Simultaneous Recording Voice Signals and Playing

Hello,

I have been trying the following code for voice recognition and playing but it throws me 'System Error' as...

------------->>> <<<---------------------------

Code: AI = analoginput('winsound');

-----------------------------------------------

Error: Error using ==> analoginput.analoginput at 46 To learn about using data acquisition devices on the win64 platform, see the documentation on the session-based interface.

------------->>> <<<---------------------------

"""PLEASE NOTE: I am using the Computer Microphone as the Audio Input device"""

Although,I got some good references from the following links, but the same error is encountered due to the Session-based Interface for Windows 7(x64) Platforms.
