## What is VocalLens?

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.

### 1/5 — AIがわかりやすい！

*2026-09-03*

自分の声がどのタイプか出るので面白いなと思いました！

AIとのチャットは朗読向きって出たけど、実際の読むセリフとかあると練習しやすいな？と思いました！！

今後のAI機能に期待を込めて厳しめですが⭐️1です‼️

**Developer response:** コメントありがとうございます！声のタイプ診断を楽しんでいただけて嬉しいです😊
朗読の練習用に実際のセリフや文章があると練習しやすい、というご意見、とても参考になりました。
今後のアップデートで検討させていただきます！

もしよろしければ、内容にご満足いただけているようでしたら、
評価もご検討いただけると励みになります。
今後ともよろしくお願いいたします！

### 1/5 — クソ評価

*2026-08-13*

いい声でないのに弱点がないとかいい加減なアプリです。
ふざけてます？

### 5/5 — 面白い

*2026-07-14*

ケプストラムピーク顕著性という項目だけやたら高く出るんですが皆さんそうですか？

**Developer response:** ざわ2357さん、★5のご評価をありがとうございます！ケプストラムピーク顕著性（CPP）は声帯がどれだけ規則的に振動しているかを示す指標で、声帯がしっかり閉じている方ほど高く出やすい傾向があります。多くの方で比較的高めに出るのは自然な現象ですのでご安心ください。今後もアプリの精度向上に取り組んでまいりますので、どうぞよろしくお願いします！

### 2/5 — なんで

*2026-07-11*

特典として広告消えるって言ってたのに長い質問答えてからも広告流れ続けるのなんでですか

**Developer response:** (｀Д´)さん、ご不便をおかけし申し訳ございません。アンケート特典で非表示になるのは「録音完了直後に表示される広告」のみで、詳細スコアやAIコーチのアドバイスをご覧いただく際の広告視聴は特典の対象外とさせていただいております。紛らわしい説明で誤解を招いてしまい申し訳ございません。次回アップデートで表記をわかりやすく改善いたします。引き続きよろしくお願いいたします。

### 5/5 — 素晴らしい

*2026-06-03*

素晴らしい

**Developer response:** 令和の剣士 誠さん、★5のご評価と温かいお言葉をありがとうございます！「素晴らしい」というお言葉、開発の励みになります。引き続き声質分析の精度向上に取り組んでまいりますので、どうぞよろしくお願いします。
