HelloSlide - Bring your slides to life | Web 2.0 for Education | Scoop.it

Simply type the speech for each slide, instead of recording it, and HelloSlide automagically generates the audio.

It gives more exposure to your presentations, making them searchable, editable, and available in 20 different languages.

There is a free version available which limits the  number of presentations you may do per month.

This was very easy to use and the pronunciation is quite good.
