How can I solve the problem of not being able to use Azure Speech Service after packaging Unity+C #？
I used Microsoft's voice service in the Unity+c # project, and everything is normal in the Chinese system, whether it is in Unity or the packaged exe. However, in the Japanese system, it is only normal in Unity. As long as I package it as exe, voice recognition will not work properly. I found this error in the log file. Please help me, everyone!
