The correct spelling of the word "more intermitted" is actually "more intermittent." According to the International Phonetic Alphabet (IPA), the pronunciation of "intermittent" is /ˌɪntərˈmɪtənt/. The "t" in "intermittent" is pronounced, meaning that the past tense form "intermitted" ends with a double consonant "tt." However, when we add the comparative form "more" in front of it, we don't double the "t" because it is not the end of the word. Therefore, the correct spelling is "more intermittent."
