Use of the Site

Oniki Check is a free tool and guide for vocal range testing. You may use it for personal practice, karaoke key choice, and vocal training notes.

Results

Results can change with microphone, room, health, and technique. Do not treat the result as an absolute voice type classification or medical decision.

Lowest note, highest note, and comfortable range are estimates detected during the session. For song choice and practice notes, prioritize the range you can repeat without strain.

Prohibited Use

Do not disrupt the site, attempt unauthorized access, send excessive automated requests, or use the site in a way that violates others' rights.

Disclaimer

Oniki Check does not guarantee perfect accuracy or specific singing outcomes. Stop testing if you feel pain or discomfort.
