Dragon NaturallySpeaking
Dragon NaturallySpeaking is an application that allows you to operate a computer by voice command, including transcriptions. I think its a great way to get ideas written down without having to worry about formulating them when typing them out.
You can order a copy of Dragon NaturallySpeaking on the company’s website, or download a torrent through a peer-to-peer sharing site.
You can download Dragon Dictation, an iPhone version of this app for free on iTunes to write text messages or update social media statuses hands-free on your phone. There is also Dragon Search which allows you to verbally search the web, social media, and iTunes.
