Output Devices : Sound

Sound can be output through loudspeakers or headphones. On microcomputers you also need to install a sound card to be able to output sound. If you want you can connect the computer to a hi-fi to get louder, better quality sound than you would if you plugged the loudspeakers straight into the computer. The sound produced by microcomputers is now better quality than sound that is recorded on a CD.

Sometimes a computer can read out text that has been entered into it by using a computerised or recorded voice. This type of system is known as speech synthesis.
