Below is an illustration of exactly what we mean by echo. Typically, they use either the space bar or the CTRL key as the PTT button, but some use one of the Function Keys to do the job. All you do is talk and the software activates it for you automatically. Another solution to this echo problem is to use either a handset or a headset , both of which do not allow the sound to get coupled back into the microphone. We've tested many handsets and headsets and have found a couple that work well with these applications for not a whole lot of money.
Most people seem to prefer using their normal speakers and microphone instead.
This is especially true if you want to have the whole family involved in the conversation since, with the speakers active, everyone hears the other side of the conversation. If you have the volume set low enough or if you place the speakers far enough away from the microphone so the sound won't activate the vox, you can probably get by. It's a fine line at this point. Our solution is a device we call the EchoBuster . Just click on the name to get all the details about it.
