Sounds That Change
The sound is still there, just different. This is the biggest group — the story of how T transforms in American English, plus other sound changes.
Flap T/D ↑
When T or D sounds like a quick tap
What is it?
In American English, T and D often become a quick flap sound [ɾ] — like a very fast D, or the "tt" in Spanish "gato".
butter
→
/bʌtər/
→
[bʌɾər]
This is why "butter" and "budder" sound the same, and "writer" and "rider" are nearly identical.
When does it happen?
Flapping occurs when T or D is:
- After a vowel or R
- Before an unstressed vowel or syllabic L
**Key:** The following syllable must be *unstressed*. That's why "atomic" keeps its T (stress on second syllable), but "atom" flaps it.
Examples
T between vowels
butter · water · better · letter · later · matter · city · pretty
T after R
party · forty · thirty · dirty · quarter
T before syllabic L
little · bottle · battle · settle · metal
D also flaps
ladder · lady · ready · body · study · nobody
Homophones
Because of flapping, these word pairs sound identical:
| With T |
With D |
| writer |
rider |
| latter |
ladder |
| metal |
medal |
| batting |
badding |
| bitter |
bidder |
Exceptions
- Before stressed vowels: atomic, attack, guitar — no flap because stress follows
- After N: button, kitten, mountain — uses glottal stop instead
- Word-initial T: top, time, table — always full T
- Careful/formal speech: Some speakers avoid flapping in formal contexts
Cross-word flapping
Flapping also happens between words in connected speech. When a word ends in T and the next word starts with a vowel, they link together with a flap.
lot of
→
/lɑt ʌv/
→
[lɑɾə]
Common phrases
but I · what I · get out · put it · about it · lot of
**Note:** Punctuation blocks flapping. Compare "but I" [bʌɾaɪ] vs "but, I" [bʌt aɪ].
Glottal Stop + Syllabic N ↑
When T becomes a catch in your throat
What is it?
In words like button and kitten, the T becomes a glottal stop [ʔ] — a brief catch in your throat, like the sound in "uh-oh".
button
→
/bʌtən/
→
[bʌʔn̩]
The schwa vowel is also dropped, making the N syllabic — it forms its own syllable without a vowel.
When does it happen?
This pattern occurs when:
- T comes after a vowel (or R)
- T is followed by unstressed -en or -on
**Note:** This is different from [flapping](/rules/flapping/). After N, T becomes a glottal stop, not a flap. Compare: "butter" [bʌɾər] vs "button" [bʌʔn̩].
Examples
Common -ton/-ten words
button · kitten · cotton · mitten · written · bitten · rotten · gotten
Longer words
forgotten · Manhattan · Britain · mountain · fountain · certain · curtain
How to pronounce it
- Say the first part of the word normally ("but-")
- Stop your airflow briefly in your throat (like holding your breath)
- Release directly into N — no vowel between the glottal stop and N
**Practice:** Try saying "uh-oh" — the break between "uh" and "oh" is a glottal stop. Now use that same throat catch in "but-[ʔ]-n".
Related rules
- Syllabic N — N forming its own syllable (garden, sudden)
- Syllabic L — L forming its own syllable (bottle, little)
- Flap T/D — T becoming a tap (butter, water)
Glottal T (Word-Final) ↑
When T becomes a glottal stop before consonants
What is it?
When a word ends in T (not in a cluster), it often becomes a glottal stop [ʔ] before a consonant. A glottal stop is made by briefly closing your throat.
that boy
→
/ðæt bɔɪ/
→
[ðæʔ bɔɪ]
what time
→
/wʌt taɪm/
→
[wʌʔ taɪm]
When does it happen?
Glottal T occurs when:
- Word ends in T — not in a cluster like -st, -nt
- Next word starts with consonant — not a vowel
- In casual speech — very common in American English
**Note:** Before vowels, T usually becomes a flap [ɾ] instead (see Flap T/D rule).
Examples
| Phrase |
Standard |
Spoken |
| that boy |
ðæt bɔɪ |
ðæʔ bɔɪ |
| what time |
wʌt taɪm |
wʌʔ taɪm |
| get back |
ɡɛt bæk |
ɡɛʔ bæk |
Exceptions
- Before vowels: "that is" → T becomes flap, not glottal stop
- In clusters: "just say" → T is deleted (see Final T/D Elision)
- Careful speech: In formal contexts, T may be fully pronounced

Palatalization ↑
When "got you" becomes "gotcha"
What is it?
When T or D meets the Y sound in "you/your/yet", they merge into a new sound:
- T + Y → CH [ʧ] (gotcha)
- D + Y → J [ʤ] (didja)
got you
→
/ɡɑt ju/
→
[ɡɑʧu]
did you
→
/dɪd ju/
→
[dɪʤu]
When does it happen?
Palatalization occurs when:
- Word ends in T or D
- Next word starts with /j/ — usually "you", "your", "yet"
- In casual/fast speech — very common in everyday conversation
**Note:** This creates familiar casual spellings like **gotcha**, **didja**, **whatcha**, **wouldja**.
Examples
T + Y → CH [ʧ]
| Phrase |
Standard |
Spoken |
| got you |
ɡɑt ju |
ɡɑʧu |
| what you |
wʌt ju |
wʌʧu |
| let you |
lɛt ju |
lɛʧu |
| meet you |
mit ju |
miʧu |
D + Y → J [ʤ]
| Phrase |
Standard |
Spoken |
| did you |
dɪd ju |
dɪʤu |
| would you |
wʊd ju |
wʊʤu |
| could you |
kʊd ju |
kʊʤu |
Optional: S/Z + Y (fast speech only)
In very fast, casual speech, S and Z can also merge with Y. This is less common and more subtle than T/D palatalization.
**Note:** These are optional. Many speakers keep S/Z and Y separate even in casual speech.
S + Y → SH [ʃ] (optional)
| Phrase |
Standard |
Spoken |
| this year |
ðɪs jɪr |
ðɪʃ ɪr |
| miss you |
mɪs ju |
mɪʃ u |
Z + Y → ZH [ʒ] (optional)
| Phrase |
Standard |
Spoken |
| those years |
ðoʊz jɪrz |
ðoʊʒ ɪrz |
| as you |
æz ju |
æʒ u |
| was your |
wʌz jʊr |
wʌʒ ʊr |
| is your |
ɪz jʊr |
ɪʒ ʊr |
| has your |
hæz jʊr |
hæʒ ʊr |
Exceptions
- Careful/formal speech: Speakers may pronounce T/D and Y separately
- Slow speech: When speaking deliberately, the sounds stay distinct
- Emphasis: "Did YOU do it?" keeps the sounds separate

-ING Reduction ↑
When -ing becomes -in'
What is it?
In casual American English, the -ing ending is often pronounced as -in [ɪn] instead of [ɪŋ]. The "g" sound drops and the nasal changes from velar (back of mouth) to alveolar (front).
going
→
/ɡoʊɪŋ/
→
[ɡoʊɪn]
This is sometimes written as goin' or runnin' in informal writing.
When does it happen?
-ING reduction is common in:
- Casual conversation — everyday speech between friends
- Fast speech — when speaking quickly
- Regional dialects — more common in some regions
**Note:** This is a casual/informal pronunciation. In formal speech, job interviews, or presentations, speakers typically use the full [ɪŋ] sound.
Examples
Common verbs
going · running · coming · doing · playing · talking · working · thinking
Common phrases
What are you doin'? · I'm just sayin' · Keep on movin' · Nothing's happenin'
Important distinction
Don't confuse -ing words with words that end in -ing as part of the root:
- sing, ring, king — these don't reduce (they're not the -ing suffix)
- singing, ringing — these CAN reduce ("singin'", "ringin'")
Related rules
TH to N Assimilation ↑
When "in the" becomes "in-nuh"
What is it?
When "the" follows a word ending in /n/, the TH sound often assimilates (changes) to match the N, becoming another [n] sound.
in the
→
/ɪn ðə/
→
[ɪn nə]
This creates a smooth double-N sound: "in the" → "in-nuh".
When does it happen?
TH-to-N assimilation occurs when:
- Word ends in /n/ — in, on, an, been, when, then, etc.
- Followed by "the" — the most common word in English
- In fast/casual speech — very common in everyday conversation
**Note:** This makes speech flow more smoothly — the tongue doesn't have to move between N and TH positions.
Examples
| Phrase |
Standard |
Spoken |
| in the |
ɪn ðə |
ɪn nə |
| on the |
ɑn ðə |
ɑn nə |
| when the |
wɛn ðə |
wɛn nə |
Exceptions
- Careful/formal speech: TH may be pronounced distinctly
- Emphasis: "in THE box, not on it" — TH pronounced for contrast
- Slow speech: When speaking deliberately, sounds stay separate

Sounds That Disappear
More dramatic — the sound is just gone. From specific words like "of" and "them" to general patterns like schwa deletion.
V Elision in "of" ↑
When "of" loses its V sound
What is it?
In connected speech, the word "of" often reduces from /ʌv/ or /əv/ to just /ə/, completely dropping the /v/ sound. This is one of the most common reductions in English.
kind of
→
/kaɪnd ʌv/
→
[kaɪndə]
This is why "kind of" sounds like "kinda" and "sort of" sounds like "sorta".
When does it happen?
V elision in "of" occurs:
- In connected speech — when "of" follows another word without pause
- When unstressed — the word "of" is almost always unstressed
**Note:** When the preceding word ends in T or D, you often get **both** V elision AND [cross-word flapping](/rules/flapping/). That's why "lot of" becomes [lɑɾə] and "sort of" becomes [sɔrɾə].
Examples
Common phrases
kind of → kinda · sort of → sorta · lot of → lotta · out of → outta · because of · instead of
With cross-word flapping
When the word before "of" ends in T or D, you get flapping too:
| Phrase |
Phonemic |
Phonetic |
Spelled |
| sort of |
/sɔrt ʌv/ |
[sɔrɾə] |
sorta |
| lot of |
/lɑt ʌv/ |
[lɑɾə] |
lotta |
| out of |
/aʊt ʌv/ |
[aʊɾə] |
outta |
Exceptions
- Stressed/emphasized: "I said OF, not OFF" — V is pronounced when stressed
- Careful speech: In formal contexts, the V may be retained
Informal spellings
These reductions are often written informally:
- kinda = kind of
- sorta = sort of
- lotta = lot of
- outta = out of

H-Dropping ↑
When H disappears in pronouns
What is it?
In connected speech, the /h/ sound is often dropped from unstressed pronouns and auxiliaries: him, her, his, he, has, have, had.
tell him
→
/tɛl hɪm/
→
[tɛl ɪm]
This is why "tell him" sounds like "tell im" and "give her" sounds like "give er".
When does it happen?
H-dropping occurs when:
- Word is unstressed — not emphasized in the sentence
- Not sentence-initial — "He said..." keeps the /h/
**Note:** This only applies to function words (him, her, his, he, has, have, had). Content words like "house" or "happy" always keep their /h/.
Examples
Pronouns: him, her, his, he
| Phrase |
Phonemic |
Phonetic |
| tell him |
/tɛl hɪm/ |
[tɛl ɪm] |
| give her |
/ɡɪv hɜr/ |
[ɡɪv ɚ] |
| did he |
/dɪd hi/ |
[dɪd i] |
| in his |
/ɪn hɪz/ |
[ɪn ɪz] |
Auxiliaries: have, has, had
| Phrase |
Phonemic |
Phonetic |
| I have |
/aɪ hæv/ |
[aɪ əv] |
| could have |
/kʊd hæv/ |
[kʊd əv] |
Exceptions
- Sentence-initial: "He said..." — H is pronounced at the start of a sentence
- Emphatic: "Tell HIM, not her!" — H is pronounced when stressed for emphasis
- Careful speech: In formal contexts, speakers may retain the /h/
Related rules
TH-Dropping in "them" ↑
When "them" becomes "'em"
What is it?
In casual speech, "them" loses its /ð/ sound and becomes "'em" [əm]. This is extremely common in everyday conversation.
tell them
→
/tɛl ðɛm/
→
[tɛl əm]
This is why "tell them" sounds like "tell 'em" and "give them" sounds like "give 'em".
When does it happen?
TH-dropping in "them" occurs when:
- Word is unstressed — part of the natural flow of speech
- In casual/fast speech — very common in everyday conversation
**Note:** Often written as **'em** in informal writing: "Tell 'em I said hi!"
Examples
| Phrase |
Phonemic |
Phonetic |
| tell them |
/tɛl ðɛm/ |
[tɛl əm] |
| give them |
/ɡɪv ðɛm/ |
[ɡɪv əm] |
| ask them |
/æsk ðɛm/ |
[æsk əm] |
| get them |
/ɡɛt ðɛm/ |
[ɡɛɾ əm] |
| let them |
/lɛt ðɛm/ |
[lɛɾ əm] |
**Notice:** In "get them" and "let them", you also get [flapping](/rules/flapping/)! Once the TH is deleted, the T is now before a vowel, so it becomes a flap [ɾ].
Exceptions
- Emphatic: "Tell THEM, not us!" — TH is pronounced when stressed
- Careful speech: In formal contexts, speakers may retain the /ð/
Related rules
- H-Dropping — similar pattern with him/her/his → 'im/'er/'is
- Flap T/D — applies after TH is deleted in "get them", "let them"
Final T/D Elision ↑
When T or D drops in consonant clusters
What is it?
When T or D is part of a consonant cluster (like -st, -nd, -ld) at the end of a word, it often drops completely before a word starting with a consonant.
just say
→
/dʒʌst seɪ/
→
[dʒʌs seɪ]
old man
→
/oʊld mæn/
→
[oʊl mæn]
When does it happen?
T/D elision occurs when:
- T/D is in a cluster — st, nd, ld, ft, kt, etc.
- Next word starts with consonant — not a vowel
- In casual/connected speech — very common in everyday conversation
**Note:** This is different from glottal T. Here the sound is deleted entirely, not replaced.
Examples
| Phrase |
Standard |
Spoken |
| just say |
dʒʌst seɪ |
dʒʌs seɪ |
| old man |
oʊld mæn |
oʊl mæn |
| and then |
ænd ðɛn |
æn ðɛn |
Exceptions
- Before vowels: "just a" keeps the T (or it becomes a flap)
- Careful speech: In formal contexts, the T/D may be pronounced
- Emphasis: "I JUST said that!" — T pronounced for emphasis
Related rules
- Glottal T — single T becomes glottal stop (not deleted)
- Flap T/D — T/D between vowels becomes a flap
NT Cluster Reduction ↑
When T disappears after N
What is it?
In fast, connected American English speech, when T appears after N and before an unstressed vowel, the T is often dropped entirely. You just hear the N sound.
twenty
→
/twɛnti/
→
[twɛni]
This makes "twenty" sound like "twenny" and "internet" sound like "innernet".
When does it happen?
NT reduction occurs in casual, fast speech when:
- T comes after N
- T is followed by an unstressed vowel
**Note:** Words like "contain" [kənteɪn] keep the T because the following vowel is **stressed**.
Examples
Numbers
twenty · seventy · ninety
Common words
internet · interview · international · intermediate · center · enter · printer · santa
-nt- in the middle
plenty · county · mountain · fountain
Exceptions
- Before stressed vowels: contain, entail, intent — T is pronounced
- Formal/careful speech: In formal contexts, the T is usually pronounced clearly
Related rules
Schwa Deletion ↑
When unstressed vowels disappear
What is it?
In natural speech, unstressed schwa vowels [ə] are often dropped entirely, reducing the number of syllables in a word.
comfortable
→
/kʌmfərtəbəl/
→
[kʌmftərbl̩]
"Comfortable" (4 syllables) becomes "comf-ter-bl" (3 syllables) in casual speech.
When does it happen?
Schwa deletion is common when:
- The schwa is in an unstressed syllable
- The surrounding consonants can be pronounced together
- Speaking at normal or fast speed
**Key:** This makes English words shorter than their spelling suggests. "chocolate" is 2 syllables [ˈtʃɔklət], not 3.
Examples

Sounds That Merge or Appear
Dealing with boundaries between words — sounds merge together or new linking sounds appear.
Consonant Gemination ↑
When identical consonants meet at word boundaries
What is it?
When a word ends with the same consonant that the next word begins with, speakers don't pronounce the sound twice. Instead, the consonants merge — but how they merge depends on the type of consonant.
some money
→
/sʌm mʌni/
→
[sʌ mʌni]
This is why "some money" sounds like "suh money" — the two /m/ sounds become one longer /m/.
Three types of consonants
1. Continuous consonants — Lengthening
Fricatives (/f, v, θ, ð, s, z, ʃ, ʒ/), nasals (/m, n, ŋ/), and liquids (/l, r/) can be held continuously. When they meet, the sound is lengthened — pronounced once, but for a longer time.

/foʊn nʌmbɚ/ |
[foʊːnʌmbɚ] |
| more rice |
/mɔr raɪs/ |
[mɔːraɪs] |
2. Stops — Hold and release
Stops (/p, b, t, d, k, g/) cannot be held continuously because they completely block airflow. When they meet, the first stop is held, then released into the second. This creates a brief pause.
| Phrase |
How to say it |
| bad day |
Hold /d/, release into /d/ |
| black cat |
Hold /k/, release into /k/ |
| big game |
Hold /g/, release into /g/ |
3. Affricates — Pronounced twice
Affricates (/ʧ, ʤ/) are pronounced twice without merging.

Glide Insertion ↑
When [w] or [j] links words together
What is it?
When a word ending in a vowel is followed by a word starting with a vowel, English speakers naturally insert a glide sound to link them:
- After rounded vowels (/uː/, /oʊ/, /aʊ/) → insert [w]
- After front vowels (/iː/, /eɪ/, /aɪ/) → insert [j]
go out
→
/ɡoʊ aʊt/
→
[ɡoʊw‿aʊt]
see it
→
/siː ɪt/
→
[siːj‿ɪt]
When does it happen?
Glide insertion occurs when:
- Word ends in a vowel — especially /iː/, /eɪ/, /aɪ/, /oʊ/, /uː/, /aʊ/
- Next word starts with a vowel
- In connected speech — words flow together naturally
**Note:** This is automatic and unconscious for native speakers — they don't think about inserting these sounds.
Examples
[w] after rounded vowels
| Phrase |
Standard |
Spoken |
| go out |
ɡoʊ aʊt |
ɡoʊw‿aʊt |
| do it |

Exceptions
- Slow/careful speech: Speakers may pause between words instead of linking
- After schwa: No glide is typically inserted after /ə/

Syllable Structure
How English handles unstressed syllables — consonants forming their own syllables.
Syllabic N ↑
When N forms its own syllable
What is it?
In casual American English, when -en or -on follows certain consonants, the schwa vowel is dropped and N becomes syllabic [n̩] — it forms its own syllable without a vowel before it.
garden
→
/ɡɑrdən/
→
[ɡɑrdn̩]
The small line under the N [n̩] indicates it's syllabic.
When does it happen?
Syllabic N commonly occurs after:
- D — sudden, garden, hidden
- T — button, kitten (with glottal stop)
- Z/S — reason, prison, listen
**Key:** The preceding consonant and the N blend together without a distinct vowel sound between them.
Examples
After D
garden · sudden · hidden · wooden · burden
After S/Z
reason · season · prison · listen · lesson
After T (with glottal stop)
button · kitten · cotton · written
See Glottal Stop + Syllabic N for more on the T + syllabic N pattern.
Related rules
Syllabic L ↑
When L forms its own syllable
What is it?
In words ending with -le or -al, the schwa vowel is often dropped and L becomes syllabic [l̩] — it forms its own syllable without a vowel before it.
bottle
→
/bɑtəl/
→
[bɑɾl̩]
The small line under the L [l̩] indicates it's syllabic. Note that the T also becomes a flap in this word.
When does it happen?
Syllabic L occurs in words ending with:
- -tle — bottle, little, battle
- -dle — middle, puddle, handle
- -ble — table, able, bubble
- -ple — apple, simple, people
- -al — final, normal, mental
Examples

bottle · little · battle · settle · kettle · cattle
-dle words
middle · puddle · handle · candle · needle
-ble/-ple words
table · able · apple · simple · people · trouble
