A METHOD AND A DEVICE FOR OBJECTIVE SPEECH QUALITY ASSESSMENT WITHOUT REFERENCE SIGNAL |
摘要 |
<p>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 recoder (2) is a speech codec. <IMAGE></p> |
