Alternative presentation of content

We have a problem developing a Lectora-based presentation in which on-screen information is not the same as what is read in an audio track on the page. The transcripts for each audio do not therefore deliver equivalent information since they do not include the on-screen text. Changing either the on-screen text or the audio (and transcript) is not possible, alas.

So…

One idea we had was to write a text-only equivalent version for each slide's screen+audio; we would make this equivalent presentation available through an "accessible version" icon (control) on each page; the icon is initially hidden but a sight-impaired user will have been told to find the control by tabbing to it; the icon/control becomes active (and visible) when given focus; when clicked it causes the screen reader to read the equivalent content. For users who may not have a screen reader but who need this alternative we can display the text-only version as an overlay.

Would this be considered an alternative presentation of content?

Thanks for your input!
