When I used Google voice to make a call, the other side informed me that he could hear his echo. The reason is that I was using my laptop's internal microphone as input and internal audio stereo as output for me, which could send back any sound played out by the internal stereo. So I wonder how to prevent the other side can hear his echo? Thanks!

The simplest solution would be to use headphones. –  iglvzx Mar 28 '12 at 21:40
    
Use directional microphone or headphones? –  Lazy Badger Mar 28 '12 at 21:48
    
Thanks, @iglvzx and @Lazy! I will try to buy a headphone. Is there any simple way to mute the microphone on my side when the other is speaking? I know I can click the microphone button of google talk, but just for quicker switch between mute and unmute, I wonder if there is a quicker way, such as a shortcut key or something? –  Tim Mar 28 '12 at 21:56

I had the same problem. I fixed it by turning on echo cancellation on the device. I am using Windows 7. It is under the properties setting on the microphone. I have made two phone calls now and the echo on the other end is gone. They no longer here their voice echo. I hope this helps.
