Recently, the tau --> K pi nu\_tau decay spectrum has been measured by the
Belle and BaBar collaborations. In this work, we present an analysis of such
decays introducing a dispersive parametrization for the vector and scalar Kpi
form factors. This allows for precise tests of the Standard Model. For
instance, the determination of f\_+(0)|V\_us| from these decays is discussed. A
comparison and a combination of these results with the analyses of the K\_l3
decays is also considered.
