The ending of regular verbs in English can be pronounced in three different ways:

• Voiced alveolar plosive /d/: This sound is made by placing the tongue against the alveolar ridge (the bumpy ridge behind the upper teeth) and voicing the sound. Examples include: played, wanted, helped, needed.
• Voiceless alveolar plosive /t/: This sound is made by placing the tongue against the alveolar ridge and unvoicing the sound. Examples include: walked, talked, kissed, cooked.
• Voiced dental plosive /ɪd/: This sound is made by placing the tongue against the upper teeth and voicing the sound. It is pronounced as a separate syllable, like "id." Examples include: waited, needed, folded, started.

The pronunciation of the ending of a regular verb depends on the final sound of the verb stem. Here are some rules to follow:

• If the verb stem ends in a voiced consonant (b, d, g, j, l, m, n, r, v, w, z), the ending is pronounced as /d/. Notice the word, “close”. The “s” has a “z” sound; thus, the past tense (i.e., “closed”) would fall under this category (i.e., /d/).
• If the verb stem ends in a voiceless consonant (ch, f, k, p, s, sh, t, x), the ending is pronounced as /t/.
• If the verb stem ends in a vowel, the ending is pronounced as /ɪd/.Here is a table summarizing the three pronunciations of the ending of regular verbs:

There are a few exceptions to these rules. For example, the verb "liked" is pronounced as /laɪkt/, even though it ends in a voiced consonant. Also, the verb "ended" is pronounced as /endɪd/, even though it ends in a vowel.

Practicing pronouncing regular verbs out loud is the best way to improve your pronunciation. You can also listen to native English speakers and try to imitate their pronunciation. With practice, you will be able to pronounce the ending of regular verbs correctly.
