What does my confidence score mean?
Your confidence score is not a grade on your voice. It measures how well HumMatch knows your voice: how much trustworthy pitch data we have collected across your hums. The better we know your voice, the better we can match you with songs.
Why it matters
Every song match and every singability percentage you see on HumMatch is calculated from your Vocal ID. A higher confidence score means a sharper Vocal ID, and a sharper Vocal ID means better matches: song rankings sorted for your actual voice, honest warnings before you pick a karaoke song that sits too high, and playlists you can genuinely sing. A low score means we are still guessing at the edges of your range, so some matches will be off.
It grows across sessions
One hum is a snapshot; several hums are a map. Humming is unlimited and free for everyone, so hum as often as you like: each clean session sharpens the measurement. HumMatch keeps the best of every session: if you reach a higher note on Tuesday than you did on Monday, that note is stored in your Vocal ID permanently. It takes about five clean sessions to push the score into the 90s, and each one makes your matches noticeably smarter.
What each hum is scored on
Two things: hum length and pitch steadiness. Cutting a note off early or humming very quietly leaves fewer samples to read. A wavering pitch, background noise, or the microphone sitting too far away makes the detected pitch drift. Both pull the reading down even if the note itself was right.
How to raise your score
- Hum, don’t sing. Close your lips and hum “mmm”, no words or lyrics. A clean hum reads far more accurately than singing.
- Come back for a few more sessions. Your score is built from your best takes across days, not just your last one.
- Find a quiet room and mute anything playing in the background.
- Hold your phone or microphone a few inches from your mouth.
- Hum each note for the full prompt with a clean, sustained tone.
