1. The original reporter found  a defcustom, likely because his
   emacspeak is out-dated; there used to be a defcuston -- so see my
   first tip re always first checking version.
2. Your steps were technically correct otherwise but you started being misled.
3. If you hadn't been misled, you'd likely have read the code in
   emacspeak-speak-line a bit more, rather than   jumping to the
   cross-ref; so tip: if jumping doesn't yield an answer, read the code
   a bit more.
4. I'll cite the code block to read below -- see if you spot the
   intended  solution that is already built-in.

   So read the complete cond form below -- not just one of its arms.
   
   (cond
             ((or                       ;speakable
               selective-display
               (< l ems--speak-max-line)
               (get-text-property start 'speak-line))
              t)
             (t
              (when (y-or-n-p "use Visual Lines")
                (call-interactively #'visual-line-mode))
              (unless visual-line-mode
                (put-text-property start end 'start-line t)
                (setq ems--speak-max-line (* 2 l)))
              t))
