Spelled entirely by ear, and it is a good transcription: k for the hard sound, and no i in the fourth syllable because there is nothing there to hear. What it cannot show is that the word is a compound. Lyco and podium are two pieces, each with its own history, and the letters that mark the join are the ones speech has worn away.
