Slavery is commonplace in this setting. Slaves routinely have their tongues cut out, to prevent them organising a resistance movement, or back-chatting their owners.

The party has freed some slaves after decades of enslavement, and would like to **permanently** restore their ability to speak.

**What is the cheapest item, or lowest level spell, that can do this?**

* Healing magic that can restore missing body parts would suffice.
* A magical effect allowing the user to speak using a 'prosthetic voice' would also suffice.

I don't think the regular *Cure X Wounds* spells will work, as removing an entire appendage is a bit different to normal hit-point damage.

All 3.5 ed books are available.

This campaign is set in the world of *The Elder Scrolls: Morrowind*, on [Tamriel][1]. The slaves are mostly [Argonians][2] (lizard-people) and [Khajiit][3] (cat-people). Mechanically, they are Humanoid-type creatures.

The party's motivation for re-growing the slaves' tongues is to **symbolise their freedom**, by **permanently** reversing the trauma inflicted when they were enslaved. 

The various answers below also give temporary means of communicating with the slaves until the party is powerful enough to effect a permanent cure; these answers are also useful and appreciated.

Amusing anecdote: The *actual* reason the slaves are tongue-less is because this happened in the first session:

> DM (me) : "You have defeated the smugglers. You search the area and find three wooden crates, a boat, two slaves, and 10GP of coins."
>
> Players: "We talk to the slaves!"
>
> *[DM has no prepared dialog for the slaves, and has no idea what they would talk about.]*
>
> DM: ".... the slaves have had their tongues cut out!"
>
> Players: "That's terrible! We're going to lead a slave revolt and free all the slaves in Morrowind!"

And that's how the entire campaign got sidetracked from "Defeat the evil Dagoth Ur" to "Restore the tongues of every slave in Morrowind".
