Why can the Japanese keep their voices clamped all the time?

The reason why the Japanese can keep their voices clamped is that they look cute when they speak with their voices. Simply put, it's a voice that sounds delicate and pretends to be a lovely girl. Characterized by very artificial, very artificial, quite artificial. Most Japanese people do this, including corporate HR. Unlike girls who can switch voices at will, the life of natural selection by sandwiching is like playing a soul game and starting a difficult mode.
