Solve Regex problem in Python 2.7 -- 2

I have a regular expression issue to settle: 1) I have a string which I only wish to extract the transcript - "alternatives": [{"confidence": 0.7052744, "transcript": "Toledo come from", {"alternatives": [{"confidence": 0.94460905, "transcript": " hello hello", {"alternatives": [{"confidence": 0.97388196, "transcript": " hello"]} 2) I want to extract all the text of the transcript 3) If there are multiple, extract them out into a full string
