BELLO PUNTO, Claudia; RIBAS GONZALEZ, Dayana; SUAREZ FERNANDEZ, Eniel  e  CALVO DE LARA, José R.. Speech quality measures in speaker recognition systems. EAC [online]. 2015, vol.36, n.3, pp. 56-68. ISSN 1815-5928.

In this work, a study about the relationship between speech quality measuresand speaker recognition performance is presented. To accomplish this, the most significant quality measures for speaker recognition systems were analyzed and four of them (KLPC, KCEP, HD, P563) were selected according to the parameters considered to determine the quality and its relevance in the speaker recognition process. The alternatives for linking quality with speaker recognition performance are described and a set of experiments are conducted. Such experiments were performed in male database on several additive noise conditions to assess the relationship among the recognition result, the quality of the samples and noise present therein from the SNR. Interesting conclusions were obtained for 20 different noise scenarios.

Palavras-chave : Speech quality measures; speaker recognition; additive noise; kurtosis.
