You mean gay dating software blued? Some people like to find people's pronunciations, and generally don't follow a routine. Their purpose is nothing more than the following:

1. It's too much trouble to find someone to chat with, but you are too lazy to type.

2. It is voice control. I want to induce others to speak in this way and find a little brother with a nice voice.

I think I have a good voice, and I can make fun of others by making a sound.
