Speech recognition done some time ago, because time is tight, so the Internet to find some code to spend, and found some very complex, and now want to use speech recognition to the Unity project in the past, so they sort out a bit found In fact, Microsoft has given us a good package library. The following is the use of Microsoft's Speech SDK5.1, the database uses MySQL database (MySQL database just contacted yesterday, but it feels good so than SQL Server to be easy to use, speed is not fast, think the general project, then MySQL will be able to cope a)
Interface according to their own design hobby ^ _ ^
