发明名称 Method and device for objective speech quality assessment without reference signal
摘要 A method of and a device for output based objective speech quality assessment, wherein a degraded output speech signal comprising a speech information portion, is compared ( 5 ) with a reference signal retrieved from the output speech signal. The reference signal is provided by perceptual approximation of the speech information portion of the output speech signal using a speech recoder ( 2 ) producing a reference speech signal of finite bitrate. In a preferred embodiment, the speech recorder ( 2 ) is a speech codec.
