In the Volume Control window, click and drag the bar in the Volume Control column, and slide it up or down to increase or decrease the volume. Note: Because there are several noise sources, such as the fan, hard disk and speakers in the computer, the speakers will scream when the volume is too high. This is caused by the internal speakers' positive feedbacks and can be eliminated by decreasing the volume. When you perform voice recognition tasks, we recommend you use external microphones, because the inner noise has a severe effect on the internal microphones. 36
