Taeyeon revealed her voice tends to change when singing as a member of Girls' Generation and when she's performing solo.

On the June 30th broadcast of 'Kim Shin Young's Noon Song of Hope', Taeyeon shared, "My voice tends to be different when I am singing solo and when I am singing in Girls' Generation." She explained, "For Girls' Generation, I have to show a bright image, so I tend to sing while smiling, which seems to change my voice. For solo songs, I can sing however I want."
