The word "wrizzle" is not a commonly used word, but it can be phonetically spelled out as /ˈrɪz(ə)l/. The "wr" in the beginning of the word is silent, hence not phonetically represented in the transcription. The "iz" in the middle is pronounced similarly to the "is" in "this." The "z(ə)l" at the end is pronounced like "zuhl," where the "(ə)" represents a schwa sound, making the pronunciation of the whole word as "riz-uhl."
