There doesn't seem to be a commonly recognized word "samfool" in English. However, if this were a word, it could be transcribed using the International Phonetic Alphabet as /sæmfuːl/. The first syllable "sam" would be pronounced with the "æ" vowel sound found in "cat," and the second syllable "fool" would have a long "u" sound as in "spoon." The stress would fall on the second syllable, making the pronunciation "SAM-fool."
