Re: Programmatically binding an audio file with its text equivalent

Adding tabindex="0" to the audio tag can help. VoiceOver reads the
aria-title this way. I'm not in a place where I can test the other screen
readers at the moment, but I'm cautiously optimistic this will help.

<audio tabindex="0"... etc.
