Auditory Representation of Speech Signals Using a Matching Pursuit Algorithm and Sparse Coding
Dung Kim Tran, Masashi Unoki (JAIST) EMM2021-87
Abstract (in Japanese) (See Japanese page) 
(in English) Speech signals are the natural carrier of information such as linguistic, speaker individuality, and emotions, etc. Therefore, utilizing perceptual features of speech signals would be beneficial to speech analysis applications. Current solutions combine the Bark scale and a gammatone basis with a matching pursuit algorithm to obtain perceptual features. This paper proposes to use more physiological accurate techniques such as equivalent rectangular bandwidth, a gammachirp basis, and auditory masking effects of gammachirp kernels. Experimental results show that the perceptual features produced by the proposed method can achieve 0.89 PEMO-Q and 3.27 PESQ scores using only 1066 coefficients per second. Furthermore, the proposed method also provides the highest matching accuracy in a pattern matching experiment.
