fvtt-module-polyglot VS warpgate

However the module Polyglot will give you some control over it, and their wiki has info on how to work with the languages

fvtt-module-polyglot - Talk to others using a language you can speak and scrambles text you can't understand, into several fantasy scripts.

Polyglot - Allows players to use their tokens to speak in different languages. Only other players with that same language can understand what is being said.

Polyglot - lets you send messages in lots of 5e languages. Any character who understands that language can see the message translated, and others just the glyphs of the language.

Polyglot: Speak as different languages

Polyglot

I have been wanting something similar that works with Polyglot. The module itself converts chat messages to runes if your character doesn't know the language being spoken. I would love something that similarly scrambled voice chat if the character didn't speak the language.

warpgate - Warp Gate is a system-agnostic library module for Foundry VTT that provides a growing number of API functions to make programmatically spawning tokens and modifying those tokens easier for players and GMs alike. Usable both directly via client Macros and as a dependency for other modules to build and expand upon.

Yup. Warp gate can do this with some item macro magic. https://github.com/trioderegion/warpgate … this would involve mutations, just FYI.

Warp Gate - This is a set of functions that greatly reduce the amount of code needed to do something.

Sounds like Warpgate could be the module to use for this, see https://github.com/trioderegion/warpgate/wiki/Mutating-Goblin for a possible example of how to do what you're after.
