שמע משותף

AITA for refusing to share my cloned voice? I built a small TTS tool and trained it on my voice for a side project. My coworker heard it and now wants the model so he can “use my voice” in his videos. I said no—it feels personal and a bit creepy. He says I’m overreacting and it’s just tech. Now the team thinks I’m being difficult. AITA?
