I'm current using Confluence to write a policy, people don't like reading policies and I want to improve the accessibility. There is currently an option to add files and I can upload sound files but it takes you to a different screen to view the file and it looks bulky.

The option to add a speaker / sound icon which when clicked plays a sound file would be great.  

Further to that you could add a sound time elapsed bar so people and rewind rather than listening to the whole sound file / section.

To improve this further, the ability to control the speed at which a sound file is played would be great.
