SSE [HELP] Editing a modded followers audio when some is using vanilla voicetype

[HidesFromSun]

Fyi before I begin, I'm very new to creating/editing mods, and only today have I figured out how to add custom dialogue to a follower, but only by removing them from the follower framework by following

tutorial (link)

So I'm trying to create a modification of the Hyrixia mod, by editing the audio files in Audacity so that her voice sounds more 'Daedric'. However I've ran into a problem and I'm a bit stuck.

Not all the audio files that the mod uses are directly in the mods folder. The follower is also using one of the vanilla voice types 'Female Sultry', and uses the femalesultry follower framework, as well as has some dialogue branches somehow attached to that voice type (I think).

So I'm trying to make it so the follower still has all the same dialogue and dialogue options, as well as finding and editing all of the audio files the mod uses, whilst also being careful not to edit the entire FemaleSultry voicetype.

So far I've disconnected the follower from the follower framework in order to give them custom dialogue via the tutorial linked above. I've also edited all of the .fuz files that came with the mod in audacity, but don't know what to do about the others. When I'm loading up the mod, it works up until I can actually recruit the follower. Then the dialogue options that I've added appear (in place of the follower framework), but the additional branches added by the mod (such as change outfit etc.) do not.

Any help with this would be greatly appreciated. As I say, i'm quite new to all of this and am still learning. I've attached an esp of what i've done so far, if you need anything more i'd be glad to provide it
