Provided is a semiconductor device including a package having a hollow portion, which can meet the need of reduction in size and thickness. The PDA further includes a second display controller for converting the image frame data set stored in the memory into a second image signal and passing it to the image output port so that an external image display device connected to the image output port can display the image, and a central processing unit for executing programs and controlling the operations of the PDA. The invention also concerns a device for implementing said method. It derives selection information and uses it to select the best speech recognizer and its results and returns those results back to the application.
