Change My Voice is a free Android application developed by RadonSoft that allows you to modify your voice in real-time after recording. With this voice processor, you can make your voice sound like a robot, an alien, a baby, and many more. You can also place yourself in different environments such as a pipe, a bathroom, a hall, or a station. Additionally, you can speed up, slow down, or alter the pitch of your voice.

The app offers a virtual unlimited combination of effects and rooms that give you full control over the sound of your voice message. It also features 3D processing that adds space when listened to in stereo, like with a headset. This version of the app allows real-time playback and set-up of all parameters. However, for saving, ring, notification, and alarm-tone functionality, you will need to purchase the pro version of VoiceProcessor.

Overall, Change My Voice is a fun and easy-to-use app that provides a unique and enjoyable experience for users who want to change their voice and add some fun to their recordings.
