The spelling of "goes one one" can be a bit confusing. The IPA phonetic transcription for this phrase is /ɡoʊz wʌn wʌn/. Here, the "o" sound in "goes" is pronounced like "oh", while the "u" sound in "one" is pronounced like "uh". The repetition of "one" can make it difficult to distinguish between the two, but the key is to pronounce the first "one" with a more pronounced "w" sound, making it sound like "wun".
