Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Rights And Consent Before You Release A Song
Voice conversion and cloning require permission from the person whose voice or recording is used. Keep a record of that permission, and read each platform’s licence before monetising or distributing a track. The listed tools impose different boundaries: LyricToMelody AI includes commercial rights on paid plans; Kits AI may require approval for artist-model outputs; Voice-Swap ties commercial use to the applicable voice licence; Revocalize AI limits commercial licensing to paid plans; and ACE Studio has voice- and feature-specific exceptions.

Quick Recap
A Practical Selection Path
- Choose synthesis when you want to enter lyrics or MIDI and edit the generated performance: LyricToMelody AI, Synthesizer V Studio 2 Pro, ACE Studio or VOCALOID6.
- Choose conversion when you already have a sung performance and want another authorized voice: Kits AI, Audimee, Voice-Swap or Revocalize AI.
- Choose self-hosting when local control matters more than setup time: Applio or RVC WebUI.
- Before building a project, verify the vendor’s current language, genre, export and commercial-use details because the supplied product information does not establish support for every musical style or release scenario.
