Variations might include:

• Emphasis on the first syllable: STAR-let (emphasizing the stress)
• Alternative vowel sounds: Depending on regional accents, the "a" sound could be transcribed differently (e.g., /æ/ as in "cat" resulting in /ˈstɑːrlɛt/ becoming /ˈstærlet/).
• Simplified spelling: Star-let (a simpler, less technical representation)
