This app is realtime voice changer that can work without headphones. When you speak, it will speak together with you making your voice to sound like alien robot. The aggressive feedback cancelation is the unique feature of Helium Speaker so you can put your phone inside your inner pocket and joke with people on Halloween or use it for cosplay. The app has 2 voce changing modes and sound a bit like 8-bit record. Helium Speaker also can function as Audio Unit effect inside AU hosts. It is high tech app made to be fun.
