speech to text - DataRecognitionClient returns duplicated results -

-

i using microsoft (oxford) cognitive services speech api client sdk.

the following test result after running sample code stock audio samples , without changing code (as is)

--- ondatashortphraseresponsereceivedhandler --- ********* final n-best results ********* confidence=high, text="what's weather like?" confidence=high, text="what's weather like?"

as can see, getting 2 identical results. wonder if can shed light why (duplicated results)?

this might due fact underlying phoeneme structure might different text recognition. not common can happen.
