Show, Describe, Share: talking presentations in three easy steps

It is difficult to replace you, when it comes to deliver your presentations. However there are times when your presentation must do without your presence, for instance if you want to share your presentation online.

The alternatives are many. There are well known places where you can publish your presentation as a silent collection of pictures without comment. Or you may take up a microphone and tell your story with your own voice while capturing your presentation as a video.

A third alternatives is using text-to-speech to deliver your presentation, and make it into a video. Text-to-speech has made huge progresses in the last years, now offering several high quality voices with different characters. However the obvious disadvantage of using text-to-speech is that it is not you speaking and that text-to-speech might ruin your opening joke. On the other hand typing a description is so much easier and much faster than speaking into a microphone. Not to mention that if few days after publishing your presentation you decide to do a slight change to the wording, all you need to do is to quickly edit a text, as opposed as to redo the whole recording.

The show, describe and share principle mentioned in the title of this article consist then in using your images to show your message, using your descriptions to deliver your narration (via text-to-speech), and using the resulting video to share your presentation with your audience.

To publish a presentation with text-to-speech by following the show, describe and share principle, you can go to, a service launched recently and still available as open and free beta, and follow the three steps below:

1) Show: Upload your pictures to If your presentation was made with powerpoint, you can use "save as PNG" (or JPG)  to save the presentation as a collection of images, then import the images to

2) Describe: type a text comment for each picture, as you would do when in front of your audience.

3) Share: Texts are converted to audio, and picture and audio are combined together in a YouTube video, ready to be shared with your audience or published on your website.
