Start karaoke scoring in your browser, without an install
Utavie turns an audio file you provide into a practice session in the browser. Check the device, microphone, privacy boundary, and first-run preparation before you begin.
- No app installation
- Audio prepared on your device
- Five scoring dimensions
Bring an audio file, a microphone, and a current browser
Use an audio file you have the right to use and a device that can grant microphone access. Lyrics can be added later, so the audio file is enough to begin preparation.
A current desktop browser is the most predictable environment. Mobile availability and preparation time vary with device memory and processing power.
- Allow microphone access
- Keep the tab open during preparation
- Follow the conversion guidance for unsupported formats
Preparation stays in the browser
Vocal separation, pitch analysis, and score calculation run on the client. Your audio is not sent to a separation server to create the karaoke material.
The first run may download AI models and analyse the file, so it is different from instant streaming. Prepared material may be reusable from the local library on the same device.
Use five dimensions to choose the next practice target
The result separates pitch, stability, expression, technique, and rhythm. Look at the lowest dimension and the singing graph instead of treating the total as the only answer.
- Pitch: agreement with the guide melody
- Stability: consistency on sustained notes
- Expression, technique, and rhythm: dynamics, detected techniques, and onset tendency
Before you start
- Keep a usable audio file on the device
- Confirm microphone permission
- Leave the page open during first preparation
- Try a shorter file first to check device compatibility
Browser scoring FAQ
- Is my audio stored on a server?
- Karaoke preparation is designed to run on your device. The audio itself is not uploaded for scoring unless you separately choose a feature that sends data.
- Can I use only a phone?
- It depends on the device and browser. Test with a shorter file first; if preparation is too heavy, try a current desktop browser.
- Can I score without lyrics?
- You can begin with pitch-focused feedback. Rhythm information that depends on lyric timing varies with the available lyric data.
