# Voice cloning best practices

> Get better cloned voices by improving sample quality, consistency, and volume before you generate a final dub.

# Voice cloning best practices

Better cloning starts with better source material. Small improvements in the source audio can make a noticeable difference in the final voice.

## Keep the samples clean

Aim for speech that is:

* clear
* dry
* low-noise
* free from heavy music or crowd sound

The quality of the capture matters more than the file format itself.

## Use consistent speech

The model responds better when the sample material sounds like one coherent speaking style.

Try to keep:

* a similar recording environment
* a similar speaking tone
* a similar energy level

If the source swings between whispering, shouting, noisy clips, and clean narration, the cloned result can become less stable.

## Match the performance you want

Cloned voices tend to inherit the style of the sample material.

* calm samples produce calmer output
* expressive samples produce more expressive output
* rushed delivery can create rushed output

If you want a clean, steady narrator feel, source clips with that same style usually work better.

## Use enough audio, but not too much

As a rule of thumb:

* use at least about 1 minute of useful speech when possible
* 1 to 2 minutes of clear material is usually a strong range
* more than about 5 minutes gives little practical gain in most cases

## Keep the volume balanced

Try to avoid samples that are:

* too quiet
* clipped or distorted
* heavily normalized to the point of sounding unnatural

A balanced recording level is better than an aggressively loud one.

## Prefer the right isolation mode

For most projects:

* start with `Studio`
* switch to `Realistic` only when the environment character is part of the experience
