Let's have a look at the pronunciation of the ending of regular verbs

1) [t] final sound

Verbs ending in voiceless sounds [p, k, θ, f, s, ʃ, tʃ] cause the “-ed” ending to be pronounced as the voiceless [t] (with no vocal chord vibration).

•  [p] “He popped a balloon.” [papt]
• [k] “They talked a lot” [takt]
• [θ] “th”: “She frothed a cup of milk” [frawθt]
• [f] “I laughed at the movie.” [læft]
• [s] “She kissed a frog.” [kIst]
• [ʃ] “sh”: “We brushed it off.” [bruʃt]
• [tʃ] “ch”: “I reached around for it.” [riytʃt]

2) [d] final sound

Verbs ending in the voiced sounds [b, g, ð, v, z, ʒ, dʒ, m, n, ŋ, r, l] cause the “-ed” ending to be pronounced as a voiced [d].

•  [b] “It bobbed up and down.” [babd]
• [g] “He begged her to stay.” [bɛgd]
• [ð] “She breathed loudly.” [briyðd]
• [v] “They loved it.” [luvd]
• [z] “We raised her expectations.” [reyzd]
• [dʒ] “They bridged the gap.” [brIdʒd]
• [m] “I claimed it was mine.” [kleymd]
• [n] “They banned new members.” [bænd]
• [ŋ] “She banged into the chair.” [bæŋd]
• [r] “He cleared it up.” [kliyrd]
• [l] “I rolled up the paper.” [rowld]

3)  [ɪd] final sound

Verbs ending in the sounds [t] or [d] will cause the “-ed” ending of a verb to be pronounced as the syllable  [ɪd].

• [t] “She edited the research paper.” [ɛdɪtɪd]
• [d] “We ended the game early.” [ɛndɪd]
• [d] “He breaded the chicken.” [brɛdɪd]
