Utavie does not stop at a single score. It breaks a performance into pitch, stability, expression, technique, and rhythm. Pitch shows how closely you followed the guide melody, stability reflects long tones and wobble, expression captures dynamics and phrase movement, technique highlights singing elements such as vibrato, and rhythm focuses on timing. The goal is to find the weakest axis and turn the result into the next practice step.
A 30-second range test measures what you can sing. Spot songs pitched too high or too low before you start, and practice in the key that fits your voice best.
Utavie is not a music distribution service. It is a BYOM practice tool that loads audio files you legally obtained and are allowed to use. Lyrics can be supplied by loading a lyrics file or pasting text, but should be used only within the rights you have. Audio processing happens in the browser by default; when an advanced feature requires external API processing, it is handled according to the in-product notice and privacy policy.
After you find a weak scoring axis, use the singing guide to understand the cause and practice method. If pitch is weak, read about matching pitch. If your voice is unstable, check long-tone and range exercises. If you want more expression, read about vibrato and phrasing, then sing again in Utavie and compare the result.
Not sure where to start? These guides cover getting started, reading the pitch bar, choosing a key that fits your range, and fixing a low rhythm score.

Not for scoring. Utavie builds the guide melody from the vocals in the original song, so a track without vocals has nothing to compare your pitch against. You can still see lyrics and play the backing track.
You can load both. The guide melody comes from the original, and the karaoke track is used as the backing.
