I've been using TTS (Text-to-speech) software recently to have the computer read back my material to me. I find it works quite well to catch errors and to hear if the flow of the writing is sound or not. Reading out loud to myself helps as well, but somehow I feel TTS is a bit better because it's completely agnostic to how your text should be read. Anyone else ever used text-to-speech software to proof "hear" their writing? If so, which software did you use?
