Deep Speech DnD 2023 – (Update) (The Language Of The Deep)

Deep Speech DnD

Looking for Deep Speech DnD so you reached the right spot. Here in this post, you will get the complete guide on Deep Speech 5E.

DnD has many different cultures and races that inhabit the universe. From Dwarvish, Gnomish, Elvish, and Common.

Each of these in-game languages will likely pop up at some point in the campaign. So it is really important for your in-game party to be diverse in terms of the languages it speaks. But then there are languages that have something special.

Alongside the 8 standard choices, there are 8 more exotic languages in the game. These include Draconic, Infernal, Primordial, Abyssal, Celestial, Sylvan, Undercommon, and Deep Speech.

These languages are far rare in appearance, however, can often be used to hide some interesting in-game secrets. And in this post, we will be taking a look at what Deep Speech in DnD is all about.

So without any delay let’s start the Deep Speech DnD guide.

Deep Speech is actually a rare language that is only commonly spoken among a few creatures, mostly Mindflayers and aberrations. Usually, you can expect these in-game creatures to be evil. But if you can speak deep speech, then you can communicate with these amazing creatures and find out more about their goals.

The strangest aspect of Deep Speech is that it is in fact a telepathic language. This is not always the case, but those that understand it can decide to communicate telepathically. But remember that this does not grant you any other telepathic skills in the game.

The Deep Speech uses are surprisingly few. Since very few creatures actually know it, and the few that do are extremely dangerous, there aren’t many times when you can find a reason to use it. And the in-game places that do use Deep Speech will probably use Undercommon more often. But it does provide you some potential for an interesting backstory if you select it as a second language.

You will need to prepare a convincing explanation as to how you actually know one of the most mysterious languages known in DnD. Since it is extremely rare and used by so few, you will require an interesting backstory to actually back it up.

The kinds of creatures that know Deep Speech are not ones that you did have a good chat with. First up are Aboleths which are actually underwater creatures that mostly live near the bottom of the in-game ocean.

They are ancient beings that can effectively use their telepathy to trick and enslave various creatures. Obviously, these things are not good at all. Joining them are the Beholders, and it is not hard to see why these guys are not that impressive.

They harbor a deep hatred for various creatures, and it would be really hard to reason with them even if you understood Deep Speech.

Mind Flayers are among the most well-known speakers of Deep Speech in the game, but try to have a casual conversation with them. These in-game creatures are inherently evil and seek only to control others.

They’re the right example of just how evil the Deep Speech language actually is. But if you know how to speak it, it may be really interesting to talk to the Mind Flayer and discover exactly what is taking place on inside their head. In all reality, that could be a very bad idea, but that is half the fun of DnD.

Should My Character Take It As A Language In DnD?

If you actually want to learn Deep Speech as an in-game language, there are some things to consider first. For starting, Deep Speech is not at all helpful for the most of the time. Other in-game standard languages have far greater chances to be helpful, so go for one of those if you prefer a more practical language.

On the other side, when Deep Speech does become helpful, you will be able to interact with certain opponents and items in a very interesting way. And you will likely be the only person at the party able to actually do it.

Overall, taking up Deep Speech is a choice that should provide a major hint to your in-game character’s past. It is not onlu a language that can be studied in a book like Gnomish or Dwarvish.

It is something that is mainly used by the most evil beings in the furthest corners of the game world. So be sure you fit your in-game character around that choice to actually make it cohesive. You can go any direction you want, but it is really important that the backstory fits the in-game character you will play.

What Does Deep Speech Sound Like In DnD?

This is something that is actually a bit less clear. Deep Speech does not provide a defined structure or sound to its language in the game. And that can make it a pain if you are a DM that likes to use these in-game languages and speak them to the gamers.

There are different places you could pull from in order to make Deep Speech sound as imposing as possible. Some DMs are as simple as describing it as a type of whale song but slightly distorted. You might even say that to our ears it is a series of sounds that are incomprehensible and really difficult to recognize.

In addition, Deep Speech has not got a defined sound does actually make it a bit annoying. But it provides DMs the most powerful weapon they could actually want, and that is freedom. You get the chance to create Deep Speech a language that is memorable and unique to your campaign.

So you could have it whatever you wanted. Just do not make it too disturbing in the game. Furthermore, you probably want your gamers to come back for the next session in the game.

When Will Deep Speech Be Useful In DnD?

Rarely, the majority of Deep Speech speakers dwelling on the Material Plane actually live in the Underdark, and the Far Realm is an uncommon selection of adventure setting.

If your campaign hardly ever takes you into the Underdark or to the Far Realm, you may not encounter speakers of Deep Speech in the game.

However, if you spend most of the campaign exploring Underdark, other in-game languages like Undercommon are far more widely spoken.

Deep Speech Speakers are typically strong, evil creatures. Therefore, any Deep Speech speakers you meet in the game are likely to be major bad guys in the campaign.

No matter how rare they may be, Deep Speech speakers you encounter will likely be in-game characters worth speaking to.

Some of these in-game creatures, like Aboleths, also primarily speak Deep Speech, so Deep Speech might be the only way to actually communicate with them.

But generally, in any campaign where Deep Speech would be helpful, Undercommon will probably be more effective in the game.


Deep Speech is just one of the various languages in Dnd, but it is up there for the strangest. It is something that can be difficult to fit into a campaign, mostly before gamers encounter very strong opponents.

But if implemented correctly, it can create certain moments very memorably in the game. All in all, it is actually a fascinating language.

But if you decide to pick it up for your in-game character, remember that it could take a while for you to use it. Also, remember that deciding to learn Deep Speech is not a simple task in the game.
