# Let AI Detect Lyrics

> Use AI to automatically transcribe and sync lyrics from your audio

Don't have the lyrics? Let AI listen to your song and transcribe them automatically.

## When to Use Auto-Transcription

This option works well when:

* You don't have access to the song's lyrics
* The song has clear, understandable vocals
* You want a quick solution without manual input

## How to Use Auto-Transcription

1. On the Create Karaoke page, select **Detect from audio**
2. Select the language of the song
3. Click **Create Karaoke**

The AI will:

1. Listen to the audio
2. Identify and transcribe the lyrics
3. Sync each word to the music

## Results and Accuracy

Auto-transcription works best with:

* Songs with clear vocals
* Standard pronunciation
* Minimal background noise

You may need to review and correct:

* Misheard words
* Song-specific terms or names
* Stylized pronunciations

## After Transcription

Once your karaoke is created:

1. Open your project
2. Check the lyrics for accuracy
3. Use [Edit Lyrics](/en/web/edit-lyrics) to fix any errors
4. Use [Manual Sync](/en/web/manual-sync) to adjust timing if needed

## Transcription Credits

Auto-transcription uses credits based on the song duration and the AI model selected. You can see the credit cost before creating your karaoke.

## Advanced Settings

Under **Advanced Settings**, you can choose different AI models:

* **AudioShake** — Best accuracy for most songs
* **MusicAI** — Premium detection with syllable-level timing
* **Whisper** — Budget-friendly option

Each model has different credit costs and accuracy levels.
