THE LETROU GUIDE

How does song transcription work?

When you cannot find a song’s lyrics online, LETROU helps you create an initial draft from audio. You can review, correct and save the lyrics for singing, studying or rehearsing.

Why can automatic transcription make mistakes?

Speech recognition interprets sound, but singing is not the same as speaking. Instruments, reverberation, accents, choirs, prolonged pronunciation and low-quality recordings can confuse words. An automatic transcript is a starting point, not a certified version.

1

Upload audio or paste a link

Choose an audio file or paste a YouTube song URL. Only process material you have permission to use.

2

Check the generated text

Compare the transcript with the audio. Pay special attention to names, choruses, repetitions and the ends of lines.

3

Edit and organize

Use the editor to correct words, separate verses and save your personal version. Open Stage Mode or organize a set list for rehearsal.

Fictional correction example

Before: “The sun is shinning and the day will beggin”

After: “The sun is shining, and the day will begin.”

How do suggestions improve the public catalog?

Personal edits can remain saved only on your device. If you submit a suggestion to LETROU, our team can compare it with the published lyrics and approve or reject the correction. Suggestions never replace public lyrics automatically.

What can you do with reviewed lyrics?

  • Study the words and organize verses and choruses.
  • Increase the text size and use Stage Mode.
  • Prepare a set list for performances or rehearsals.
  • Share a repertoire and submit suggestions when allowed.

Frequently asked questions

Does LETROU guarantee every word is correct?

No. Accuracy depends on audio quality and the singer’s delivery. Human review is therefore important.

Can I change the original song lyrics?

You can create a personal edited version. A proposed change to the public page is reviewed before it can be published.

Can I use any song?

Respect copyright and submit only material you are authorized to use. You can contact us about content concerns.
