Käännös - Englanti-Japani - Your voice is fading.

Can I have it in romanji too, please ? With all my thanks.

As in, on the telephone, when you can't hear what the other person is sayng...

Romaji
Anata no koe ga dan-dan kikoe-naku natte-iru
Literally
Your voice is becoming step by step not audible

NOTE:
Leave out the
Anata no
when there's only one possibility, i.e. it's the other's voice you're obviously talking about, not a third party's.
