PRONUNCIATION LESSON: VOICED × VOICELESS SOUNDS + -ED ENDINGS

1. Voiced vs. Voiceless: the foundation

English consonants fall into two categories:

Voiced sounds

Your vocal cords vibrate.
Put your fingers on your throat → you feel a buzz.

Voiceless sounds

No vibration.
Air flows without vocal-cord voicing.

Important note

All vowels are voiced.
This is why vowels can “carry” the sound in a syllable.

2. Lists of English voiced and voiceless consonants

VOICED CONSONANTS

b, d, g
v
z, zh (as in measure)
j (as in job)
th (as in this)
m, n, ŋ (ng)
l, r
w, y
All vowels: a, e, i, o, u → always voiced

VOICELESS CONSONANTS

p, t, k
f, s, sh
ch
th (as in think)
h

These categories determine the pronunciation of -ed in regular past verbs.

3. How -ED is pronounced

General rule: voiced sounds are followed by a voiced sound /d/, and voiceless sounds by a voiceless sound /t/. Exception:  final /t/ and /d/sounds take an extra /i/ sound.

There are three pronunciations for the ending -ed.

A) -ED = /t/

After voiceless sounds (except /t/).
Examples:
helped → /helpt/
worked → /wɜːrkt/
kissed → /kɪst/
washed → /wɒʃt/

B) -ED = /d/

After voiced sounds (including all vowels), except /d/.
Examples:
played → /pleɪd/
lived → /lɪvd/
cleaned → /kliːnd/
opened → /ˈoʊpənd/

 

A short diversion:

MINI PRONUNCIATION LESSON: SHORT /ɪ/ vs. LONG /iː/
Essential, direct, minimal-pair based.

---

1. Core difference

/ɪ/ = short, relaxed, mouth slightly open
/iː/ = long, tense, lips spread more, tongue higher

 Portuguese speakers often make /ɪ/ too close to /iː/; this lesson fixes that.

 

 Pronunciation drill

Focus on:

short /ɪ/ = quick, relaxed

long /iː/ = longer, tense, higher tongue 

sit — seat — sit — seat

live — leave — live — leave

slip — sleep — slip — sleep

fill — feel — fill — feel

 Pratice

1.  sit /sɪt/ — seat /siːt/
2. live /lɪv/ — leave /liːv/
3. slip /slɪp/ — sleep /sliːp/
4. fill /fɪl/ — feel /fiːl/
5. bit /bɪt/ — beat /biːt/
6. ship /ʃɪp/ — sheep /ʃiːp/
7. chip /tʃɪp/ — cheap /tʃiːp/
8. bitch /bɪtʃ/ — beach /biːtʃ/
9. hit /hɪt/ — heat /hiːt/
10. lick /lɪk/ — leak /liːk/
11. pick /pɪk/ — peak /piːk/
12. mill /mɪl/ — meal /miːl/ 

 

 Back to the -ed road

 

C) -ED = /ɪd/ or /əd/

After t or d. Creates an extra syllable.

Examples:
wanted → /ˈwɒntɪd/
needed → /ˈniːdɪd/
decided → /dɪˈsaɪdɪd/
