【Abstract】 For employing objective parameters to assess and predict Chinese speech intelligibility, the correlation between Chinese speech intelligibility and useful/detrimental ratio U50 is studied by subjective tests. Their regression equation is also obtained. It shows that the Chinese speech intelligibility is highly correlated with the objective parameter U50 that it could be evaluated by U50 effectively.更多还原
