Open tool →Voice Type Test
Sing or type your notesTakes your lowest, highest and easiest note and compares them with a chart of common voice types, with a soprano-or-alto and tenor-or-bass answer. Handy for choir singers picking a section.
Open tool →High Note Test
MicrophoneA climbing game with rising target notes. It reports the highest note you could hold, as a note name and in Hz.
Open tool →Pitch and notes
See what you sing, note by note.
Pitch Accuracy Test
Microphone (hearing test needs none)Plays a note for you to sing back and shows how many cents sharp or flat you were, with a score out of 100. It also has a higher-or-lower hearing test.
Open tool →Singing Grader
MicrophoneGrades a short take from 1 to 10 from pitch centring, steadiness, clear-pitch time and range used. It does not judge rhythm, tone or musicality.
Open tool →Singing Note Detector
MicrophoneShows the note you are singing right now with its Hz and how sharp or flat it is, then lists the notes you held.
Open tool →Note Finder
Microphone or audio fileReads notes from your microphone or an audio file and shows them on a staff and a piano keyboard, with transposing-instrument settings.
Open tool →Voice analysis
Look at the sound of your voice rather than a note target.
Voice Frequency Test
MicrophoneMeasures the fundamental frequency of your speaking or singing voice in Hz and gives the average and nearest note.
Open tool →Voice Quality Test
MicrophoneTakes one held vowel and reports four descriptive readouts: pitch evenness, loudness evenness, clarity and brightness. No score, and not a medical test.
Open tool →Scales and song keys
Choose what to sing.
Vocal Scale Finder
Sing, hum or tap notesListens to the notes you sing and ranks the five best-fitting of 72 scales, so you can see what scale or key a tune sits in.
Open tool →Vocal Pitch Changer
Microphone or audio fileShifts a recording, or a take you make in the page, up or down without changing its speed. Useful for moving a song into a key that fits your range.
Open tool →How to read the results
These tools estimate pitch from what your microphone hears. Room noise, microphone quality and the audio processing your browser applies all change the numbers, and one reading is a snapshot of one moment. Voice-type and range labels are conventions, not fixed rules.
Read what can affect your results before drawing conclusions, and see the testing methodology for what each tool measures and what has and has not been tested. Never force painful notes to raise a result.
