发音与拼写Pronunciation & Spelling
No common English word rhymes exactly with analog (/ˈæn.ə.lɑːɡ/). Catalog (/ˈkæt.ə.lɑːɡ/) shares the final /əlɑːɡ/ but has /t/ instead of /n/ after the stressed vowel; dialogue (/ˈdaɪ.ə.lɑːɡ/), monologue (/ˈmɑː.nə.lɑːɡ/), and prologue (/ˈproʊ.lɑːɡ/) have different stressed vowels. All are spelling lookalikes.
