Audio messages on Zwift Workouts

Hello,

How are you?

I am a visually impaired Zwift user, and I am trying to make Zwift workouts more amenable by adding audio messages. I have been on a couple of group workouts where there has been an instruction voice at the start, so I know it is possible.
I am looking at the ‘gameplayevent’ in the ZWO schema. Can the GPE_AUDIO attribute be used to trigger this audio messages? Do you have an example of using audio message in a ZWO file that you might point me towards?

If successful, I hope to post up some visually impaired accessible versions of some of the common workouts such as FTP tests.

Any help much appreciated.

I look forward to hearing from you.

Stay safe and happy Zwifting,

Guy
