1. A computer-implemented training system for speech translation, comprising: a discriminative training component derived from a decision rule of a speech translation component, the speech translation component recognizes speech input using a recognition process and translates a recognition output to multiple hypotheses as translation output using a machine translation process, the discriminative training component includes an objective function that integrates the recognition process and the machine translation process; and a processor that executes computer-executable instructions associated with at least the training component.
