So since Korean is considered Altaic too, I guess Korean should have Turkic/Altaic style romanization too, although 어, which is pronounced /ʌ/, is not found in any of the Turkic/Altaic languages I know; hence, it is difficult to find a letter for it (I will just keep 'eo' for now).

Example:

어떤 사람들은 한국어가 알타이 언어라고 생각합니다

Altaic transliteration:

"Eotteon saramdıleun hangugeoga altai eoneorago sänggaghabnida"

NOTE: I am using "ä" instead of "ae" for the last word because the vowel "애" is pronounced /ɛ/, which is kind of close to the sound of "ə" in Azeri and Kazakh, as well as ä in Turkmen.
