Chapter 6 VoiceOver Utility and Preferences 55

Â Status: This voice lets you know the current state of buttons and other controls. For

example, the status of a checkbox is either “checked” or “unchecked.”

Â Type: This voice identifies the type of item. Some examples are button, slider, scroll

area, and HTML content area.

Â Attributes: This voice speaks the text attributes at the beginning of text with

different attributes than the preceding text. For example, “bold 15 point” or “12 point

Helvetica.”

Â VoiceOver Menu: This voice reads the commands in the VoiceOver menu.

Click the pop-up menu next to each type of information and select the voice you want

to use. If you don’t make a choice, the default voice you chose will speak the

information.

You can practice using your VoiceOver skills to change voice settings in the exercise at

the end of this chapter.

Changing Rate, Pitch, and Volume

Next to each voice pop-up menu are controls to adjust the rate, pitch, and volume of

each voice. Type a new value in the text field or use the incrementors to change the

value.

Adjust the volume to a level that suits you. You can also use the volume controls to add

emphasis or tune out information. For example, you may find it useful to set the

volume higher for content and lower for other information. If there’s information you’d

rather not hear, set the volume to 1, which is the lowest value.

If you want to return all the settings to their default state, click the Reset button. But

remember, this changes almost all of the settings in VoiceOver Utility, not just the pane

you’re in. The only settings that won’t change are entries in the Pronunciation pane.

You can practice using VoiceOver to change the rate, pitch, and volume in the exercise

at the end of this chapter. For information about changing these values temporarily as

you work, see “Changing Rate, Pitch, and Volume Temporarily” on page 25.

Setting Visual Options

It can be difficult for a person not accustomed to using VoiceOver to follow along when

someone else is using it. To help them, VoiceOver provides visual feedback on the

screen.
