How to Use the Vocal Range Test

Before You Start

Oniki Check is an online vocal range test that estimates the pitch of your voice from your browser microphone. You do not need to install an app or create an account.

Use a quiet room and keep the microphone around 20 to 30 cm from your mouth. Phones work, but room noise and speaker feedback can make pitch detection less stable.

Testing Flow

1. Press "Start recording" on the home page.
2. Begin with a low note that feels comfortable.
3. Move slowly upward through your range.
4. Stop before strain appears, then check your lowest note, highest note, and measured range.

Run the vocal range test more than once under similar conditions. The result will be more useful when you can see the normal variation.

How to Read the Result

Notes are shown as C4, A3, and similar pitch names. C4 is middle C on the piano, and A4 is the common tuning reference.

Your lowest and highest notes are the detected extremes during the test. They are not always the notes you can use comfortably in a song, so leave some margin when choosing keys.

If Detection Feels Unstable

• Check that microphone permission is allowed.
• Use headphones to reduce speaker feedback.
• Avoid breath noise, heavy vibrato, and shouting.
• Hold each note a little longer and repeat the test.
