| Abstract(in English) | This paper has two aims that are to propose a novel bandwidth extension (BWE) method considering aliasing artifacts, and to apply various BWE methods to speaker verification to evaluate the effectiveness of the BWE ones. There are bandwidth extension methods not only to enhance narrowband signals but also to adapt signals to super-wideband systems. It has been reported that statistical based BWE approaches can estimate clear wideband and super-wideband signals. Recently, a non-linear BWE method has also been reported as a resynthesis approach. In this paper, it is first pointed out that digital signals generated by the non-linear BWE methods include some aliasing artifacts due to the band limitation to be decided according to the sampling frequency. Next, a new non-linear artificial BWE method, which allows us to avoid the influence of aliasing artifacts, is proposed. Moreover, to evaluate the proposed framework, speaker verification experiments and objective tests, i.e. PESQ and RMS-LSD, are conducted. Especially, experimental results show that speech signals extended to 32 kHz by the proposed framework provide the error reduction of 29.7%, compared with conventional methods. |
