"Had anyone caught Conan solving a case and using the voice changer?".

The Detective boys have outright caught Conan borrowing people's voices to solve cases. Hattori caught Conan using his own voice and pried his true identity out of him after that. Kaitou Kid also knows about Conan's case solving skills and gadgets. Conan basically stopped pretending about his intelligence and uses all his gadgets in front of the FBI although he keeps his true identity secret. Okiya Subaru caught Conan using Shinichi's voice to talk to Ran. Eisuke figured it out too, but I forget if he found out about all the gadgets. Vermouth knows about Conan's toys, she even used the tranquilizing watch on Conan once. Amuro noticed Conan trying to aim his suspicious watch at Mouri. The Nagano police are getting closer for sure because Conan doesn't hide his intelligence from them, but I don't think they are aware of Conan's gadgets yet.
