I am using Speech to Text REST API in my work.

Taking help of the documentation https://learn.microsoft.com/en-us/azure/cognitive-services/speech-service/rest-speech-to-text-short#pronunciation-assessment-parameters

The response does not match with the documentation. I am getting a new variable with value 0 e.g.

 "Words": [
          {
            "Word": "how",
            "Offset": 600000,
            "Duration": 2400000,
            "ErrorType": "None",
            "Confidence": 0,
            "AccuracyScore": 62
          },
          {
            "Word": "is",
            "Offset": 3100000,
            "Duration": 900000,
            "ErrorType": "None",
            "Confidence": 0,
            "AccuracyScore": 92
          },
          {
            "Word": "the",
            "Offset": 4100000,
            "Duration": 1100000,
            "ErrorType": "None",
            "Confidence": 0,
            "AccuracyScore": 100
          }
]

Can you please help as what is the purpose of the variable "Confidence" and why is it value always 0?

Thanks
