The spelling of "de tracts" can be confusing, as it looks like it should be pronounced "dee tracts." However, the correct pronunciation is "dih traks." This is because the "e" after the "d" indicates a schwa sound, which is an unstressed and neutral vowel sound. IPA phonetic transcription for "de tracts" is /də ˈtræks/. It's important to pay attention to these subtle vowel sounds when spelling and pronouncing words correctly.
