Assistive Technology Software 1: Speech Software

Speech output or screen reading software provides access to on screen information through synthetic speech. The user navigates the computer via the keyboard and the current focus is announced. By its nature, screen readers give a narrow view of what is on the screen, for example a sighted user may glance at the clock to get the time; a screen reader user would need to know the keystroke to get that information. To fully utilise a screen reader therefore, the user must learn a wide range of operating system and screen reader specific keystrokes.
In general, you get what you pay for with screen readers. However, whether a home user needs the extensibility of a high end screen reader such as JAWS should be questioned when free alternatives exist.
