a question

[weihong rong]

I am considering using Labview to build an application soft to analyze
voice, using the
microphone of the computer as input, is it possible?

Thank you in advance for your answer.

It depends on what "analyze" means.
In LV 6 you have some helpful functions for managing audio I/O (located in Functions > Graphic & Sound > Sound palette).
If you are thinking on something complex (like speech recognition), check this post [http://exchange.ni.com/servlet/ProcessRequest?RHIVEID=101&RPAGEID=135&HOID=506500000008000000F8350000&UCATEGORY_0=_49_%24_6_&UCATEGORY_S=0]
Hope this helps.

You may want to take a look at LabVIEW Signal Processing and LabVIEW Sound and Vibration toolsets.
