There is no association between those links, so they are obviously a bunch of random links (which all have meaning of course, but don't have a "group" as such). Visually, thats just a bunch of random links too (are you getting the connection? Browsers and screenreaders are the same in this regard).

Exactly Liam.

If someone with a screenreader needs a title, then people using a standard browser need a title too. If the menu is intuitive enough to figure out for a visual person, then someone with a screenreader will pick it up too.

Therefore, if the menu needs a title to explain it, then it should be visible across all browsers. There is no need for any hidden titles.
