Investigation on the effects of source directivity on Chinese speech intelligibility based on auralization
Résumé
Subjective Chinese speech intelligibility was evaluated by using an omnidirectional source,i.e., a source with the approximate directivity of human speaker and a human speaker source in both real and simulated rectangular rooms with different reverberation time. The result shows that subjective Chinese speech intelligibility scores have statistical differences under different source conditions . Speech intelligibility scores obtained by using omnidirectional source are lower than those obtained by using the other two sources. Therefore, it will underestimate the speech intelligibility in rooms. Subject Chinese speech intelligibility obtained from auralization is basically the same as that which obtained in actual rooms under different source directivity conditions. By using auralization technique one can properly evaluate the subjective Chinese speech intelligibility even with different directional sources.
