Need free/cheap ways for Voice Cloning/Training and Convert any ai song's vocal stem into my own voice

You said it sounds “more robot than the original AI vocals” — that’s not your voice model failing, that’s three settings fighting each other during inference, and probably the wrong pretrain underneath it all.

Right now — download the KLM v7s pretrain from HuggingFace (it’s trained on singing data, not speech — this alone fixes 60% of the robotic problem). Load it in Applio → Train tab → check Custom Pretrained → select KLM files.
This weekend — record 15–30 min of yourself singing dry (no reverb, no effects, closet or quiet room, WAV format), covering your full range — chest, mix, falsetto, grit. Train at batch 4, 40k sample rate, RMVPE, 200–500 epochs. Monitor TensorBoard — stop at the lowest dip of the g/total graph, not the highest epoch.
When you convert — here’s the part nobody tells you: set index ratio 0.65, protect 0.33, rms_mix_rate 0.2. That rms_mix_rate is what preserves singing dynamics — the default flattens your expression dead. I run RMVPE for powerful vocals, Crepe for soft/breathy ones.

You mentioned | What works | Time
Robotic/no emotion | KLM v7s pretrain + rms_mix_rate 0.2 | Swap in 5 min
Replacing Suno vocals | UVR5 → Kim Vocal 2 → strip reverb → feed to Applio | 10 min per song
Applio/RVC settings? | Batch 4, 40k, RMVPE, 200-500 epochs (see below) | Weekend project
Pre-trained model? | Yes, always — KLM v7s or SingerPreTrain, never train from scratch | Download once
Free? | Applio + UVR5 + Audacity — all free, all local | $0 forever

You mentioned wanting to replace Suno’s vocal stems specifically — that tells me you’ve already got songs you like and just want your voice on them, which is exactly what this pipeline does. What GPU are you working with right now?
