Available Tools
Vocal Formant Frequency Analyzer
Estimate vocal formant frequencies (F1, F2, F3) live from your mic with LPC, plotted on a vowel-space chart with a nearest-vowel guess. Approximate & speaker-dependent; for sustained vowels. Nothing recorded.
Launch tool →Vocal Frequency Range Tool
Sing your lowest and highest notes to map your range in musical notes, Hz, and octaves, with an approximate voice-type estimate (bass to soprano) and famous-singer examples. Live mic, nothing recorded; a rough snapshot.
Launch tool →Singing Range Detector
Guided range test: map your full range, estimate your tessitura (most-used region), suggest a choir part (SATB), and show the typical passaggio zone for your voice type. Passaggio is a reference, not measured. Live mic, nothing recorded.
Launch tool →Speech Clarity Tester
Read aloud and see your speech’s spectral balance across five bands plus a consonant-presence (2.5–6 kHz) score, with tips for muffled or harsh delivery. A spectral-balance proxy, not a true intelligibility score. Live mic, nothing recorded.
Launch tool →Vocal Pitch Checker
Check your singing pitch accuracy in real time against any target note. Cent deviation display showing sharp or flat, visual pitch tracking graph, overall accuracy percentage score, and note-by-note breakdown — for singers, choir practice, and audition preparation.
Launch tool →Voice Type Classifier
Estimate your voice type (bass, baritone, tenor, countertenor, contralto, mezzo-soprano, soprano) from your range and tessitura, with a confidence rating and a comparison chart. Range-based estimate (timbre not measured). Live mic, nothing recorded.
Launch tool →Accent Frequency Profiler
Speak naturally and see where your vowels land in F1/F2 formant space, built into a density footprint over reference vowels. A vowel-space footprint, NOT an accent identifier or scorer. Live mic, nothing recorded.
Launch tool →Overtone Singing Analyzer
Visualize and analyze harmonic overtone singing and throat singing (Tuvan, Mongolian) techniques. Real-time harmonic spectrum highlighting individual overtones above the fundamental, overtone isolation display, and technique improvement guidance.
Launch tool →Baby Cry Frequency Analyzer
Record and analyze your baby’s cry frequency patterns. Fundamental frequency and formant analysis, reference chart of typical cry characteristics for hunger, pain, tiredness, and discomfort, with research-backed context and medical disclaimer.
Launch tool →Voice Vibrato Analyzer
Hold a sustained note and measure your vibrato rate (Hz), depth (cents), and regularity in real time, with a pitch-fluctuation graph and an honest verdict (straight tone, even vibrato, wobble, tremolo). Live mic, nothing recorded.
Launch tool →Speech Frequency Spectrogram
Visualize your speech as a real-time scrolling spectrogram — frequency content over time with colour-coded intensity, a logarithmic frequency axis, an adjustable max frequency, and freeze. See vowels, formants and consonant bursts. Live mic, nothing recorded.
Launch tool →Vocal Resonance Analyzer
Sing a sustained vowel and see your voice’s spectral balance across five bands, its brightness (spectral centroid), and the strength of the “ring” (singer’s formant) that drives projection. An honest acoustic mirror, not anatomical placement. Live mic, nothing recorded.
Launch tool →Voice Gender Analyzer
Supportive feedback for voice training: tracks your average pitch (F0) and resonance (formants) and places your voice on a perceptual masculine↔feminine spectrum. Measures acoustics only — never determines gender or sex. Inclusive, for gender-affirming voice work. Nothing recorded.
Launch tool →Vocal Fatigue Detector
On a sustained vowel, tracks voice-steadiness proxies — pitch steadiness, jitter-like period perturbation, and shimmer-like loudness perturbation — into a 0–100 score. Capture a baseline and watch for drops over a session. Non-clinical, not a diagnosis. Nothing recorded.
Launch tool →Vocal Warmup Frequency Guide
Guided warmups — scales, arpeggios, a sustained vowel, and a siren glide — with a play-along reference tone (adjustable key & tempo) and live mic pitch feedback (in tune / sharp / flat). Plays sound; use headphones for accurate feedback. Nothing recorded.
