Using MAC Applications with Voiceover (Tiger Edition)

Writen by,

What is Voiceover?

For those with vision disabilities, Tiger includes Voiceover, a built-in screen reader that provides keyboard control of the computer, enhanced screen magnification options, and spoken English descriptions of whatís on the screen. Voiceover enables many users with special needs to work collaboratively with other Mac users and use a Macintosh without assistance.
Voiceover is intended to provide those who are blind, have low vision, or learning difficulties the ability to use a Macintosh. Itís perfect for those who have never used a computer or screen reader before, for those who are new to Macintosh and for those using screen readers on Mac OS 9 and want to take advantage of all Mac OS X has to offer. With Voiceover, youíll be able to create and edit word processing documents, send email and browse the world wide web, even play chess!
Voiceover reads aloud the contents of documents speaks a description of your workspace and the activities taking place on your computer. Tiger includes over 20 unique synthesized voices and you can adjust the rate, pitch and volume of each voice individually. Several voices such as Vicki, Bruce and Fred are also optimized to speak extremely fast so you listen to documents at your own speed. You can also assign different voices to speak at different times. So for example, one will speak the menus while another speaks the content of a document. Thereís also a pronunciation dictionary so Voiceover will speak names and phrases the way you prefer. When typing, you can set Voiceover to speak every character or only complete words.

Setting up Voiceover
Note: Voiceover keys = Control-Option and will be denoted by the short form VO Keys.

Global Settings
Global settings effect Voiceover's performance throughout the entire operating system and are not specific to a particular application.
The following settings will insure that Voiceover performs correctly.
Activate the Voiceover utility by pressing VO Keys f8.
This is a multipage dialog box that offers a wide variety of customization options.
The navigation tab is extremely important and will allow a user to configure how the Keyboard focus, Voiceover cursor and mouse pointer follow each other. Note: while navigating with Voiceover the VO Keys (control-option) must be held down. Alternatively they may be locked by pressing VO Keys-Semicolon.
While holding the VO Keys down press the right arrow until navigation is heard. Press the spacebar to select this tab. Press the right arrow to move to the first item which is a heading called General Navigation.
The following settings should be checked.
Voiceover cursor moves to newly loaded web-page, Group items in web pages, navigate images and only navigate images with a description.
Items can be checked or unchecked by using VO Keys along with the left and right arrows to find the item and pressing VO Keys-spacebar to check or uncheck the item. Voiceover will speak the state of the Item.
Cursor tracking is the next heading under the navigation tab. The following items should be checked.
Voiceover cursor tracks keyboard focus, Keyboard focus tracks Voiceover cursor, Mouse cursor tracks Voiceover cursor. Note that Voiceover cursor tracks mouse cursor is not checked. This is a safety precaution. Should a blind user accidentally bump the mouse or
the track pad on the notebook computer the Voiceover cursor's position would change making it difficult to stay focused on a particular item.
Under the section entitled Text Selection Tracking on the general tab all items should be checked.
There are many other settings that can be customized to suit the user however the settings outlined in this document are essential for optimizing Voiceover. Also note that although some of the settings mentioned dealt with web pages they have been included in the global list.

Application specific settings

Note: Voiceover keys = Control-Option and will be denoted by the short form VO Keys.


Unlike global settings application specific settings effect a particular application and do not effect the entire opperating system.
The settings that will be discussed are for Safari, Text Edit and Calculator.

On the advanced page of the dialog under the section Universal Access check the box that says Press tab to highlight each item on a web page. This will allow the tab key to move through the links on the page and Option-Tab to move through controls such as edit fields, check boxes and push buttons.
Hiding the Bookmarks bar can make a Voiceover users experience browsing the internet much easier. The Bookmark bar contains a variety of websites a user can easily go to by the click of a mouse or the press of the Voiceover keys. However, since there are many bookmarks on the bar it takes a while to find the actual HTML content. Hiding this bar enables the Voiceover user to access the content quickly and easily. A Voiceover user can access bookmarks from the menubar.
The bookmarks bar can be found under the view menu and can be hidden in the following two ways.
1. Press Command-Shift-b. This command is a toggle that allows the bar to be hidden or shown.

This is a multipage dialog containing two pages. The first page will be highlighted and is called New Document. ‹nder the options section Show Ruler should be unchecked. The reason for this is it allows VoiceOVer to track better wehn reading the text of a document. If the ruler is checked the Voiceover cursor will sometimes get stuck on the ruler and read it's information rather then the document.
