Pronouncing -ed endings correctly makes a big difference. When a student can pronounce the -ed endings he will be much easier to understand. Comprehensible English is the goal of accent modification.
There is a common method of teaching -ed endings by using /d/, /t/ and /id/. This was a little confusing for my lower students, so I developed a “shortcut” to pronouncing -ed endings.
Words ending in T or D, add ‘id’ and say it as a separate syllable.
Words ending in all other sounds, add “d” and DON’T say it as a separate syllable.
Important tip! Beginning D is said with a puff of air. Ending D is said with NO PUFF OF AIR! This is helpful, when students say “gooda” for good, “hadda” for had, “playeda” for played or “moveda” for moved. No puff of air here will help your student’s English to be more comprehensible.
