Oh, I have a special way of writing the lyrics when it is dictated to me. No matter what the language of the song, even if it is Bengali, I write it in Hindi. I have certain notations and markings to indicate the way it should be pronounced. I feel the Devanagari script is the closest to the phonetics of the language. English alphabets are not very good for that purpose. Moreover, I listen carefully and try to grasp as much as possible when the lyrics are read to me.
