SpeakFlow - Master Fluent English Speaking with AI
"Tired of listening to countless hours of English but still can't speak fluently?"
"Feeling unconfident, unsure if your pronunciation is correct?"

For every English learner facing these challenges, a new solution is here.
SpeakFlow is a next-generation training app specializing in shadowing, powered by state-of-the-art AI voice recognition technology.

What is Shadowing?
Shadowing is a powerful language training method where you listen to English audio and repeat it like a shadow, just a moment behind the speaker. It's a highly effective way to improve both your listening and speaking skills simultaneously—a technique practiced even by professional interpreters.

A New Learning Experience with SpeakFlow
Traditional shadowing has one major drawback: you never know if your pronunciation is accurate. SpeakFlow solves this problem with AI technology.

Key Features
1. Real-Time Pronunciation Scoring by AI
As you shadow, our AI transcribes your voice in real time. It then compares your speech to the native speaker's audio and evaluates your pronunciation with an objective score. Instantly see which words you've mastered and where you need to improve. Say goodbye to guesswork and practice with precision.

2. Master Difficult Phrases with AB Loop Repetition
Struggling with a specific phrase? The AB Loop feature is here to help. Repeatedly play and practice only the parts you find difficult, allowing you to focus your efforts and master them effectively.

3. Diverse Learning Content via Import
Import and practice with a wide range of audio content tailored to your goals—from practical business phrases and daily conversations to news and materials for TOEIC® & TOEFL® test preparation. Keep your learning journey fresh and engaging.

4. Visualize Your Progress
Track your daily training results and score trends with easy-to-read graphs. Seeing your improvement visually will keep you highly motivated.

Recommended for:
- Those who want to improve their speaking skills, especially fluency and pronunciation.

- Students aiming for high scores on standardized tests like TOEIC® or TOEFL®.

- Individuals preparing for studying abroad, overseas assignments, or international business trips.

- Professionals who want to acquire persuasive English for business situations.

- Learners who haven't seen results from listening-only practice.

- Anyone feeling they've hit a wall in their self-study journey.
