering the command word must also be holding the needle.
