Change Speakers slug

Hi!
How could I change the speakers taxonomy slug and name?
I found this code for changing the podcast archive slug but I couldn’t do the same for speakers:

add_filter( 'ssp_archive_slug', 'ssp_modify_podcast_archive_slug' );
function ssp_modify_podcast_archive_slug ( $slug ) {
  return 'new-slug';
}

Thanks in advance!
