How it works
The definitive guide to changing lyrics with AI vocals.
Have you ever heard a song and wished you could swap out a few lines to make it your own — perhaps for a special gift, a personal project, or just for fun? The challenge has always been integrating those new lyrics seamlessly while keeping the distinctive voice of the original artist. Re-recording the entire track loses the essence of the original song.
But there is a way — through a combination of vocal recording, AI voice training, and careful mixing & mastering. Let us break it down in 5 simple steps.
Step 1
Separating the music and vocals
Before anything else, the original song needs to be split into its individual stems — vocals isolated from the instrumental. This is done using AI-powered stem separation tools. Our favourites are lalal.ai and vocalremover.org, which produce clean, high-quality separations with minimal bleed between tracks.
Step 2
Training the AI on the artist's voice
The isolated vocals from the original song become the training data for the AI voice model. It is most important that you use vocal samples taken directly from the song you want to change. This ensures that the AI learns the exact texture, tone, and character of the artist's voice in that particular context — ensuring the output matches seamlessly rather than sounding like a generic impression.
Step 3
Capturing the new performance
This is the most important step in making sure your lyric change sounds natural and "as if it was the original song." A skilled vocalist (or you) carefully performs the new lyrics so that the new words have the correct timing, rhythm, melody, and harmony to match the specific section of the song where they will be placed.
Step 4
AI voice conversion
The recorded vocals are run through AI voice conversion tools like RVC (Retrieval-based Voice Conversion) or online platforms such as kits.ai and similar tools — which transform the new performance into the voice of the original artist using the model trained in Step 2.
Step 5
Mixing & mastering
The AI-converted vocals are carefully inserted back into the original track. Volume, EQ, and effects are balanced so the new lyrics blend seamlessly — as if they were always part of the original recording.
The result: your words, their voice — virtually indistinguishable from the original. It will shock many people. And if you want someone to go through all this trouble for you, we are happy to do it at nicevois.com, just place your order and receive your perfect lyric change in 24-48 hours ☺️
