Hi Sharon,
The Voki won't automatically read the text on the slide, but if you type in the same text into the text -to-speech field in the editor, then the Voki will be able to narrate the text that you have included on your slides. To get to the editor you'll want to click on the icon that looks like a head and shoulders. This will open the Voki editor. Once there, click the button that looks like the letter T on the keyboard. This will open up the text-to-speech field. This is where you can paste text you'd like your Voki to say.
Hope this helps! If you have more questions or need a visual, e-mail me at feedback@voki.com

Best,
Heather

Hi Michael,
Try using Firefox to access your Voki. This may allow audio to work for you.
