Find the sounds in 서른
The reference transcription for 서른 is [sʰʌ̹ɾɯn]. Read adjacent consonants together without inserting extra vowels. Korean pronunciation changes when sounds meet. Follow the spoken transcription and connected example rather than reading each Hangul letter in isolation.
1.Aspirated consonants
In 서른: Let a clear puff of air follow the consonant marked /ʰ/. Keep the next vowel connected to it.
Watch out: Do not confuse the breathy release with the tight, low-airflow tense consonants.
2.The eo vowel /ʌ/
In 서른: Use a single open back-to-central vowel. The spelling “eo” in romanization represents one vowel.
Watch out: Do not read eo as an e followed by o.
3.The eu vowel
In 서른: Keep the tongue high and toward the back or center, with the lips unrounded. Listen for a vowel distinct from rounded /u/.
Watch out: English “oo” rounds the lips; that changes this vowel.
