如此返回结果如何转换成json?用于nodered流程操作【求教】

最近打算把小爱拦截的nodered搞一下，发现使用了新固件版本后，拦截词返回的信息如下：

asr="{"header":{"dialog_id":"aaac56151d5f587eff067970877d18f5","id":"be9a6833b5af4672b1a90bdf9819f9a2","name":"RecognizeResult","namespace":"SpeechRecognizer"},"payload":{"is_final":false,"results":[{"confidence":0.0,"text":""}]}} 
{"header":{"dialog_id":"aaac56151d5f587eff067970877d18f5","id":"6dc0eeb20bf341dd94c80237b107abbc","name":"RecognizeResult","namespace":"SpeechRecognizer"},"payload":{"is_final":false,"results":[{"confidence":0.0,"text":"室内"}]}}
{"header":{"dialog_id":"aaac56151d5f587eff067970877d18f5","id":"f9134a82028d414a8263862117eed8ad","name":"RecognizeResult","namespace":"SpeechRecognizer"},"payload":{"is_final":false,"results":[{"confidence":0.0,"text":"室内空气"}]}}
{"header":{"dialog_id":"aaac56151d5f587eff067970877d18f5","id":"e59292cd51804d1b95a3ab05b9eceb75","name":"RecognizeResult","namespace":"SpeechRecognizer"},"payload":{"is_final":true,"results":[{"confidence":0.0,"text":"室内空气"}]}}"

如此整体并非标准的json格式，但是每个{"header":{},"payload":{}}单元却是一个完整的json结构，如此格式的返回信息如何整体转换成json给nodered处理？

queries = JSON.parse(msg.payload.asr)

集合这部分该如何写？求教
