Voice input computer systems (or speech recognition systems) learn how a particular user pronounces words and uses information about these speech patterns to guess what words are being spoken. Voice input systems are useful for the following problems: Trouble physically using the keyboard - Voice input systems can allow a person to operate a computer without using a keyboard or mouse. This can help people who are not able to use their hands at all, as well as others who can use their hands but are limited by speed, fatigue, or pain (e.g., carpal tunnel syndrome, one-handed keyboarders). Trouble creating text - Voice input systems can help a person, who has difficulty spelling words, create text. This can be particularly useful for some people with learning disabilities. However, the person's reading abilities need to be strong enough to recognize when the computer displays the wrong word.
