With voice communications you can dial up a friend at any telephone, talk for hours, teleconference, and receive voice messages, all over the Internet. In addition to providing all the traditional benefits of telephone communications, voice communication over the Internet may save you money over heavy long-distance telephone bills. There are many software applications that exist which allow you to talk online with a second party for free. There are two types of voice communication: half duplex and full duplex. Half duplex allows one person to speak at a time, like talking on a walkie-talkie, while full duplex allows dual direction conversation. Clarity in speaking and hearing depend on which type you select. In order to achieve voice communication over the Internet, you'll need to obtain some essential software programs. On your computer, you need a Web browser, the required quality of which might be determined by your chosen voice communications vendor, in order to access the Internet. While your browser will get you onto the Web, you'll probably also need specific voice communications software, which many voice communications providers offer for free on their Web sites. With the right voice communications software downloaded and installed, you'll probably need a sound card with speakers and a microphone installed and configured, as well as the software needed to make these devices work.
