PronouncePro

A serious English pronunciation correction app designed at the phoneme level for Japanese speakers.

The AI ​​mercilessly identifies "intelligible pronunciation" and "unintelligible pronunciation."

【What you can do】

🎤 AI Pronunciation Scoring
Visualizes the difference from the example at the phoneme level (R/L/TH/V, etc.). Highlights words that sounded different in yellow and immediately points out the reason why it wasn't understood. Also assesses the achievement of linked pronunciation (liaison), such as "Want to" becoming "Wanna." Get closer to a natural, native sound.

📈 Difficult Sound Dashboard
Scores for each phoneme accumulate with each score. You can see how many times you practiced and what score you reached (e.g., "R (15 practice sessions)"), allowing you to feel your improvement.

📚 Systematic Courses
Learn native pronunciation at different levels (Beginner/Intermediate/Advanced), including basic linking, function word reduction, and intonation.

🗣 Situation-Based & Pattern-Based Phrases
Master phrases from both situation-based formats (office, airport, hotel, cafe, etc.) and pattern-based formats ("Could you...", "Would you mind...", etc.).

🎯 Over 200 Native Idioms
Practice expressions truly used by native speakers, categorized by phrasal verbs and idioms.

💭 Situational Conversation Listening
Improve your listening skills by progressing through realistic conversations such as ordering at a bar, negotiating returns, and checking into a hotel, using a step-by-step approach: "Hide → One Person at a Time → Full Text".

✍️ Instant English Composition
Translate Japanese sentences into English instantly. Supports both text input and voice (microphone). AI provides a 5-point rating ("Almost There / Good / Perfect") and suggests natural phrasing.
