Pronunciation

American English

• IPA Pronunciation: /ˈrɛɡjəleɪtər/
• Respelling: REG-yuh-lay-tur (with "REG" as in "regular," "yuh" as a quick, soft sound, "lay" as in "play," and "tur" as in "tour")

British English

• IPA Pronunciation: /ˈrɛɡjʊleɪtə/
• Respelling: REG-yuh-lay-tuh (similar to American English, with "REG" as in "regular," "yuh" as a quick, soft sound, "lay" as in "play," and "tuh" as a soft ending like in "sofa")

In both dialects, "regulator" is pronounced with the stress on the first syllable, "REG." The main difference lies in the final syllable, where American English tends to have a more pronounced 'r' sound ("tur"), while British English often ends more softly ("tuh"). The pronunciation in both accents effectively conveys the regulatory role implied by the word.
