VoxApp vs Resonali

IMPORTANT SAFETY NOTICE: VoxApp is intended SOLELY for educational and research purposes. Results should NOT be used for clinical diagnosis without a complete professional voice assessment by a qualified healthcare provider. This app is a supplementary tool for voice documentation and monitoring by trained professionals. VoxApp is the most comprehensive voice acoustic analysis app for vocal health professionals and researchers. Capture standardized recordings and obtain objective acoustic indices (AVQI, ABI, F0) for clinical documentation, research, and longitudinal voice monitoring. KEY FEATURES: • Standardized recording protocol (sustained vowel + connected speech) • Automatic AVQI (Acoustic Voice Quality Index) calculation • Automatic ABI (Acoustic Breathiness Index) calculation • Fundamental frequency (F0) analysis with visual contour • Report export in PNG and PDF formats • Complete evaluation history • Multilingual interface (Portuguese, English, Spanish, German, Italian) IDEAL FOR: • Speech-language pathology students and professionals • Otolaryngologists and voice clinics • Speech therapy researchers • Voice science laboratories • Voice professionals (singers, teachers, actors) working with their SLP SUBSCRIPTION PLANS: • Basic: Essential acoustic analysis features (3 free uses, then subscription required) • Professional: Advanced features + unlimited analyses + priority support + unlimited exports IMPORTANT TECHNICAL NOTES: • Requires internet connection for analysis (cloud-based Praat processing) • AVQI/ABI cutoff values were validated with laboratory-grade microphones, not phone microphones • Phone recordings use automatic gain control (AGC/AFC) and are more affected by background noise • Results must be interpreted with caution and in conjunction with complete clinical assessment • Best performance in quiet environment • Maintain consistent recording conditions for longitudinal monitoring PRIVACY & SECURITY: • Your data is encrypted and stored securely • GDPR compliant and health data regulations compliant • Voice recordings processed on secure servers • No data shared with third parties WHY VOXAPP? VoxApp brings professional-grade acoustic analysis tools directly to your smartphone, based on internationally validated protocols and acoustic indices used in clinical research worldwide. Designed for educational use and professional voice documentation.

Resonali is a clinician-facing acoustic voice analysis tool designed for speech-language pathologists. Built by an SLP for SLPs, Resonali helps clinicians complete structured voice measurement tasks, review acoustic and aerodynamic measures, compare results with reference data, and generate organized summaries for clinician review and documentation support. Whether voice evaluations are part of your daily caseload or something you complete only occasionally, Resonali is designed to make objective voice data clearer, faster, and easier to organize. VOICE MEASURES IN ONE PLACE Resonali supports selected acoustic and aerodynamic voice measures, including: • Maximum Phonation Time (MPT) • S/Z ratio • Mean, minimum, and maximum fundamental frequency • Pitch range • Glide-based highest and lowest F0 • Jitter • Shimmer • Harmonics-to-Noise Ratio (HNR) • Cepstral Peak Prominence (CPP) • Mean, minimum, and maximum intensity • Dynamic intensity range • Selected formant measures • Acoustic Voice Quality Index (AVQI) • Dysphonia Severity Index (DSI) • Laryngeal DDK task measures GUIDED VOICE WORKFLOW Record directly in the app or upload existing audio files. Resonali guides clinicians through structured voice tasks with clinician-facing prompts and task instructions. Supported tasks may include sustained phonation, pitch glides, connected speech, Rainbow Passage reading, intensity tasks, and laryngeal DDK tasks. REFERENCE-INFORMED RESULTS Resonali helps organize objective voice data into clinically useful summaries. Features include: • Reference-range comparison • Visual result indicators • Organized acoustic and aerodynamic results • Exportable PDF summaries • Text export for documentation support • Built-in Voice Measures Guide • Reference category options, including female, male, transgender, and nonbinary/no sex-based reference options • De-identified workflow designed to minimize entry of patient-identifying information BUILT FOR SLPs Resonali is intended for speech-language pathologists, graduate student clinicians under supervision, and other qualified professionals using the app within the scope of their training and role. Resonali supports clinical workflow, documentation, and review of objective voice measures. It does not replace clinical judgment, instrumental assessment, medical evaluation, referral, or follow-up. SUBSCRIPTION ACCESS Resonali requires an active subscription for access. Subscription options may include weekly, monthly, and annual plans. Pricing is shown before purchase and subscriptions are billed through your Apple ID. Subscriptions may be managed or canceled in your App Store account settings.
