This is Mute Player Voice by KhaoMaat, but simply converted into an ESL and made available on Xbox and PS4. Compatible with everything.
Unlike other silent protagonist mods, this one directly sets the volume of player's sounds to be muted via plugin. This way it doesn't need a million patches for every new mod that adds player dialogue, and you won't have to deal with compatibility headaches of your mute player suddenly talking during modded content or in Creation DLCs. No sound files required, either, for a tiny file size. It just works!
The only minor quirks I've ever found with this method:
During one of the Automatron quests, a robot that you carry in your inventory would also be muted since it's using the same way sound plays when the player speaks. However, that quest is fully subtitled, of course. So you can still read that robot's dialogue subtitles.
You still speak when finding Railroad hints/solving the entry puzzle.
If you don't care about ESLs, then you're welcome to keep using the original mod.
Install & Uninstall
To install, drop the plugin into the data folder to do so manually, or install it with your mod manager like usual.
To uninstall, you can delete it from your data folder if you installed it manually, or delete it from your mod manager.
Safe to add/remove for your save files at any time.
