DAF Professional

DAF Pro - Professional Speech Therapy App for Fluency & Clarity DAF Pro is the world's leading speech therapy app using delayed auditory feedback (DAF) technology, trusted by thousands across 100+ countries. This professional fluency therapy tool helps people with stuttering, stammering, Parkinson's disease, dysarthria, and speech disorders achieve clearer, more controlled speech through real-time auditory feedback. Designed by a certified Speech-Language Pathologist (MSc, PGDip, BAHons, HPC registered, RCSLT member), DAF Pro delivers ultra-low latency (20ms on Google Pixel devices) making it the most responsive speech therapy app available for Android. What is Delayed Auditory Feedback? Delayed auditory feedback (DAF) is a clinically recognized speech therapy technique that helps control speech rate and improve speech fluency. By hearing your voice with a slight delay, DAF encourages slower, clearer speech and reduces speech impediments. This evidence-based therapy method has been proven effective for stuttering therapy, stammering treatment, and Parkinson's speech rehabilitation. Who Benefits from DAF Pro? • Stuttering & Stammering: Reduces speech blocks, repetitions, and prolongations while promoting fluent speech • Parkinson's Disease: Controls speech rate, reduces dysarthria, improves speech clarity and intelligibility • Dysarthria & Motor Speech Disorders: Enhances articulation and speech precision • Speech Therapy Patients: Provides portable therapy for home practice and skill generalization • Speech-Language Pathologists: Professional-grade clinical tool for therapy sessions Key Features: ✓ Ultra-Low Latency: Industry-leading 20ms delay for natural, real-time feedback ✓ Background Mode: Continue speech therapy while using other apps or making calls ✓ Customizable Settings: Adjust delay time, pitch shift, microphone boost, and noise gate ✓ Recording & Playback: Track your progress and practice sessions ✓ Therapist-Designed: Developed by certified SLP using evidence-based techniques ✓ Privacy-Focused: GDPR compliant, no data collection, works offline Why DAF Pro Stands Out: Unlike consumer speech apps, DAF Pro is a professional-grade therapy tool designed for clinical effectiveness. Our advanced audio processing delivers the fastest response time, while background audio mode allows continuous therapy during daily activities - features unavailable in competing stuttering apps or speech therapy tools. Proven Results: Delayed auditory feedback has been shown in clinical research to help 1 in 3 people who stutter achieve significant fluency improvement. Many users with Parkinson's disease report better speech rate control and reduced dysarthria symptoms when using DAF therapy consistently.
