Your signal, made useful

See more than volume.

VocalMax turns a short sample into a clear practice baseline, then shows which measurable skill deserves attention next.

Evidence without theatre

We only train what the microphone can measure.

Every course shows its sources, limits, target, and stop rules before you begin.

MEASUREMENT FIRST

Feedback, not diagnosis.

We use observable acoustic features such as voiced duration, pitch variation, intensity range, and timing. We do not infer health, personality, attractiveness, or social worth from your voice.

VISIBLE REASONING

Sources stay attached.

Read the rationale, evidence level, measurement boundary, and safety limits behind each drill.

PERSONAL BASELINES

Progress means your progress.

Compare repeated attempts with your own comfortable voice instead of chasing one universal sound.

Privacy by architecture

Your voice never needs to leave your phone.

Calibration audio, speech recognition, and acoustic analysis run on-device. Delete local calibration data whenever you want.

Questions, answered

No fine-print surprises.

What VocalMax measures, stores, and sells is deliberately clear.

Does VocalMax upload my recordings?+

No. Voice capture and analysis run on your device. A purchase transaction ID is sent to our Cloudflare service only when we verify Premium access.

Is this speech therapy or medical advice?+

No. VocalMax is an educational practice tool. It does not diagnose, prevent, or treat a voice, speech, breathing, or medical condition.

What makes the drills evidence-informed?+

Each course exposes its rationale, measurement boundary, source list, and stop rules. We separate measured feedback from claims the microphone cannot support.

Can I try it before subscribing?+

Yes. Your first calibration and the first drill in every course are available to try. Premium unlocks the complete curriculum and saved progress.

Your next voice is still yours
