I'm trying to make my follower a master alchemy trainer but it doesn't seem to work.
My follower has the same voice as Arcadia (also an alchemy trainer) as I know not all voices support all dialog,
I've got both factions (JobTrainerfation, JobTrainerAlchemyFaction) and a custom class with the training box ticked with Alchemy and 90.
It all runs ok exept when I speek to her she says thing like "There's nothing more I can teach you" as though my alchemy is higher than she can train, which it isn't, it's 20.
Also I thought that her actual alchemy skill needed to be 90+ but the Actors and classes for trainers do not have the appropriate skill level. (50, 75 90)

Any help would be much appriciated thanks.

Check the trainer gold script on the NPC. Make sure you have the gold set to gold001 (IIRC),and the level I think needs to be set to 3 for the highest level.

The gold is set to gold001 and the level is set to 3 but it still doesn't work.

Hmmm. Did you make the changes to the Quest "Dialogue Trainers?"

It works but there's no speech, I copyied the dialogue from Arcadia, who uses the voice type 'FemaleEvenToned' as does my NPC.

The voice for Arcadia's dialogue is:
Data\Sound\Voice\Skyrim.esm\FemaleEvenToned\Dialogue_Tr\OffersTraningT_00085506_1.xwm

The voice for my dialogue (which was copied from Arcadia's) is:
Data\Sound\Voice\Amiliara - Better Follower.esp\FemaleEvenToned\Dialogue_Tr\OffersTrainingT_0000EDE8_1.xwm

Is the anyway to copy the first dialogue to put in my dialogue so the voice will work.
