Pronunciation Lab — Sound Like America
A complete American pronunciation curriculum from A1 to C1: individual sounds, word stress, sentence stress, rhythm, intonation — and the connected speech Americans actually use. 26 lessons, every one built on the same loop: notice, listen, compare, repeat, shadow.
The journey
How every lesson works
Notice the feature. Listen to the AI model — natural speed, then slow. Notice the difference between careful and natural pronunciation. Repeat out loud and record yourself. Compare your recording with the model using the self-check list — no fake scores, ever. Then shadow: speak with the voice, half a second behind it.
A note on spoken forms: spellings like gonna, wanna and lemme in this lab are representations of spoken pronunciation, not standard spellings. Use them to understand and to sound natural in conversation — never in formal writing.
A1 — Foundations (5 lessons)
The sounds of English, one by one: vowels, consonants, syllables, and your first word stress — pronounced slowly and clearly.
Vowel Sounds — Short and Long
English vowels come in two lengths — short and quick, or long and stretched — and the length alone can change the word. Ship and sheep differ only in the vowel. Train the contrast here and hundreds of words become clearer. (Short vs long vowels: ship / sheep · bit / beat · full / fool)
OpenConsonant Sounds — Voiced and Voiceless
Many English consonants come in pairs made with the same mouth position: one is quiet (voiceless), one buzzes (voiced). Pat vs bat, ten vs den. And the final consonant of a word is precious — drop it, and the word changes or vanishes. (p/b · t/d · k/g — and why final consonants matter)
OpenDifficult Sounds — TH, R/L, W/V
Three sounds cause trouble for learners from almost every language: TH (think, this), the R/L contrast (red, led), and W/V (west, vest). Each one is a simple mouth position — learn the position and the sound follows. (The three classic trouble spots for learners worldwide)
OpenSyllables — Counting the Beats
English words are built from beats called syllables: 'cat' has 1, 'table' has 2, 'banana' has 3. Every syllable contains exactly one vowel sound. Counting beats is the first skill behind word stress — and behind clear pronunciation. (Every word has beats — learn to count them)
OpenWord Stress Basics — the Strong Syllable
In every English word with more than one syllable, ONE syllable stands out: louder, longer, and clearer. The others relax. Stress is not decoration — 'DOCtor' with the stress moved sounds wrong even if every sound is right. (One syllable is louder, longer, clearer — find it)
OpenA2 — Contrasts & Word Stress (5 lessons)
Train your ear to hear the difference: minimal pairs, vowel and consonant contrasts, syllable counting, and where the stress falls.
Minimal Pairs — Vowel Contrasts
A minimal pair is two words that differ by ONE sound. English is full of vowel pairs where only the length and tension of the vowel changes — and learners merge them into one. This lesson separates the six most useful pairs, first in isolation, then in real sentences. (ship/sheep · live/leave · bit/beat · full/fool · sit/seat · pull/pool)
OpenMinimal Pairs — Consonant Contrasts
Now the consonants. Six contrasts that learners merge every day: the buzz at the end of 'rise', the lip-teeth of 'van', and the famous TH that hides inside 'thin' and 'think'. Hear them, separate them, say them. (rice/rise · fan/van · thin/sin · think/sink · cheap/sheep · day/they)
OpenWord Stress Patterns — Families and Job-Changers
Stress MOVES. In word families it jumps as suffixes arrive: PHOtograph, phoTOGraphy, photoGRAphic. And a small group of two-syllable words changes its job with stress: a REcord is a thing; to reCORD is an action. Learn to hear — and place — the moving beat. (PHOtograph → phoTOGraphy · a REcord vs to reCORD)
OpenCan vs Can't — Stress Carries the Meaning
The most misunderstood pair in American English. In 'I can go', the word 'can' almost vanishes — a quick, weak 'kən'. In 'I can't go', 'can't' is loud and strong. Americans don't listen for the final 't' (often it's barely there) — they listen for the STRESS. (Positive 'can' shrinks; negative 'can't' stays strong)
OpenEveryday Words Americans Shorten
Open a dictionary and 'comfortable' has four syllables. Listen to an American and it has three. Many everyday words quietly lose a middle syllable in natural speech — and if you say every syllable, you sound like a spelling bee, not a speaker. (comfortable · vegetable · chocolate · Wednesday · family)
OpenB1 — Natural Sentence Pronunciation (6 lessons)
Sentences are music, not word lists: the schwa, sentence stress, rhythm, intonation, linking, thought groups, and weak forms.
The Schwa — the Most Common Sound in English
Meet the schwa: /ə/, a tiny relaxed 'uh'. It is the most common vowel in English, and it can be spelled by ANY vowel letter — the a in about, the e in teacher, the o in lemon, the a in sofa. Master the schwa and your English instantly gains its natural rhythm. (/ə/ — the lazy 'uh' hiding in almost every sentence)
OpenSentence Stress — Content Words Carry the Message
Native speakers do NOT pronounce every word with equal strength. In 'I WANT the RED one', two words tower over the rest. Content words (nouns, main verbs, adjectives, adverbs) get the stress; function words (the, a, to, and) shrink. Learn this and both your listening and your speaking jump a level. (Stress nouns, verbs, adjectives — shrink the little words)
OpenRhythm & Thought Groups
English rhythm is stress-timed: the strong beats land at regular intervals like a drum, and the small words between them squeeze to fit — fast or slow depending on how many there are. Speech also travels in thought groups: short chunks of meaning with tiny pauses between them. (Stress-timed beats + speaking in meaning chunks)
OpenIntonation Basics — the Melody of English
Words carry grammar; melody carries attitude. A falling tone says 'finished, certain' — statements and WH-questions. A rising tone says 'open, checking' — yes/no questions and surprise. Same words, different melody, different meaning: 'You're coming.' vs 'You're coming?' (Falling = finished · Rising = open · Lists rise, then fall)
OpenLinking — Connect Consonant to Vowel
English words in speech are not islands. When a word ends in a consonant and the next word begins with a vowel, the consonant jumps across and joins the next word: 'turn off' sounds like 'tur-noff', 'an apple' like 'a-napple'. This is linking — the glue of natural American speech. (turn off → tur-noff · pick it up → pi-ki-tup)
OpenWeak Forms — to, for, and, of, can in Sentences
About forty small English words have two pronunciations: a STRONG form (dictionary, alone, stressed) and a WEAK form (inside sentences). 'To' is 'too' alone — but 'tə' in 'I have to go'. 'For' becomes 'fer', 'and' becomes 'ən', 'of' becomes 'əv'. Native speech is built from weak forms. (The strong/weak double life of little words)
OpenB2 — American Connected Speech (5 lessons)
How Americans really connect speech: the American R, the flap T, reductions like gonna and lemme, advanced linking, and natural contractions.
The American R — the Sound of America
The single most American sound: a strong, growling R that is ALWAYS pronounced — at the start, middle, and end of words. British-style English drops R after vowels; American English keeps every one: car, hard, teacher, four, here, care. If you want to sound American, start here. (Rhotic R: car, hard, teacher, four — R is always pronounced)
OpenThe Flap T — America's Favorite Sound
Between vowels, American T turns into a quick flap of the tongue — a sound so fast it resembles a soft D. Water becomes 'wah-der', city becomes 'ci-dee'. This flap T is everywhere in American speech, and hearing it (then using it) transforms both your listening and your accent. (water → wah-der · city → ci-dee · better · little · party)
OpenReductions — gonna, wanna, gotta, lemme & Friends
The seven most useful reductions in American English. In natural conversation, 'going to' melts into 'gonna', 'let me' into 'lemme'. You need these first for LISTENING — Americans use them constantly — and then, carefully, for relaxed speaking. (going to → gonna · want to → wanna · got to → gotta · give me → gimme · let me → lemme · kind of → kinda · sort of → sorta)
OpenAdvanced Linking — Glides, Merges & Smooth Chains
Beyond consonant-to-vowel linking lies the second layer: when two VOWELS meet across words, Americans insert a tiny glide — /w/ after 'oo/oh' sounds, /j/ after 'ee/ay' sounds — and heavy consonant clusters simplify. This is what makes fast speech sound like one long word. (go on → go-won · I agree → I-yagree · next day → nex-day)
OpenContractions in Fast Speech — I'd've, That'd, What'll
Every learner knows I'm and don't. Fast American speech goes further: 'I would have gone' compresses to 'I'd've gone', 'That would be' to 'That'd be'. You will hear these daily — this lesson makes them visible, then lets you practice the safe, common ones. (I would have → I'd've · that would → that'd · what will → what'll)
OpenC1 — Advanced Natural American Speech (5 lessons)
Expressive pronunciation: contrastive stress, attitude in intonation, fast-speech reductions, discourse rhythm, and shadowing at full speed.
Contrastive Stress — Stress IS the Meaning
At C1, stress stops being decoration and becomes vocabulary. Moving the main stress to a different word corrects, insists, or accuses — without changing a single word. 'I didn't say HE took it' has seven words, and stressing each one produces seven different meanings. ('I wanted the RED one' vs 'I WANTED the red one' — one stress, new message)
OpenIntonation & Attitude — Polite, Firm, Warm, Doubtful
Native listeners judge your attitude from melody before they process your words. 'Okay.' can be warm agreement, cold dismissal, or open doubt. At C1 you learn to hear — and choose — those melodies: certainty falls cleanly, uncertainty hovers, politeness softens the edges, and firm disagreement stays level and unhurried. (The same words, four attitudes — melody is the message)
OpenFast-Speech Reductions — didja, whaddaya, jeet
At full speed, Americans compress whole phrases into single beats: 'Did you…?' becomes 'Didja…?', 'What do you want?' becomes 'Whaddaya want?', and 'Did you eat yet?' becomes the famous 'Jeet yet?'. Your goal at C1: understand every one instantly. Producing them is optional, casual-only seasoning. (The deep end of connected speech — understand everything, produce carefully)
OpenDiscourse Prosody — Sounding Confident in Long Turns
In presentations, interviews, and meetings, pronunciation scales up: you must organize MINUTES of speech so listeners can follow. Discourse prosody is the architecture — chunking into thought groups, stressing new information, dropping pitch to close a point, and lifting it to open the next one. (Chunking, signposting, and pitch architecture for talks and interviews)
OpenThe Shadowing Studio — Train Like an Interpreter
Shadowing is the closest thing pronunciation training has to a full workout: you speak WITH the model voice, half a second behind it, copying its rhythm, reductions, linking, and melody exactly. Interpreters train this way. Fifteen focused minutes beats an hour of casual repetition. (The complete protocol: blind listen → mark → shadow ×3 → hide text → record & check)
