Part of being a voice aficionado is being able to tell the difference between similar-sounding actors like Matthew Mercer and Troy Baker, or Tipton and Bailey. Or Erica Lindbeck and Erica Mendez who, on top of having similar voices, have the same first name, damn it.
I can to a degree but only distinct voices, like I can recognize Michelle ruff, Troy, Karen Strassman, Jessica Straus, Janice Kawaye, and even Stephanie Sheh XD
