Este artigo descreve a avaliação objetiva da qualidade sem referência para fala com ruído reduzido. Primeiro, um teste subjetivo é conduzido de acordo com a ITU-T Rec. P.835 para obter a qualidade da fala, a qualidade do ruído e a qualidade geral da fala com ruído reduzido. Com base nos resultados, propomos então um modelo global de estimativa de qualidade. O diferencial do modelo proposto é que a estimativa da qualidade geral é feita apenas utilizando a qualidade de fala e a qualidade do ruído previamente estimadas, ao contrário dos modelos convencionais, que utilizam as características acústicas extraídas. Por fim, propomos um método de avaliação de qualidade objetivo e não referencial utilizando o modelo proposto. Os resultados de um experimento com diferentes algoritmos de redução de ruído e tipos de ruído confirmaram que o método proposto fornece estimativas mais precisas da qualidade geral em comparação com o método descrito em ITU-T Rec. P.563.

Abstract: This paper describes non-reference objective quality evaluation for noise-reduced speech. First, a subjective test is conducted in accordance with ITU-T Rec. P.835 to obtain the speech quality, the noise quality, and the overall quality of noise-reduced speech. Based on the results, we then propose an overall quality estimation model. The unique point of the proposed model is that the estimation of the overall quality is done only using the previously estimated speech quality and noise quality, in contrast to conventional models, which utilize the acoustical features extracted. Finally, we propose a non-reference objective quality evaluation method using the proposed model. The results of an experiment with different noise reduction algorithms and noise types confirmed that the proposed method gives more accurate estimates of the overall quality compared with the method described in ITU-T Rec. P.563.
