How to Use the Vocal Range Test in 3 Steps

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. The guided test takes about one minute. Do not test when your voice is painful or hoarse.

Press “Start test (allow microphone)” on the home page. Oniki Check guides you through your lowest chest note, highest chest note, and optional falsetto note. Audio stays in your browser and is not uploaded as a recording.

Step 1: Lowest Chest-Voice Note

Start with an easy “ah” near your speaking voice and move gradually lower. Use a note you can sustain without pushing your larynx down or turning it into a growl.

Hold near the same pitch for about 1.2 seconds. When the progress reaches 100%, the step records that note. A lower stable note will update the result.

Step 2: Highest Chest-Voice Note

Return to an easy middle note before moving higher. Stop before shouting and keep only notes you could repeat inside a song.

Once a stable high note is recorded, choose whether to add falsetto or view the result.

Step 3: Highest Falsetto Note (Optional)

Use a light falsetto or head voice and hold the highest painless note. It is shown separately from your chest range, so it will not be mistaken for a repeatable chest-voice high note.

How to Read the Result

The result shows both scientific pitch notation such as C3–G4 and Japanese karaoke notation such as mid1C–mid2G. See the Japanese karaoke pitch notation chart if those labels are new to you.

“Repeatable chest range” uses the notes held for at least 1.2 seconds in the guided steps. “Detected extreme” can include brief sounds or noise, so use the repeatable range first for songs.

Use the result’s karaoke action to read the karaoke key guide, which considers both the low and high ends of the song.

When to Repeat the Test

Repeat the test two or three times under similar conditions. If results jump wildly, repeatedly show C7, or microphone permission fails, see Testing Tips for noise, browser, and permission troubleshooting.
