Most people are aware that between the spoken and written language is an essential difference. Therefore, they also agree that the (still) read a text not meaningful for this is the same text as finally spoken aloud act as a speech or talk. Take just one example, a drama by Goethe can whether the word choice, sentence structure and melody ecstasize reading, but you would never talk to his friend this way. From the above is quite clear that only an acoustic speech preparing a professional requirement to be answered. Although these facts to try a phenomenon commonly accepted and known quite a few, prepare your speech or presentation in writing and then (often literally!) The public be expected as an oral presentation.
Actually it should not surprise that this project fails regularly. You yourself know the peculiar effect of such "lectures" and probably painful too well. Bfpl pursues this goal as well. The solution for those who are like writing prepared, there is now a fabulous resort. With a completely new, simple software you can read all the written documents are available no matter what format it. With a single click you hear your speech or presentation (voiced perfectly by a third person) rather than their own silent speech read only as (to) readers. The crucial advantage: they are already in preparation in the listener role. Only in this way, they can not accurately assess the impact of their speech in the form in which it will ultimately contribute also to the audience. Connect their eyes and listen to your own (written) words, you'll be amazed how big the difference between an acoustic speech preparation to the Self-reading is. If you with improving your speech really serious about this, you can look at that possibility, even a demo video.
