The Deep Speech was the language for the Mind flayers, beholders and also it was the language for the aberrations and for an alien form of communication too those who are originating in the Far Realm. It didn’t have any specific script until the mortals written in the Espruar script. So this Espruar was acted like the d&d deep speech translator.
But what is the deep speech when they didn’t get this Espruar script was, the gnomish pictograph by using this d&d language they used to convey properly their language by the esoteric symbology. This was extremely complex and highly contextual language and it was reliant heavily on more than not only just on sound but the tone and inflection too.
Nearly it uses all of its organs including body language such as smells, trilling, gurgling, and a whole manner of unpleasantries which most of the mortals struggle with performing.
