I read the article and I feel unseen, invisible. It is yet another accessibility initiative that assumes users fit into the 'blind' or 'not blind' categories. There's never a mention of people needing speech recognition or any other physical mobility aid. Keyboard shortcuts are not enough.

I should be able to navigate a webpage completely by speech. The actual speech UI would take some thinking. You want both absolute by name and relative references, as in "follow that link," "third link back," "follow threads", and " follow new," as a bare minimum.
