# Clone Any Voice with AI in Seconds

> Replicate any voice from a short audio sample using Artnex VoiceZen, then generate new speech in that cloned voice from any text you provide.

Voice Cloning lets you capture the characteristics of a real voice from an uploaded audio sample and use it to speak any text you write. The cloned voice preserves the tone, cadence, and timbre of the original, producing output that sounds like the source speaker.

## Navigate to Voice Cloning

Go to **Tools > Audio > VoiceZen > Voice Cloning**.

## Clone a voice

<Steps>
  <Step title="Upload a voice sample">
    Click **Upload Audio** and select your reference audio file. Accepted formats are **MP3 and WAV only** — other formats are not supported.

    <Warning>Only MP3 and WAV files are accepted. Uploading a different format will produce an error and the file will not be processed.</Warning>

    For the best results, your sample should:

    * Be at least a few seconds of clear, uninterrupted speech
    * Contain a single speaker with no background music or noise
    * Be recorded at a consistent volume without clipping or distortion
    * Use a clean WAV or high-quality MP3 (128 kbps or higher)
  </Step>

  <Step title="Enter the text to speak">
    Type the text you want the cloned voice to say into the text field.
  </Step>

  <Step title="Select a language">
    Choose the output language from the language dropdown. Supported languages include Arabic, Chinese, Danish, Dutch, English, Finnish, French, German, Greek, Hebrew, Hindi, Italian, Japanese, Korean, Portuguese, Russian, Spanish, and Turkish.
  </Step>

  <Step title="Adjust advanced settings (optional)">
    Click **Settings** to fine-tune the generation:

    * **Exaggeration** (0.25–2.0) — Controls how expressive and dramatic the speech delivery is. Lower values are neutral; higher values amplify emotion.
    * **Temperature** (0.05–5.0) — Controls randomness. Lower values produce more predictable, consistent output. Higher values introduce more variation.
    * **CFG Weight** (2–10) — How closely the output follows the voice characteristics. A value of 0.5 gives balanced results.
    * **Seed** — Enter a specific seed to reproduce an exact output. Set to 0 for a random result each time.
  </Step>

  <Step title="Generate">
    Click **Create**. The tool uploads your audio sample, processes the voice, and generates the cloned speech. This may take longer than standard TTS — allow up to 30 seconds.
  </Step>

  <Step title="Download">
    Click the download button on the audio player to save your result as a WAV file.
  </Step>
</Steps>

## Credit cost

Voice Cloning costs **500 credits** per generation.

## Tips for clean audio samples

<Tip>A short, clean sample consistently outperforms a long, noisy one. Prioritize audio quality over duration.</Tip>

* Record in a quiet room with soft furnishings to reduce echo
* Use a dedicated microphone rather than a phone or laptop mic when possible
* Avoid samples with background music, reverb, or crowd noise
* Keep the speaker's mouth close to the microphone and at a steady distance
* Remove long silences or multiple speakers before uploading
