VocalLens - Voice Coach

About this app

Sound like the voice you hear in your head. VocalLens analyzes the quality of your voice — not just pitch — and shows you exactly what to work on. Record for 10 seconds and get a science-based score across four dimensions: Richness, Power, Presence, and Brightness. ■ Built for · Singers who want a richer, more resonant voice · Podcasters who want to sound clear and authoritative · Content creators leveling up their on-camera presence · Public speakers and presenters building vocal confidence · Voice actors refining tone and breath control · Anyone who wants to love the sound of their own voice ■ Key Features [Mic] 10-Second Voice Analysis Speak into the mic for 10 seconds — no complicated setup, no musical training required. Your results appear instantly. [Chart] 4-Axis Voice Quality Score · Richness: how much air escapes versus clean tone · Power: harmonic richness and vocal clarity · Presence: energy in the 2–4 kHz "cut-through" range · Brightness: the height of your spectral center of gravity All visualized on a radar chart so you see your voice's full shape at a glance. [Tip] Personalized Practice Exercises Every session delivers specific exercises matched to your score — nasal consonant drills, yawn-breath openers, forward resonance vowels, and 10+ more per dimension. Exercises rotate randomly so practice stays fresh. [Graph] Track Your Vocal Progress Compare recordings day by day and week by week. The more you practice, the clearer your strengths and growth areas become. [Guide] Voice Type Diagnosis Your scores map to one of 16 voice types — like "Bedrock," "Crystal," or "Pearl." Each type comes with strengths, common challenges, and what it's best suited for. [AI] AI Voice Coach (via Rewarded Ad) Ask the AI about your voice using your actual score data. Get tailored advice on issues like "my high notes crack" or "my voice doesn't carry in meetings." ■ Privacy First Voice recordings are processed entirely on your device. When using AI coaching, only your score numbers and your text question are sent — your audio is never transmitted anywhere. ■ Important Notice · This app is not a medical device and does not provide medical diagnosis or treatment. · Stop use immediately if you experience pain or discomfort in your voice or throat. · AI responses are for reference only and may contain errors. · Individual results may vary.
