I checked the official DVD, and the subtitles for that alien guy read:
“Everything has been arranged
precisely as you have requested…”
“most illustrious Count Dooku.”
and then
“I trust you will find
what you seek.”
In said DVD the subtitles play automatically but are not hardcoded. Dunno if you’d want to include them, but it does make clear that Dooku is scouting out an assassin.
