The UTAET is a voice trainer which is designed to build respiratory muscle strength and performance for individuals seeking a powerful voice. The idea was inspired by Karaoke. This new product was developed by a professional voice coach. The word "UTAET" is a combination of two words; sing and diet in Japanese. The hollow-cone form allows the sound current to pass though into an earpiece through a connected tube. It allows users to listen to their own voice and make incremental improvement over a period of time. In addition, users can enjoy voice training anywhere, anytime without worrying about disturbing others.
