Speech Recognition help......

Just the other day, I installed Windows Vista. Everything seemed to work just
fine until i tried to set up the speech recognition. I have a Brand new
Microphone Headset, along with a brand new soundcard that the microsoft
website said was compatible with vista, and I also installed the drivers that
the website supported for the sound card, But it still refuses to work. The
microphone doesn't seem to work at all with the system. the system reads it,
but it doesn't work. All the volume setting are raised and the mute buttons
on the computer as well as the mic are unmuted. If anyone has suggestions
PLEASE repost.

Thank you,
Sean
