About Oniki Check

Oniki Check is an online vocal range test for measuring your lowest note, highest note, and comfortable singing range from a browser microphone.

It is built for beginners, karaoke singers, and vocal students who need a quick way to understand their current range.

You can start the vocal range test on the home page. For result interpretation, read How to Use the Vocal Range Test and Vocal Range, Tessitura, and Voice Type.

What We Care About

  • Do not upload recordings.
  • Do not encourage unsafe testing.
  • Do not decide voice type from a single high note.
  • Explain results as a usable range singers can apply to songs and practice.

Disclaimer

Oniki Check is not a medical diagnosis or a replacement for professional evaluation. If pain or hoarseness continues, stop testing and talk with a qualified professional.
