Evaluation of UKA Speech-to-Speech System
Within its evaluation activities, ELDA has been contacted to evaluate the simultaneous speech-to-speech translation system of University of Karlsruhe (UKA). To do so, an end-to-end evaluation of UKA automatic simultaneous translation system, built with state-of-the-art components has been carried out recently. End-to-end evaluation shows if, and for which situations, such a system might be advantageous when compared to a human interpreter.
Using talks in English translated into Spanish, we’ve assessed both the recognition and translation components as well as for the overall system. The assessments are carried out by measuring the information preservation and the quality of the speech output. The information preservation is measured by using "comprehesion questionnaires" while the speech output is assessed by asking subjects to rate the quality of the output signal. In addition to subjective tests, automatic metrics such as BLEU or WER are also considered.
Even if the translation process remains the Achilles’ heel of the system, results showed that the system can keep at least half of the information, becoming potentially useful for final users.
