About DictaLearn
Making effective English pronunciation practice accessible to everyone through AI-powered feedback and personalized learning.
The Story Behind DictaLearn
DictaLearn was created by an independent developer and language learner who experienced firsthand the frustration of unclear pronunciation feedback. Traditional pronunciation tools either provided no actionable feedback or required expensive tutoring sessions with limited availability.
Rather than relying on personal credentials, this platform is built on established speech recognition technology and adaptive learning principles informed by peer-reviewed research. The goal was simple: make effective pronunciation practice accessible to everyone, anywhere, at any time.
DictaLearn combines industry-standard AI speech recognition with adaptive learning algorithms to deliver instant, actionable feedback, solving the exact problem that inspired its creation.
The Journey
From Frustration to Solution
- →The Problem: Existing pronunciation tools lacked instant, detailed feedback. Self-study meant practicing without knowing if improvements were real or imagined.
- →Early Experiments: Started with basic browser-based speech recognition to test if automated feedback could actually help. Early prototypes validated that instant scoring drove faster improvement.
- →MVP Development: Built the core platform with three practice modes (Read Aloud, Repeat Audio, Type Audio) and a 6-tier adaptive system that adjusts difficulty based on performance patterns.
- →Beta Testing: Early users validated the approach, instant feedback combined with adaptive difficulty created measurable improvement in pronunciation accuracy and confidence.
Methodology
Speech Recognition Technology
DictaLearn uses two speech recognition approaches based on user tier:
- •Free Tier: Browser-based speech recognition for client-side processing with zero server costs and complete privacy
- •Pro Tier: Cloud-based AI for advanced server-side analysis with superior accuracy and detailed phonetic scoring
Adaptive Learning System
The platform uses a 6-tier progression system with internal difficulty levels:
- •Promotion Logic: Consistent 100% accuracy scores trigger advancement to harder content within the same group or to the next learning group
- •Reinforcement: Performance below thresholds provides additional practice at the current level to build mastery
- •Difficulty Adjustment: System tracks accuracy patterns across multiple exercises to determine optimal challenge level
Scoring & Validation
Each exercise receives three metrics: fluency (speaking smoothness),accuracy (word pronunciation correctness), and clarity(overall intelligibility). The system aggregates these into an overall proficiency score that tracks improvement over time. Scores are calculated immediately after each exercise, with historical data used to identify trends and adjust difficulty accordingly.

Why Pronunciation Matters
Clear pronunciation isn't just about sounding "native"; it's about being understood. When you pronounce words correctly, communication becomes easier, job interviews go smoother, and everyday interactions feel more natural and confident.
Many English learners struggle because they don't get enough feedback on their pronunciation. Traditional classes may only offer occasional correction, and self-study lacks the immediate feedback needed to identify and fix mistakes quickly.
DictaLearn fills this gap by providing instant, detailed feedback on every practice session. You know exactly how you're doing and what to improve, with no guesswork and no waiting for a teacher.
Our Approach
AI-Powered Feedback
Advanced speech recognition analyzes your pronunciation in real-time, providing detailed scores on fluency, accuracy, and clarity. This immediate feedback helps you adjust and improve faster.
Adaptive Learning
The platform adjusts difficulty based on your performance, ensuring you're always challenged but never overwhelmed. As you improve, content gets harder. If you struggle, it adapts to help you build confidence.
Multiple Practice Modes
Three distinct modes target different skills: Read Aloud for pronunciation, Repeat Audio for fluency and accent matching, and Type Audio for listening comprehension. Together, they provide comprehensive practice for all aspects of spoken English.
Privacy-First Design
Your voice data is processed securely and never permanently stored. Free users benefit from browser-based processing, while Pro users get server-side analysis with immediate deletion after scoring.
