Voice recognition systems have been on the market since the 1980’s. IBM and Dragon Systems were among the first manufacturers and are still leaders in this field.

The systems were not primarily developed for people with disabilities, but for them the technical development was especially welcome. Various versions of voice recognition systems are now specifically optimized for disabled users and thus meet the requirements for accessibility.

High degree of recognition accuracy

Speech recognition software is now so powerful that dictated texts are detected with up to 99% accuracy. Through the use of high-quality microphones and associated dictionary information, the recognition accuracy is so high that even sophisticated error-free texts can be dictated, even if the pronunciation is somewhat unclear.

How does it work?

Voice recognition software for PCs is controlled by the user’s voice. With most programs after initial installation, the voice and pronunciation of each user must be set up. This is done by reading short passages of text; this helps the program to connect the vocabulary stored in its database with the pronunciation of the individual user. In improved, most recent versions of voice recognition software this step is no longer necessary.

What the mouse can do, so can the voice

When the installation is successfully completed, the voice recognition software functions easily and effectively. Users speak into a microphone, and the computer executes the commands, writes, corrects, formats, mouse movements are as well as control commands also possible. In short, everything you can do with a keyboard or a mouse can also be done with the voice. The dictation, editing and control will work in all current applications, like Microsoft Word, Outlook Express, Internet Explorer, etc.
