Rate My Voice — Free Vocal Analysis

Speaking Voice vs. Singing Voice: Which Are You Rating?

“Rate my voice” can mean two different things depending on what you’re looking for.

If you’re thinking about your speaking voice — how you sound in presentations, videos, or conversations — the most meaningful dimensions are resonance placement, clarity, and the fundamental pitch you tend to speak at. Most adults speak at a pitch somewhere in the middle of their comfortable singing range, and a higher or lower speaking pitch correlates with how authoritative or approachable you sound to listeners.

If you’re thinking about your singing voice — your range, voice type, and how you compare to professional singers — that’s exactly what VocalCheck measures: the span from your lowest comfortable note to your highest, mapped to the seven classical voice types (Bass through Soprano).

VocalCheck focuses on the singing voice, but the data crosses over: knowing your singing range often explains why your speaking voice sits where it does.

What Does It Mean to Rate Your Voice?

When people search “rate my voice,” they’re usually looking for objective information about their voice — their range, their voice type, and how they compare to other singers. VocalCheck focuses on exactly that: measurable, neutral data about your voice.

Your voice is unique. Rather than applying a score like a competition judge, VocalCheck gives you:

• Your vocal range in musical notation (e.g., A2 to G4)
• Your voice type classification (Bass, Baritone, Tenor, Contralto, Mezzo-Soprano, or Soprano)
• Your range in octaves so you can track progress over time
• A comparison to famous singers so you know you’re in good company

What Makes a Voice “Good”?

The most celebrated voices in history come in all shapes and sizes. What makes them stand out is not their voice type, but how well they use what they have.

• Tone quality develops with vocal exercises and proper technique.
• Range can be expanded with consistent, guided practice.
• Control — the ability to hit notes accurately and hold them — improves with ear training.
• Expression — how emotion comes through in a performance — is a uniquely human skill no algorithm can rate.

VocalCheck gives you the first data point: your range. What you do with that information is up to you.

How to Use VocalCheck to Analyze Your Voice

1. Open the tool — no account needed.
2. Allow microphone access — only used for real-time pitch detection.
3. Sing your lowest comfortable note for a few seconds.
4. Sing your highest comfortable note for a few seconds.
5. View your results — range, voice type, and famous singer comparisons.

The entire process takes under 30 seconds.

Understanding Your Voice Type

Soprano (C4–C6)

The highest female voice type. Sopranos often lead operatic roles and pop ballads requiring powerful high notes. Famous sopranos: Celine Dion, Whitney Houston (in her prime), Mariah Carey.

Mezzo-Soprano (A3–A5)

The middle female voice. Warm, rich in the middle register. Famous mezzo-sopranos: Adele, Amy Winehouse, Beyoncé.

Contralto (E3–E5)

The lowest female voice. Rich, powerful lower tones. Famous contraltos: Cher, Toni Braxton.

Tenor (C3–C5)

The highest common male voice. Bright, forward tone. Famous tenors: Bruno Mars, Ed Sheeran, Freddie Mercury (partially).

Baritone (A2–A4)

The most common male voice type. Warm and versatile. Famous baritones: Elvis Presley, Frank Sinatra, John Legend.

Bass (E2–E4)

The lowest male voice. Deep, resonant tone. Famous basses: Johnny Cash, Barry White, Leonard Cohen.

How Does Real-Time Pitch Detection Work?

VocalCheck uses the Web Audio API to sample sound from your microphone at up to 44,100 samples per second. The Pitchy library then applies autocorrelation — a mathematical technique that identifies repeating patterns in the audio waveform — to extract the fundamental frequency of your voice. This frequency is mapped to the nearest musical note.

The process runs entirely in your browser with no server involvement. It typically achieves accuracy within a few cents (hundredths of a semitone).

Improving Your Voice After Rating It

Now that you have a baseline, here are the most effective ways to expand your range and improve your voice:

Warm up daily. Even 5 minutes of lip trills, humming, or gentle scales increases vocal flexibility over time.

Work at the edges. Your range extends at the top and bottom by carefully practicing notes just beyond your comfortable range. Approach them gently — never strain.

Practice breath support. Most singing problems (cracking, straining, going flat) are breath problems. Diaphragmatic breathing exercises are foundational.

Record and listen. Your voice sounds different to your ears through bone conduction versus recorded audio. Listening to recordings helps you identify specific areas to improve.

Retest regularly. Come back to VocalCheck every few weeks to measure progress. Even small improvements are motivating when you can see them on a piano keyboard.

Your Privacy: Your Voice Never Leaves Your Browser

Many voice rating apps send your audio to a server for analysis. VocalCheck works differently.

All pitch detection happens locally in your browser using the Web Audio API. Your microphone audio is never transmitted to any server, never stored, and never associated with your identity. The only thing VocalCheck does with your voice is calculate a pitch value — a number — in real time. When you close the tab, that data is gone.

Your results are stored entirely in the URL you can choose to share (or not). The shareable link encodes your lowest note, highest note, and voice type as URL parameters — no database, no account, no tracking tied to your voice recording.

This matters if you’re recording your voice in a private context — at home, in a practice room, or as part of vocal health monitoring. No audio files, no profiles, no data retention.
