"从芯" is pronounced as "Cóngxīn" in pinyin. Here’s how to pronounce it:
- "Cóng" starts with a "c" sound, which is similar to the "ts" in "cats," followed by the "óng" sound, which is similar to the "ong" in "long" but with a second tone that starts low and rises.
- "Xīn" begins with an "x" sound, which is similar to the "sh" in "she" but with a slightly more forward placement of the tongue, followed by the "īn" sound, which is similar to the "in" in "bin" but with a first tone that is high and level.
When pronouncing "Cóngxīn" together, it should sound roughly like "tsong sheen," with attention to the specific tonal inflections of Mandarin Chinese.
