Cold-Call Practice for Sales (SDRs)

I have seen a lot of good content on LinkedIn for SDRs to practice cold call. For example, Mic Drop method is a great one. But after learning the method, cold call requires practice. I have seen some managers role-play with their SDRs but SDRs hate that experience. Some SDRs have role-played with one of their family member. In such cases family members’ knowledge of the market is limited. I am wondering how AI can help in such role-play? If you had an AI role-play tool, what would you like to see in that?
