VoiceLab: Voice Analysis Coach

Practise a comfortable, deeper speaking voice with VoiceLab. Explore resonance and calm speaking without forcing low notes.

Work on intonation for presentations, podcasts and conversations. Live feedback marks detected falling sentence endings green and rising endings red, helping you practise unwanted uptalk consciously.

Use a voice pitch analyzer in hertz: the 10-second voice test shows live Hz, median pitch and your typical range. Choose comparison ranges yourself, with no automatic gender assignment.

• 5 free exercises: breathing, humming, exploring a lower range, sentences and reading
• Variants with flexible repetitions and a guided daily routine
• Personal target range and live pitch graph
• Local history with notes, training days, streaks and badges
• Optional daily reminder
• 10 languages, light/dark mode, phones and tablets

Your microphone audio stays on your device and is never saved as an audio file or uploaded. Saved pitch metrics and training data remain local. No account needed. Ads, optional Android speech models and Google Play reviews may use the internet. Word marking requires Android 13+ and an available on-device language model.

Your first valid analysis is ad-free. Afterwards, video ads may appear before new analysis results and after every third completed exercise. No permanent banner. Ad data is processed separately from your local audio. See the privacy policy and app settings for details and consent options.

VoiceLab is a learning and practice app, not a medical device. No diagnosis or guarantee of permanent voice changes. Pause if you feel strain, pain or hoarseness.
