Where the stress falls. “physiological” has 6 syllables, and the transcription /ˌfɪz.i.əˈlɒd͡ʒ.i.kəl/ puts the primary stress mark (ˈ) before the fourth one — so the fourth syllable is the longest and loudest. The others are said quickly and lightly.

An unstressed vowel reduces to schwa. /ˌfɪz.i.əˈlɒd͡ʒ.i.kəl/ contains a schwa /ə/ — the short, neutral “uh” that English unstressed syllables collapse into. Saying /ə/ there, instead of the vowel the spelling suggests, is most of what makes the word sound native.
