The word "bissette" is spelled with two sibilant sounds, which can be confusing for some readers. The first "s" is pronounced as a voiceless alveolar fricative (represented in IPA as /s/) while the second "s" is pronounced as a voiced alveolar fricative (represented in IPA as /z/). This difference in pronunciation can be represented in spelling by using two "s" instead of a single "s". So if you want to spell "bissette" correctly, remember to use two s's to represent both the voiceless and voiced sibilant sounds in the word.
