Nit: It seems like this first conditional + arm can just disappear since the
body is the same as the arm below.

Unless this is a bug?

     // Replace one substring with another, speak inserted text.
     AppendUtterance(inserted, out_spoken_description);
-  } else if (inserted.size() > 0) {
+  } else if (!inserted.empty()) {
     // Speak inserted text.
     AppendUtterance(inserted, out_spoken_description);
-  } else if (deleted.size() > 0) {
+  } else if (!deleted.empty()) {
     // Speak deleted text.
     AppendUtterance(deleted, out_spoken_description);
   }
