Hello Slide is a web tool that lets users add speech to each slide in an online presentation. The user simply types the speech for each slide, instead of recording it, and then Hello Slide automagically generates the audio (in a pretty bearable computer-generated voice). This would be a great assist to students that need some help with reading as well as those who would benefit from translation service, as the audio can be produced automatically in 20 different languages. A really great web tool for sharing presentations.
