Speech recognition systems are on the market since the 80ies. IBM and Dragon Systems were the first producers and are still leading in this field. These systems were not devised for people with disabilities in the first place but the technical development is particularly useful for peo-ple with disabilities. Today, different speech recognition systems are specially optimized for a disability-friendly use, and meet the accessibility standards. Speech rec-ognition software has become so efficient that dictated texts are identified correctly up to 99%.
With high-quality microphones and suitable dictionary files, the recognition accuracy is so high that even diffi-cult texts – even with clipped speech – can be generated correctly. Speech recognition software for PCs is con-trolled speaker-independently. In the most programs, voice and pronunciation of the user has to be adjusted first after installation. This is done through reading out short texts, which helps the program to connect the program-resident vocabulary with the individual pro-nunciation of the user. In newer and further developed versions, this step is not necessary anymore. If the in-stallation is done, the speech recognition software is easy to use and effective. The user speaks into a micro-phone and the computer executes the commands, writes, corrects and formats. Mouse movements and control commands are also possible through speech. Every command that can be given by keyboard or mouse can also be given by speech. Dictating, editing and con-trolling works within all standard applications such as Microsoft Word, Outlook Express, or Internet Explorer.
