Change text for Comments? (Hueman)

I have already changed ‘Leave a reply’ and ‘Post comment’ using this code in functions.php:

<?php if ( comments_open() ) { comment_form(array('title_reply'=>'Leave a reply', 'label_submit'=>'Post comment')); } ?>

However I’ve realised I also need to change Comment, Name, Email and Website. Could someone let me know the code to add those in too? Thanks.

(I’m translating into another language, that’s why I’d like to change them.)
