The pronunciation of Zhuo's name is "Zhu-oh." This is the most common and accurate way to pronounce the name in English. The first syllable, "Zhu," is pronounced with a "Z" sound followed by a "u" as in "zoo," and the second syllable, "oh," is pronounced as in "oh" without the "r" sound. This pronunciation is based on the Mandarin Chinese pronunciation of the character "卓" (Zhuó), which is the most common character used for the surname Zhuo.

The reason for this pronunciation is rooted in the phonetic rules of Mandarin Chinese and the way English speakers typically adapt Chinese names. According to the Chinese Pinyin system, which is the official method of transcribing Chinese characters into the Latin alphabet, the character "卓" is pronounced "Zhuó." When adapting this name to English, the "ó" sound is approximated to "oh" because there is no equivalent "ó" sound in English. Additionally, the "Z" sound is retained from the Mandarin pronunciation, making "Zhu-oh" the most accurate and widely accepted English pronunciation.

Data supporting this pronunciation can be found in various sources, including dictionaries and language learning materials. For instance, the "New Practical Chinese-English Dictionary" by Charles N. Li and Sandra H. Liu lists the pronunciation of "卓" as "Zhuó," and the "Collins Chinese Dictionary" also provides the same pronunciation. Furthermore, language learning platforms and educational resources often use "Zhu-oh" as the standard pronunciation for the name Zhuo in English-speaking contexts. This widespread adoption of the "Zhu-oh" pronunciation underscores its accuracy and acceptability among English speakers.
