To enable closed captions, start the orientation presentation in Chrome. Then, find the audio control icon on the top right of the chrome browser.

Ensure the Live Caption option is enabled. If the option is enabled, but no captions are present, toggle it off, then on again.

If the audio is not automatically starting, please check to see if enable auto play needs to be turned on. An exclamation point will appear next to the slide controls in the bottom left if this option is not enabled. To turn it on, hover over the exclamation point and select 'enable'.
