2. Case introduction

Step 1: First enter the Xunfei open platform to register an account, then create an application, name it according to your own ideas, and an APPID will be generated. For details, refer to how UE4 accesses the voice recognition of iFLYTEK_ue4 科大信息Flying Speech Recognition_Flying Pig Blog-CSDN Blog

Step 2: Download iFLYTEK’s Speech-to-Text SDK, open AndriodStudio and run
