This audio tutorial describes how to label graphics using talkback including:

• How to add a label,
• How to edit a label,
• Mli>What happens to unlabeled controls that aren't graphic controls,
• How to export graphics files.

You can also, find a written tutorial here.

I'm not much of a talker, despite some years of success as an AT instructer doing professional workshops and recording notes for students. Still, I hope you find the effort useful and entertaining.

Enjoy
