Is it a t, d or \d?
Many people don’t know whether to pronounce –ed as t, d or \d or Id. Here are some very simple rules:
Rule 1: add a /t/ sound for final voiceless sounds /k/, /p/, /f/, /§/, /t§/, /?/, /s/.
Rule 2: add a /d/ sound for final voiced sounds /g/, /b/, /v/, /d½/,/½/, //, /z/, /l/, /m/, /n/, /r/, /w/.
Rule 3: add an extra –ed /\d/ or /Id/ suffix for final /t/ and /d/ consonants.
-ed: pronounce this ed as a /t/ (Final voiceless sound)
brushed= brushT asked=askT
-ed: pronounce this ed as a /d/ (Final voiced sound)
-ed: pronounce this ed as a /\d/ or /Id/
