Hello :), The title kind of says it all, but i was just wondering if there was maybe a piece of software or something that would enable me to do this.. main reason being, i would like to leave speech recognition on whilst listening to music so that it doesnt constantly try to dictate my music :P

To do what you want you would be looking at some very, very expensive audio filters. The kind that are used in military communications and top rank recording studios. Software alone wont do it.

Speak recognition is not that good at the best of times and any extraneous noise, even normal background noise, is going to have an effect.

Research is being done but I don't think the software you seek is anywhere near ready for home use. At present the best you can do would be to physically isolate the music from the microphone, such as by using headphones.

When your speech recognition software, or any other program that can use a mic, is not running, go into your sound mixer settings and make sure the Mic is MUTED there. It's supposed to be muted there. If that's not muted, the Mic is picking up sound all the time Windows is running. When you use a program that can use a Mic, it's auto un-muted; when you quit the program that can use a Mic, it's auto muted again.
If you're not sure how to access the sound mixer settings...

You could try
- placing something over the voice recognition's headset's Mic on the side towards the computer so that it doesn't pick up the music so easily. E.g. a piece of thin but not flimsy hard or flexible plastic.
- turn down the Mic volume in the speech recognition program's settings to the point where the speech recognition still works but it isn't picking up the music at all or as much.
- turn down the music's volume while you're using the speech recognition program.

Some Sound Cards Can Filter The Sound From It's Outputs Away From Inputs I Have A Cheap Motherboard With Onbaord Sound And The Soundcard Is A Realtek Piece Of Rubbish But My Bro Want To Have His Speakers On nd Talk Over Mic Without Feedback Like I Have But It Is A Bloody Pain Searchin The Net To Find Software Or A Soundcard That Does What My Cheap Soundcard Does. Surely Somewhere Out There I Can Just DL A Program To Do This.. My Lattest Thought Is To See If I Can Get A PCI Card That's The Same As My Onboard Realtek Do This You See.. But It Would Be A Shame To Remove His Creative X-Fi Titanium Fatality.
