# VOXA — Voice Biomarker Analysis (mobilehealthcheck.online) > VOXA is a private, browser-based voice biomarker analysis tool for personal wellness and self-awareness. A user records 30–60 seconds of natural speech; VOXA measures 12 acoustic voice biomarkers and shows reproducible wellness indicators. Recordings stay in the user's browser; only extracted numeric measurements are sent, encrypted, to VOXA's analysis engine, which returns the results and does not store them. VOXA is not a medical device and does not diagnose. Free for 30 days, then $99 per month; cancel anytime. Key facts: - Product: VOXA, a web application that runs in any modern browser with a microphone; no install. - Input: 30–60 seconds of natural speech (live or uploaded); optional short face video for facial micro-expression analysis. - Method: Fast Fourier Transform analysis of 12 acoustic biomarkers — pitch centre, pitch variability, speaking tempo, volume variability, articulation precision, breath pattern, resonance, harmonic richness, pause frequency, spectral centroid, spectral spread and energy entropy (including jitter and shimmer). - Engine: deterministic (DHVS) — the same recording always yields the same result, enabling trend tracking. - Outputs: exploratory biochemical-tendency estimates (neurotransmitters, hormones, minerals, vitamins, toxin load) on a −100% to +100% balance scale — not laboratory measurements; research-linked voice-pattern indicators ranked into three evidence tiers with confidence below 100%; an optional personalised three-minute balancing soundscape (Solfeggio tones, golden-ratio harmonics, binaural beat, chakra tones) for relaxation. - Privacy: raw voice and video recordings never leave the user's device; numeric measurements (and any name/birth details the user enters) are sent over HTTPS to VOXA's analysis engine to compute results and are not stored there; results stay in the browser. Registration data (name, country, phone, e-mail) is used only to administer the subscription. Payments are processed by Stripe. No advertising; the public website uses Google Analytics only after the visitor accepts analytics cookies (never inside the VOXA application). - Pricing: 30-day free trial, then $99 per month. Cancel anytime; cancel during the trial and pay nothing. Payments are non-refundable except where the law requires otherwise. - Regulatory status: wellness and educational tool, not a medical device; outputs are indicators, not diagnoses or laboratory measurements. - Developer: Nonlinear Platform Development, Montréal, Québec, Canada.
