잠깐이라도 네 목소리 듣고 싶어

The line, explained

Late at night, the request gets smaller and smaller. Not 'come back', not even 'see me', just 'let me hear your voice, even for a moment'. That shrinking is what makes the line hurt, and Korean has one particle for it: (이)라도, 'even if it's just'. It says the thing you are asking for is tiny, not ideal, maybe not enough, but you would still take it. Ballads are full of it.

잠깐 means a moment or briefly, the time it takes to say hello. Attach 이라도 and it becomes 잠깐이라도, 'even just for a moment'. The rule is simple: 이라도 after a consonant, 라도 after a vowel. 잠깐 ends in ㄴ, so it takes 이라도, and the ㄴ slides over to make jam-kka-ni-ra-do. With a vowel ending, it is just 라도: 커피라도, at least a coffee; 한 마디라도, even one word.

네 is 'your', a squeezed 너의, and 목소리 is voice. It is a lovely compound: 목 is throat or neck, and 소리 is sound, so a voice is literally 'throat sound'. The ㄱ at the end of 목 makes the next ㅅ sound a little harder, but romanization keeps it as mok-so-ri. 네 목소리 is the object of the wish, and in this line it does not even need the object marker 를, which songs often drop.

듣고 싶어 is 'I want to hear'. 듣다 means to hear or listen, and -고 싶다 is the 'want to' ending you may know from 보고 싶어, I miss you. Put them together and conjugate casually: 듣고 싶어. The ㄷ at the end of 듣 makes the 고 sound tense, almost like kko, though it is written go. The whole line puts the 라도 phrase first, so the smallness of the wish is what you hear before anything else.

Sing it quietly, almost whispering: jam-kka-ni-ra-do, then ne mok-so-ri deut-go si-peo. Then try other small wishes: 한 번이라도, even once; 꿈에서라도, even in a dream; 전화로라도, even over the phone; 멀리서라도, even from far away. Notice that 라도 can sit on top of other particles, like 에서 or 로. In daily life you will hear the friendly version too: 밥이라도 먹자, let's at least grab a meal.
