In conventional objective speech quality assessment method, it is required to have the source speech information as well as the processed speech by telephone networks. This paper presents a new paradigm in objective speech quality assessment. In contrast to conventional objective models, the proposed Auditory Non-Intrusive QUality Estimation (ANIQUE) model estimates the quality of speech without using the source speech information at all. ANIQUE is a perceptual model which simulates the functional role of human auditory system at both the peripheral level and central auditory pathway level. The performance of ANIQUE is demonstrated using 19 different subjective MOS databases.
