Microsoft® has a vision to make our devices so effortless to use that they all but disappear, and natural language interfaces are a major part of making it happen. But to develop and test the necessary components and algorithms, Microsoft’s world-leading engineers need test equipment that maximizes the signal and minimizes the noise to perform the most valuable, repeatable and purest measurements possible.
