Voice Changer by Sound Effects

Nova Play Mobile's Voice Changer by Sound Effects is a fuller-featured take on the voice-effect genre. Beyond turning your speech into a robot or a chipmunk, it adds text to speech, reverse playback, a sound effects library and video voice editing, making it as useful for short videos as for pranks.

The core is a large set of voice effects, with the developer citing more than 30: switch between male and female voices, or go for cartoon, robot, alien, giant, baby and chipmunk sounds. You can record new audio or import existing files, then fine-tune speed, volume and pitch, apply high-pass and low-pass filters or distortion, and trim clips. An AI text-to-speech mode generates speech from typed text, with control over language, voice style, pitch and speed. Reverse Voice plays a recording backwards. The sound effects library adds background sounds like rain, a barking dog, clapping and a camera shutter, and a video mode applies voice changes to your clips.
