A tool that you can use to add voice narration to slides that you display online. instead of recording your voice you type what you want the narrator to say. Where you might type "speakers notes" in other slide programs, in Hello Slide you type out the narration. Hello Slide creates the audio and narrates your slides for you. While the voice is slightly robotic, it is much much better than most text to speech services.
