The word "should" is pronounced as /ʃʊd/ in its strong form and /ʃəd/ in its weak form. The pronunciation consists of:

• /ʃ/ as in "she" (the "sh" sound)
• /ʊ/ as in "foot" (a short "oo" sound)
• /d/ as in "day" (the "d" sound)

The "l" in "should" is silent, so it is not pronounced. The word rhymes with "good," "hood," and "wood." In casual speech, the vowel may be reduced to a schwa sound /ə/, and sometimes the "d" at the end is dropped before a consonant, making it sound like "shuh" in fast, connected speech. So, pronounced clearly, "should" sounds like "shood." In faster, more casual speech, it can sound more like "shuh" before certain words.
