OK Raman, try this 100% guaranteed untested version:

(defvar emacspeak--last-docs nil
  "Last docs considered in `emacspeak-speak-eldoc'.")

(defun emacspeak-speak-eldoc (docs interactive)
  "Speak eldoc.  Intended for `eldoc-display-functions'."
  (with-current-buffer (get-buffer-create " *emacspeak-eldoc*")
    (erase-buffer)
    (insert (mapconcat #'car docs "\n"))
    (unless (equal docs emacspeak--last-docs)
      (emacspeak-auditory-icon 'doc))
    (when interactive (dtk-speak (buffer-string))))
  (setq emacspeak--last-docs docs))


The main difference to your version is that it doesn't rely on
eldoc-display-in-doc-buffer being also a member of
`eldoc-display-functions'.  Not only is this more future-proof
it also means that that other eminently visual display could,
if you so wanted, be completely discarded in favor or the auditory
one (if you or the user so wishes).
