A free mod for Mount & Blade II: Bannerlord, by Xorberax.
Xorberax's Voice-Over Framework is a mod/framework for Mount and Blade II. This is a work-in-progress and is not meant for players yet. It is currently aimed at voice actors. If you're interested in contributing, please join my Discord server linked below in yellow.
If you're using the mod/framework and you want to make a voice recording, you need to first save your recording to the "data" folder. You need to specify the file name, and it'll play when you encounter the dialog again. You need to do this for every recording you make. You can record a voice-over and save it in .ogg format with the file name specified. You can save it to the "data" folder.
