- Choose a short lyric phrase or record a vocal idea you have permission to use. Decide whether you want a performed take transformed or a new sung part made from notes and lyrics.
- For a performed take, try a conversion tool and compare distinct voice colors while keeping the same phrase and performance. For a written part, enter notes and lyrics in a singing synthesizer, or use LyricToMelody AI to explore a topline from lyrics or MIDI.
- Save versions with clear labels for the source phrase, model or voice, and settings you changed. This makes it easier to compare what changed when you bring the audio into your production workflow.
- Before sharing or releasing a result, confirm the platform’s current terms, the model’s permissions, and consent for any person whose voice or recording is involved.
