Frequently Asked Questions

Yes! Unlike other apps that use the same curriculum for all learners, soundperfect is built from the ground up for Korean and Japanese speakers. We understand your specific challenges:

• L/R distinctions - Why Korean ㄹ and Japanese ラ don't match English sounds
• TH sounds - Techniques for /θ/ and /ð/ that don't exist in your language
• Consonant clusters - Managing combinations like "str" and "spr"
• Stress patterns - English rhythm that differs from syllable-timed languages
• Long vowel sounds - Distinctions like ship/sheep that matter for comprehensibility

Absolutely! soundperfect starts at the very beginning, unlike other apps that assume advanced vocabulary. Our approach:

• Basic vocabulary first - We teach pronunciation using simple, everyday words
• Step-by-step progression - Each lesson builds on the previous one
• Visual guides - Mouth and tongue position illustrations for every sound
• IPA symbol explanations - Learn the "alphabet" of pronunciation

Many of our most successful users started as complete beginners!

soundperfect provides what YouTube videos can't:

• Personal feedback - Advanced AI analyzes YOUR pronunciation and tells you exactly what to improve
• Structured progression - Research-based 365-day curriculum vs. random video browsing
• Real-time guidance - Immediate feedback as you practice, not just passive watching
• Progress tracking - See your improvement over time with detailed analytics
• Consistent quality - Every lesson follows the same proven methodology

Think of YouTube as inspiration, but soundperfect as your personal pronunciation coach.

Research shows that 15 minutes of focused daily practice is more effective than sporadic longer sessions. Here's why:

• Muscle memory development - Pronunciation requires training your mouth muscles, which develops best through consistent short practice
• Prevents fatigue - Your mouth and brain get tired, making longer sessions less productive
• Habit formation - 15 minutes is sustainable daily, creating lifelong pronunciation improvement habits
• Optimal attention span - Focused pronunciation practice requires intense concentration

You can always practice more, but our curriculum is designed around this optimal window.

Functional load measures how much a pronunciation error affects listener comprehension. We prioritize errors with the highest impact first.

High functional load example: L/R confusion affects hundreds of word pairs (light/right, play/pray, glass/grass), making it critical for comprehensibility.

Low functional load example: Some vowel distinctions might only affect a few word pairs, so we teach them later.

This research-based approach means you see dramatic improvement faster by focusing on what matters most for being understood.

Our goal isn't to eliminate your accent—it's to make you clearly understood and confident. Here's what we focus on:

• Comprehensibility - Being easily understood by native speakers
• Confidence - Feeling comfortable speaking in professional and social situations
• Reduced errors - Minimizing pronunciation mistakes that cause confusion
• Natural rhythm - Developing English stress and intonation patterns

Many users find their accent naturally lightens as their pronunciation improves, but our priority is clear, confident communication.

We use professional-grade speech analysis technology that provides:

• Phoneme-level accuracy - Analysis of individual sounds within words
• Word stress evaluation - Detection of emphasis patterns
• Fluency metrics - Speaking rate and pause analysis
• Real-time pitch tracking - Visual feedback on your intonation
• Error identification - Specific feedback on missed, added, or substituted sounds

The same technology is used by pronunciation researchers and language assessment companies worldwide.

Typical timeline:

• Week 1: Better awareness of your pronunciation patterns
• Week 2-4: Noticeable improvement in target sounds (L/R, TH, etc.)
• Month 2-3: Friends and colleagues start commenting on clearer speech
• Month 6-12: Significant confidence improvement in professional situations

Remember: Pronunciation is like physical exercise - consistent daily practice creates lasting muscle memory. Some sounds improve quickly, others take patience.

Don't worry! Missing occasional days won't ruin your progress:

• Built-in flexibility - Our curriculum accounts for real life
• Smart catch-up - The app suggests how to get back on track
• Progress retention - Pronunciation skills stay with you even after breaks
• No guilt trips - We encourage consistency but understand life happens

Pro tip: Try to practice at least 4-5 days per week for optimal results. Weekend breaks are totally fine!

This is completely normal! Pronunciation improvement isn't linear:

• Muscle memory takes time - Your mouth needs to learn new movement patterns
• Mistakes are part of learning - Even advanced speakers occasionally slip back to old patterns
• Focus on trends - Are you making fewer mistakes than last month? That's progress!
• Automatic vs. controlled speech - New sounds work in practice first, then gradually transfer to natural conversation

Trust the process - consistent practice always leads to improvement, even when it doesn't feel like it day-to-day.
