Sometimes, an L at the end of the word functions as a syllabic L.  That is to say, it functions as a full syllable (a vowel and a consonant).  It sounds like /əl/ or /ʊl/, with a the vowel being very short and reduced. One strategy for making syllabic L sound natural is to practice using words with ʊl to shape the syllabic L.  For words with ble, try saying bull, then shorten and reduce the vowel to "bl." For example, say "bull, bl, trouble." Listen, repeat, and shadow words and phrases with Syllabic L in this lesson. Video with visuals: https://youtu.be/CCrgIbjr6rs
