I am little confused over this matter; the teacher has stated that no English word can start with two stressed syllables and that you understand a syllable is stressed when it's not reduced to a schwa and when it is therefore a full vowel. For words like biology (/baɪˈɒl.ə.dʒi/), it seems that the PRICE vowel /aɪ/ is followed by the LOT vowel /ɒ/. It makes 2 full vowels followed by each other and contradicts the first information of the teacher.
Is there something I am missing?
The teacher considers aɪ an unstressed syllable.
The cambridge dictionary also considers it as being unstressed: /baɪˈɒl.ə.dʒi/ and not /ˌbaɪˈɒl.ə.dʒi/.
