Sound familiar?

Your English is good. Your American accent can be, too.

Four problems many adult learners of English face every day.

People ask you to repeat yourself.

Your words are right, but listeners miss them the first time.

InPronunci: Interactive accent training places you in a student-centered, active role, so you practice speaking clearly instead of only listening.

You practice, but your accent stays the same.

Repeating after a recording does not train your speech organs or change your pronunciation.

InPronunci: Cognitive Accent Training, built into InPronunci, helps you understand how each sound is made, so you change the sound itself, not just the score.

You don't know what your tongue and lips should do.

Without that, every new sound is a guess.

InPronunci: Interactive Visual 2D Sound Simulators train your tongue, lips, and jaw for each American sound.

You feel nervous in meetings and on calls.

You know what to say, but not how it will sound.

InPronunci: Prof. Alex's step-by-step Pronunci Instruction guides you from single sounds to sentences and paragraphs, so you speak fluently and confidently in meetings and on calls.

You are not alone, and each of these can be trained.

Practice Mode and Evaluation Mode

How InPronunci Works: Interactive American Accent Training, Step by Step

InPronunci is built on the Interactive General American Pronunciation Training, also called Interactive American Accent Training, developed by Prof. Alex, Ph.D. Accent Coach, Doctor of Education, and professional linguist. It is not traditional pronunciation scoring. In Practice Mode, students train each American sound, then use it in phonetic exercises, sentences, and paragraphs. In Evaluation Mode, the AI Accent Coach gives feedback as they speak.

Every exercise places students in an active position: they listen, speak, compare My Coach with My Pronunci, correct, and retrain. Step by step, they build English pronunciation, intonation, rhythm, and connected speech, and become independent, confident English speakers.

Step 1

Develop Each American Sound Before Your Speech Practice

Start your American accent training with Sound Development, one sound at a time, in an English pronunciation app built around English sounds.

InPronunci app screen: American Unvoiced Sound [t] with the 2D Sound Motion Simulator

Hear It. Feel It. Train It. Practice It.

In Sound Development, learners train with the Interactive Visual 2D Sound Simulator for each target American sound, including American vowels and consonants.

The simulator trains the speech organs, including tongue position, lips, jaw, airflow, and voice, with guided voice-over instruction.

Students listen, train, and repeat the sound several times before moving into practice exercises. This helps build stronger control before evaluation begins.

Step 2

Practice the Sound in Phonetic Exercises

Use pronunciation exercises to build steady sound control and improve pronunciation word by word.

InPronunci app screen: Phonetic Exercise 1, [t] at the beginning of the word

From Sound Control to Word Practice

After Sound Development, learners practice the target sound in carefully selected words to build accurate American English pronunciation.

This helps the sound become more accurate, steady, and easier to use in speech.

The goal is not only to know how the sound works, but to train the sound until it begins to feel more natural.

Step 3

Evaluate Each Sound Before Full Sentences

One sound at a time, learners record the target American sound and receive AI Accent Coach feedback on their pronunciation before moving into full sentence practice.

InPronunci app screen: Phonetic Exercise 1, [t] at the beginning of the word, Evaluation and Feedback for the word Ten with a 75.52% score

Hear It. Try It. Compare It. Retrain It.

The AI Accent Coach focuses on one American sound, scores your pronunciation, and helps you compare your recording with the native-speaker model.

You can listen again, record again, and repeat until the sound becomes clearer and more controlled.

This supports Cognitive Accent Training because learners are not only receiving a score. They are listening, comparing, correcting, and retraining the sound with awareness.

Step 4

Practice the Sound, Intonation and Melody in Sentences

Practice the sound and American intonation inside real sentence structure.

InPronunci app screen: Practice Sentences, American [t] and [d] consonants

Guided Sentence Practice with English Intonation

Practice sentences help learners use the target sound inside real speech structure, including rising and falling intonation.

Listen to Pronunci gives guided instructions before practice, helping students focus on pronunciation, English rhythm, sentence stress, intonation, and connected speech.

This prepares learners for clearer and more natural American speech before they move into evaluation.

Step 5

Evaluate Your American Intonation & Connected Speech

Now the AI Accent Coach listens to the full sentence — not just the sound.

InPronunci app screen: Practice Sentences, American unvoiced [t] consonant, Evaluation and Feedback for the sentence Thomas missed the last train to town, with a 66.42% overall match

Intonation + Connected Speech Evaluated Together

After sound practice, learners evaluate the target sound inside real sentences. The AI Accent Coach checks pronunciation, rhythm, stress, intonation, and connected speech together.

Students compare My Coach with My Pronunci, their own recording, so they can hear the difference between the native-speaker model and their current speech pattern.

This helps learners build speaking clarity, listening awareness, and more natural American speech flow and intonation patterns.

Step 6

Practice Your Speech in Paragraphs for Public Speaking, Meetings, and Business Calls

Train longer speech, storytelling, and connected speech to speak English fluently and confidently.

Paragraph Practice for Real Speaking

With regular paragraph practice, the new pronunciation becomes your natural way of speaking, not something you have to think about.

You build strong public speaking skills and presentation-style delivery.

You become an independent, confident English speaker who can communicate across different topics and real-life situations.

Step 7

Evaluate Your Paragraph Speech

The AI Accent Coach evaluates the whole paragraph, word by word.

InPronunci app screen: Paragraph Practice, American short [ʊ] vowel, Evaluation and Feedback with a 34.76% score and color-coded paragraph

Paragraph Evaluation for Real Speech

After paragraph practice, learners record the full paragraph. The AI Accent Coach evaluates pronunciation, rhythm, stress, intonation, and connected speech across the whole paragraph, testing your intonation and pronunciation like a full English accent test for longer speech.

Each word is color-coded, so students can hear which words and sounds still need work. They compare My Coach with My Pronunci to hear the difference.

The score shows how close the paragraph is to native-speaker speech (100 = native speaker).

Step 8

Review Your Feedback from Paragraphs to Sentences to Words and Word Combinations to Sounds

Real sentence pronunciation — not dictionary pronunciation. View Feedback gives detailed feedback on fluent speech for students whose goal is to speak like a native.

InPronunci app screen: Feedback and Analysis after paragraph evaluation, sound-by-sound scores for Like A Rook

Real Sentence Pronunciation, Not Dictionary Audio

After each evaluation, View Feedback breaks the paragraph into sentences, sentences into words and word combinations, and words into sounds.

Students hear how native speakers actually say each part in fluent American speech, with sounds that connect, reduce, and change.

This helps students develop independent speaking habits in rapid speech and become confident speakers of American English with an accent coach and accent training app built for real fluent speech.
