AECMOS: A Speech Quality Assessment Metric for Echo Impairment

Marju Purin, Sten Sootla, Mateja Sponza, Ando Saabas, Ross Cutler

ICASSP 2022accepted

Traditionally, the quality of acoustic echo cancellers is evaluated using intrusive speech quality assessment measures such as ERLE [1] and PESQ [2], or by carrying out subjective laboratory tests [3], [4]. Unfortunately, the former are not well correlated with human subjective measures, while the l…

Crowdsourcing Approach for Subjective Evaluation of Echo Impairment

Ross Cutler, Babak Nadari, Markus Loide, Sten Sootla, Ando Saabas

ICASSP 2021accepted

The quality of acoustic echo cancellers (AECs) in real-time communication systems is typically evaluated using objective metrics like ERLE [1] and PESQ [2], and less commonly with lab-based subjective tests like ITU-T Rec. P.831 [3]. We will show that these objective measures are not well correlated…
