Assimilation, elision, and AmE reductions

You’ve now built the connected-speech foundation: weak forms, linking, glides. This lesson covers the next layer — what happens when sounds change (assimilation), disappear (elision), or collapse into casual forms like gonna and wanna.

These features are 100% standard in spoken AmE. You must recognize them in listening — without that, half of native conversation is incomprehensible. You may produce the casual forms in informal speech, but never write them in formal contexts.

Assimilation — when one sound changes another

Assimilation is when one sound shifts to be more similar to a neighboring sound, usually because it’s mechanically easier. The /t/ + /j/ combination across a word boundary is the classic AmE example.

/t/ + /j/ → /tʃ/ (“ch”)

When a word ends in /t/ and the next word starts with /j/ (most often the y in you, your, yet), the two sounds fuse into /tʃ/.

/d/ + /j/ → /dʒ/ (“j”)

Same principle for /d/.

/s/ + /j/ → /ʃ/ (“sh”)

/z/ + /j/ → /ʒ/ (“zh”)

Drill: /t/, /d/ + you

Read each casually:

1. Did you go? → /dɪdʒə ɡoʊ/
2. Would you mind? → /wʊdʒə maɪnd/
3. Don’t you want it? → /doʊntʃə wɑːnt ɪt/
4. I’ll meet you there. → /aɪl miːtʃə ðer/
5. What’s your name? → /wɑːtʃər neɪm/
6. Could you help me? → /kʊdʒə help mi/
7. Got you! → /ɡɑːtʃə/ (= “gotcha”)
8. I miss you. → /aɪ mɪʃu/
9. Where did you go? → /wer dɪdʒə ɡoʊ/
10. Bless you. → /bleʃu/

Elision — when sounds disappear

Elision is when a sound is dropped entirely, usually to make a difficult consonant cluster easier.

/t/ and /d/ between consonants

Probably the most common elision. When /t/ or /d/ sits between two other consonants, it disappears.

/h/ in unstressed pronouns

Already covered in lesson 04. Quick recap: he, him, her, his, has, had, have lose /h/ when unstressed mid-sentence.

Drill: elision in connected speech

1. I went last night. → /aɪ went læs naɪt/
2. Send me a postcard. → /sen mi ə ˈpoʊskɑːrd/
3. Mostly cloudy. → /ˈmoʊsli ˈklaʊdi/
4. Next time. → /neks taɪm/
5. Christmas Eve. → /ˈkrɪsməs iv/
6. He didn’t see me. → /hi dɪdn̩ si mi/
7. Tell him to wait. → /tel ɪm tə weɪt/
8. Give her this. → /ɡɪv ər ðɪs/
9. I asked her. → /aɪ æst ər/ (or /æskt ər/)
10. Just facts. → /dʒəs fæks/

AmE-specific reductions: gonna, wanna, gotta and friends

These are whole-phrase reductions that have become standard casual AmE. Each starts as a two- or three-word phrase and collapses into a single fused unit.

The core list

Important rule: gonna only for future intent

Going to has TWO meanings:

1. Future intent (I’m going to study tonight) → can become gonna: /aɪm ˈɡənə ˈstʌdi təˈnaɪt/.
2. Movement to a place (I’m going to the store) → CANNOT become gonna. You must say I’m going to the store with full to.

Same for want to:

• I want to leave (desire + verb) → I wanna leave /aɪ ˈwɑːnə liv/.
• I want two of those (desire + number “two”) → CANNOT reduce. Two is a content word.

The rule: reduction only happens when to is the infinitive marker before a verb, not when it’s a real preposition + noun.

Drill: AmE reductions

Read each casually:

1. I’m gonna call him later. → /aɪm ˈɡənə kɔː lɪm ˈleɪɾər/
2. Do you wanna come? → /də jə ˈwɑːnə kʌm/
3. I gotta go. → /aɪ ˈɡɑːɾə ɡoʊ/
4. We hafta finish by Friday. → /wi ˈhæftə ˈfɪnɪʃ baɪ ˈfraɪdeɪ/
5. You usta live here, right? → /jə ˈjuːstə lɪv hɪr raɪt/
6. I’m supposta be there at ten. → /aɪm səˈpoʊstə bi ðer ət ten/
7. It’s kinda cold. → /ɪts ˈkaɪndə koʊld/
8. That’s sorta what I meant. → /ðæts ˈsɔːrɾə wʌt aɪ ment/
9. Get outta here! → /ɡe ˈɾaʊɾə hɪr/
10. I dunno. → /aɪ dəˈnoʊ/
11. Whatcha doing? → /ˈwʌtʃə ˈduːɪŋ/
12. Lemme see. → /ˈlemi si/
13. Gimme a minute. → /ˈɡɪmi ə ˈmɪnət/
14. I shoulda known. → /aɪ ˈʃʊdə noʊn/
15. We coulda gone. → /wi ˈkʊdə ɡɔːn/

When NOT to use these reductions

There’s a clear style line:

Style examples

Wrong (writing): I wanna apply for the position because I think I’m gonna be a great fit.

Right (writing): I want to apply for the position because I believe I would be a great fit.

Wrong (job interview): Yeah, I’m kinda interested. I gotta think about it.

Right (job interview): Yes, I’m very interested. Let me consider the offer.

OK (text to friend): gonna grab coffee, wanna come?

OK (movie subtitles): I’m gonna kill him.

/h/ elision summary table

The /h/ disappears in unstressed pronouns/auxiliaries when they follow another word in connected speech.

But /h/ STAYS at the start of a phrase or sentence:

• He went home — /h/ pronounced.
• Have you seen him? — initial /h/ pronounced; second /h/ in him dropped: /hæv jə si nɪm/.

AmE vs BrE notes

The flap T inside gotta and sorta is what makes them sound American, not British.

Common Russian-speaker mistakes

1. Pronouncing every sound clearly because “that’s correct”. Did you /dɪd ju/ instead of /dɪdʒə/. Sounds rehearsed and over-careful. Native AmE assimilates.
2. Writing gonna, wanna, gotta in formal email. Job application: I gotta tell you I wanna work here. — instant rejection. Reserve for casual conversation.
3. Reducing to when it shouldn’t reduce. I’m gonna the store — wrong. Reduction only with infinitive to + verb.
4. Pronouncing /h/ in him, her mid-sentence. Already covered, still common: tell HIM with sharp /h/. Drop it: /tel ɪm/.
5. Pronouncing /t/ in Christmas, postman, mostly. /ˈkrɪstməs/ instead of /ˈkrɪsməs/. Drop the /t/.
6. Hearing gonna and not understanding it. This is the listening trap. Train your ear to recognize the reduced forms; they appear constantly in real speech, not just in fiction.
7. Avoiding the casual reductions out of “respect” for English. Reductions ARE English — they’re not slang or laziness. Using them appropriately makes you sound competent.

Summary

• Assimilation: /t/+/j/ → /tʃ/ (want you → /wɑːntʃu/), /d/+/j/ → /dʒ/ (did you → /dɪdʒə/).
• Elision: /t/ and /d/ disappear between consonants (next day, last night, Christmas); /h/ drops in unstressed pronouns (tell him → /tel ɪm/).
• AmE reductions: gonna, wanna, gotta, hafta, kinda, sorta, lemme, gimme, dunno, whatcha, shoulda/woulda/coulda. Recognition mandatory; production casual-only.
• NEVER write the casual reductions in formal contexts.
• Gonna only for future intent + verb; wanna only for desire + verb; not when to/two is a real noun.
