Pocket Singer is a multimedia application available on the iPhone that allows users to create their own original character (OC) and customize their voice. With the help of an AI voice engine, users can design various types of voices by adjusting the VoiceMix settings and selecting the vocal range for their OC.

In addition to creating and customizing the OC's voice, Pocket Singer also offers the option to create a 3D avatar by choosing from a range of makeup, hairstyles, costumes, and accessories. Alternatively, users can upload an image of their existing OC.

One of the standout features of Pocket Singer is its ability to produce music using the OC's voice. Users can import MIDI files and add lyrics to create their own songs. They can also import song projects shared by other Pocket Singer users. The application allows users to tune and generate the song, and export it as a video or audio file.

Pocket Singer supports multiple languages, including English, Japanese, and Chinese, making it accessible to a wide range of users.
