Like most of our weird beauty posts this strange invention is from Japan. Can you guess what it is?

This strange mouthpiece comes with a tuning fork and is said to make your voice sound sweeter when used for five minutes everyday. ‘The Beauty Voice Trainer’ claims it works in three ways. Firstly, it positions the tongue to open the voice passage, allowing a much stronger sound. Secondly, it helps with abdominal breathing, and finally the tuning fork trains you to reach the correct note.

It all looks a bit crazy to me, but would you use a Beauty Voice Trainer?
