No it takes the titles from the ncx or nav titles for that file. All epubs needs a valid ncx or nav but not all epubs properly use heading tags (unfortunately). Have you built an ncx or nav? Access Aide is meant to be run on almost finished epubs to add accessibility features.

Try using Sigil tools to create or update the table of contents (TOC) before running Access Aide and it will use your headings tags to build the ncx, nav.
