通訊產品在噪音環境中語音品質之測試

Speech Quality of Communication Products Under Background Noise Environment

摘要


通訊產品的語音品質提升,已經從原有的客觀性量測,演進至主觀性語音品質的量測。本研究利用聲場重建的技術,產生模擬的背景噪音聲場,可用於待測試通訊產品。利用法規ITU-T P.862中語音品質評等法,評定出通訊產品的MOS分數。本研究對通訊產品在研發過程中的測試環境建立及產品語音品質提昇上,極有助益。

Taipei, Taiwan, June 12, 2010.has been developed from the objective measurement to the subjective voice quality measurement.On this study, sound field reconstruction following ITU-T P.862 has been used to create a background noise test environment for communication products. A subjective score MOS is then calculated by PESQ method of ITU standard. This study, it's useful for improving the speech quality communication products the develpment stage.
