I would still like to hear from Larian devs if the issue with voiced protagonist indeed is of financial nature, and whether it would really cut down on the content in the game. I don't want to make assumptions on their behalf. And ultimately, I am a consumer, not their employee or their representative. I can only ask for content, and I can understand if they clearly state it isn't possible for technical or financial reasons.
As for the immersion aspect:
The lines are already there in the dialogue options. What you choose is what you get. I expect the protagonist to have their own way of expressing themselves, I don't want them to be entirely my (mute) puppet. I don't go control-freak on my avatars, I expect the game to do things outside my control, because it WILL do it one way or the other. This isn't table top where you yourself can verbally playact and talk to your DM, and it can never be, the concept is different.
Voice actors have done a tremendous job in this game and I trust they would follow through with the atmosphere in the dialogue. I am not actually projecting myself into my character, I am more like their guide into the game's story. And that is why their muteness bothers me and why to me they feel incomplete.
I see I'm in the minority here. I see that the preferences of the majority are the main reason why the protagonist is mute. But I still wish to have my own preference on offer, and I would pay for this addition in the form of DLC or something similar, if necessary. If not... Well. At least I asked.
