A slidetalk video is a video made by playing a Powerpoint file or a sequence of still pictures (slides) each with a description that is read out aloud by a text-to-speech engine. Slidetalk videos are a great way to publish and share your presentations including your own comment to the slides, but without the hassle of needing to speak the comments yourself into a microphone or hire a voice talent.
