They go into detail about the rules necessary to know the correction pronunciation of any -ED ending: These rules are for regular verbs in the past tense, for regular past participles and for adjectives that end in ED.
There is a special section about voiced and voiceless (or unvoiced) sounds in English.
You will also find the Woodward -ED Pronunciation chart where you will hear how each each word is said.
