It should be: "psa" - /psa/ - normally one syllable long word "ci" - /ći/ - ć letter sound and then i "ekran" - /EK-ran/ - accent on the second from last sillable, here it's the first one "radio" - /RA-dio/ - accent on the second from last sillable, here it's the first one, it can be /Ra-dyo/ or /Ra-dio/ with soft d (I've heard both versions, so I'm not sure which one is correct, but I think both, because both are used).
