Training strength
How many epochs should you use for RVC?
An epoch is one complete pass through the prepared dataset. More passes increase training time, but they do not guarantee a better voice. The right number depends on the recording length, quality, variation, and how quickly you need a usable result.
NiceVois's starting recommendations
| Usable audio duration | Starting recommendation | What to expect |
|---|---|---|
| Under 1 minute | 25 epochs | A fast experiment; the source may be too short for a reliable model. |
| 1 to under 5 minutes | 100 epochs | The standard public-beta starting point. |
| 5 to under 10 minutes | 150 epochs | Available in larger personal workflows, outside the current beta limit. |
| 10 minutes or more | 200 epochs | A stronger baseline for larger datasets, outside the current beta limit. |
The public beta currently limits a run to five minutes and 100 epochs. The uploader enforces the limit shown for your workspace.
Undertraining versus overtraining
With too few epochs, the model may not capture a stable voice identity. With excessive training, it can overfit the particular recording and reproduce its quirks instead of generalizing cleanly. Source quality remains more important than chasing a large number.
Use checkpoints when time matters
The training workspace can publish an inference-ready checkpoint when one becomes available. That gives you a model to test before the final epoch target finishes. A checkpoint is useful for urgent work and for deciding whether the source audio is promising.
A practical decision rule
- Start with the duration-based recommendation.
- Test the resulting model on speech or singing that was not in the dataset.
- If identity is weak but the source is clean, consider a longer run.
- If artifacts mirror the dataset, improve the audio before adding more epochs.
Simple answer: for the current public beta, use the recommended 100 epochs for one to five minutes of clean audio. Use 25 only when you need a quick short-audio experiment.
Add your audio and the epoch dial will show the recommendation for its duration.
