Factual error: When Reba is in the darkroom with Dollarhyde she mentions that he speaks very well but avoids fricatives and sibilants. In linguistics sibilants are a form of fricative and Reba would have known that since she'd obviously studied linguistics. The writers likely meant that he just avoids sibilants (to avoid sounding homosexual) but wanted it to sound more technical. Sibilants in English are the 's' in "see", 'sh' in "shout", 'z' in "zoo", and the 's' in "pleasure". Fricatives would include sibilants as well as the 'f' in "fine", 'v' in "vine", 'th' in "that", and 'th' in "thing"
