I'm confused when you American say "stoped" or "listedned", the last word "ed", you pronounce "t" or "d"? I always forget the rule, and do you really pronouce them clearly as "t" or "d"?
If the verb ends with "t" or "d" sound (notice I wrote SOUND), the final "ed" sounds exactly like that:

want - wanted /wanted/
wound - wounded /wunded/

Notice that the "ed" sound is not like in "led". It sounds like in "lid" (short /i/ sound).

If the final sound of the verb is voiceless (no vibration) such as "sh", "tch" or "s"; final t-sound is used:

wash - washed /wosht/ (impossible to write phonemes here, uh?)
watch - watched /wotcht/
pass - passed /past/

If the final sound is voiced (with vibration) such "m", "n", "b", "z"; final d-sound is used:

comb - combed /comd/ (notice silent b)
plan - planned /pland/
sob - sobbed /sobd/
raise - raised /reizd/

It's very good to know, I have the same problem for a long time.
Students: Are you brave enough to let our tutors analyse your pronunciation?
thanks a lot! I understand it totally, thanky for resolving my problems.
hi everyone

what about verb 'to look'? I pronounce it with a /t/ sound at the end. Is this word ending in a unvoiced sound?

Well, the real question should be which sounds are unvoiced sounds?

Thank you in advance

Hi! belinda.

Voiceless sounds include /p/, /f/, /k/, /t/, /s/, and /th/ such as in 'mouth'.

Except for the case of /t/, /t/ sound follows when 'ed' is added to all the voiceless consonants. /t/ and /d/ are pronounce /id/ respectively as explained above.

You may now know how to pronouce 'looked' as a voiceless consonant.
All vowels are voiced while only some consonants are voiced save the ones indicated above. The best way to tell if an individual sound is voiced or voiceless is by making that sound with your fingers touching your adam's apple. If you feel vibration with your fingers, it is voiced, and if not, voiceless.

I hope it helps.

Hi Leah,

There is no absolute rule on which you might rely to make this easy. As with all spoken language, actual pronunciation is a matter of repeating sounds as they are "commonly" made. That is, the two words you list are typically pronounced as you state, though their spellings are the same. But that would also be true for words spelled differently, such as "lord" and "board." The pronunciation is the same, though the spellings differ. And this is especially true of English: we have many such words. This is one of those situations where you just have to remember by rote - no way around it! Good luck!
The ending or suffix ed has three sounds:













That's how we teach children in first grade and up how to say the sound. There's no rhyme or reason as to why the sound changes.

On the contrary, if you've read this whole thread, you should know that the pronunciation of the -ed ending has to do with the phonetic properties of the final sound of the word to which it is attached.
