2. love, cuddle, kill, lie ==> [d]
Those ended with a voiced sound, read as loved, killd

3. state, wound ==> [Id]
Those ended with a voiced sound, read as statId, woundId

Does that help?

First,i am really glad to get ur reply ^^

hmm...however...i still dont understand how to distinguish if the word is ended with voiced or voiceless..
