A free mod for Fallout 4, by CDante.
The Player Voice Frequency Slider (PVoFS) is a mod that lets you change the pitch of your voice in-game. It works on all of the audio files in-game. You can use the slider to set the value, or you can use a keyboard to set it.
There are four presets included with the mod: Teenager, Young Adult, Heavy Smoker, and Very Deep. These can be used to adjust the pitch of your voice to match the style of the character.
Let this mod enhance your gaming experience.
