Kim Jo Han comments on former vocal students Girls' Generation's Taeyeon and Jessica

Veteran R&B singer Kim Jo Han revealed what it was like to train Girls' Generation's Taeyeon and Jessica as their vocal coach.

On the November 12th broadcast of MBC FM4U's 'Kim Shin Young's Noon Song of Hope', Kim Jo Han revealed, "I taught Taeyeon and Jessica. They were both outstanding students."

DJ Kim Shin Young asked, "Between Taeyeon and Jessica, who did you have to help a little more?" Kim Jo Han responded that both idols were talented as expected, but they each had their own approach, saying, "Their styles are totally different... Taeyeon always did well. When Jessica first came in, she had a small sound. I think she was shy... But in a few months, Jessica improved a lot, so I was impressed."
