Where is the stress on tacluso? Is it not on the penult? The voice sounds like tácluso...
remember that this is a bot. From Wiktionary:
(North Wales) IPA(key): /taˈklɨ̞sɔ/ (South Wales) IPA(key): /taˈklɪsɔ/
(The ' in the IPA comes just before the stress), so to answer your question, it IS on the penultimate: taclúso.
As a bot, she's normally spot on, but this one confused me... Thanks for the IPA!
