VOX Factory

VOX Factory is an audio editing tool that turns MIDI, lyrics or your own voice into finished AI vocals. VOX Factory is a browser and desktop vocal synthesizer that turns MIDI melodies and lyrics, or your own sung takes, into studio-quality AI vocals in English, Korean and Japanese.

VOX Factory is a vocal production suite built around an AI singing synthesizer. The workflow is closer to a vocal editor than to a prompt box: you supply a melody as MIDI, add lyrics, and the engine renders a sung performance. Alternatively, you can sing a part yourself and convert it, or pull melody and lyrics out of an existing recording with Voice to MIDI and rebuild the vocal with a different character. The suite is aimed at songwriters, producers and composers who need finished lead vocals, cover versions, guide vocals or choir parts without booking a session singer. The voice library is organized around named characters rather than generic presets, each tagged with genre strengths and a language. English, Korean and Japanese are supported natively, and a single phrase can mix all three. Voices are recorded from real singers and licensed through AudAi, which matters if you plan to release commercially. The site states that copyright in the finished song belongs to the user, that streaming distribution is allowed, and that the vocals themselves cannot be resold or used to train other AI models. Editing is deliberately compact. Four controls (intensity, vibrato, pre-bend and post-bend) cover most stylistic shaping, and a pitch curve editor handles fine detail such as legato phrasing or expressive vibrato. Partial Rendering re-synthesizes only the notes you changed, which keeps the edit loop fast. A Voice Changer keeps your own phrasing while swapping in a different character, which is useful for demos where the melody is already right. It sits between a DAW plugin and a standalone tool. The web app and desktop builds for macOS and Windows share the same experience and store projects in the cloud, while the VOX Link plugin syncs playback, tempo and time signature with a DAW. Compared with a full singing-synth editor it is lighter and faster to learn; compared with prompt-only song generators it gives far more control over the actual performance, at the cost of requiring a melody to start from.
