The correct spelling of the phrase "bring knees" is /brɪŋ ni:z/. The word "bring" is spelled with a "g" at the end, indicating the voiced velar plosive /g/ sound. The word "knees" is spelled with a double "e" at the end to indicate the long vowel sound /i:/, followed by the letter "s" to denote the voiced alveolar fricative /z/ sound. It's important to pay attention to the spelling of words to effectively communicate in written English.
