This seems like a very useful app that could go a long way in helping people be safer drivers. I know there are already apps out there that do this (turning speech into text messages and also reading text messages out loud so that you don't need to look at the screen while driving), however there are still a lot of issues with this software. The reviewer seems to be of the opinion that this software works better than the previously available options. I think there should be a function that the program can read out loud what the text says before you send it so that you can be sure that the program accurately recorded what you said.
