Tazti is a completely free download for Windows, a lighter-weight alternative to software like Dragon NaturallySpeaking. Tazti doesn’t handle full-text dictation; it’s just designed to work as a control interface. As demonstrated in their video, Tazti responds to voice commands, with a custom interface geared toward popular tasks like pausing iTunes, navigating Facebook, and running web searches. Neat. The caveat, of course: Speech recognition is not a perfect science yet. The longer you train the software, and the more silent your surroundings when you use it, the better it’ll work.
