About

AccentForge

Features
Read full description

AccentForge is a real-time accent coaching app for non-native English speakers who want to sound clearer and more confident in American English. Unlike apps that analyse recordings after the fact, AccentForge listens and responds live — the same way a human coach would. Speak naturally and receive immediate, specific feedback on your pronunciation, rhythm, and intonation. --- WHAT ACCENTFORGE COACHES --- - Rhotic R — the most distinctively American sound - TH sounds (voiced and unvoiced) — "this" vs "think" - Flap T — the way Americans say "butter" and "water" - Vowel shifts — how American vowels differ from British, Indian, Spanish, Mandarin, and other accents - Intonation and prosody — the music of American speech - Linking and reduction — how words flow together in natural speech --- HOW IT WORKS --- 1. Tap the mic to start a session 2. Speak naturally — introduce yourself, read the prompt, or have a conversation 3. Your AI coach listens and gives specific, encouraging feedback 4. Get a 1–10 accent score and targeted exercises to practice Your coach is an AI. Feedback is generated automatically — you get honest, consistent scores every session with no waiting and no scheduling. Coaching is personalised to your native language. Spanish speakers make different errors than Mandarin or Hindi speakers — AccentForge targets your specific interference patterns, not generic advice. --- WHO USES ACCENTFORGE --- - Software engineers, product managers, and tech leads presenting to US leadership or on international calls - Healthcare professionals — doctors, nurses, and pharmacists where clarity affects patient trust - MBA students, finance, and consulting professionals working in US firms - Customer success and support teams serving North American customers - Academics presenting research at US conferences and seminars - Students preparing for IELTS speaking, US university applications, or job interviews - Anyone who has Googled "how to sound more American", "how to reduce my accent", or "American pronunciation coach" --- FREE EVERY WEEK --- Every user gets 5 free coaching minutes per week — no account, no credit card, no commitment. Your balance resets every Sunday. One session a week is enough to build a measurable habit over time. When you're ready to accelerate: Learner gives you 40 minutes a month and full session history. Fluent gives you 90 minutes a month and native-language-aware coaching tailored to your background. --- PRIVACY FIRST --- AccentForge does not require an account, email address, or any personal information. A random identifier is created on your device to track your session history. Audio is never stored -it is processed live and discarded immediately. --- WHY ACCENTFORGE --- Unlike subscription-only alternatives charging $20–25/month with no free option, AccentForge starts completely free. Use it once a week forever, or upgrade when you're ready to push harder. Unlike apps that drill you with isolated word lists or analyse recordings after the fact, AccentForge responds in real time — you speak naturally, and your coach replies with specific feedback on exactly what to adjust and how. Native-language-aware coaching is the core difference. AccentForge knows that a Mandarin speaker's vowel shifts are different from a Spanish speaker's rhythm patterns, and different again from a Hindi speaker's consonant placements. Every session targets what matters for your background. Your accent doesn't need to disappear — it needs to become clear. AccentForge gives you the feedback to get there. --- LEGAL --- Privacy Policy: https://kernelcraft.com/privacy-policy-accentforge/ Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
