With seven sets of audio stream inputs,MicrosoftThe Institute has achieved a typos rate of 22.3%. In the non-overlapping segments of the close-range microphone, the erroneous rate can be controlled within 3%.

The number of users supported by the system depends on the number of microphones in the area. Microsoft pointed out that the technology makes it easy for customers to transcribe session content anytime, anywhere, regardless of whether they have a dedicated microphone array.
