Mixture of orthogonal sequences made from extended time-stretched pulses enables measurement of involuntary voice fundamental frequency response to pitch perturbation
Hideki Kawahara, Toshie Matsui, Kohei Yatabe +4
Auditory feedback plays an essential role in the regulation of the fundamental frequency of voiced sounds. The fundamental frequency also responds to auditory stimulation other tha…
Frequency domain variant of Velvet noise and its application to acoustic measurements
Hideki Kawahara, Ken-Ichi Sakakibara, Mitsunori Mizumachi +3
We propose a new family of test signals for acoustic measurements such as impulse response, nonlinearity, and the effects of background noise. The proposed family complements diffi…
GEDI: Gammachirp Envelope Distortion Index for Predicting Intelligibility of Enhanced Speech
Katsuhiko Yamamoto, Toshio Irino, Shoko Araki +2
In this study, we propose a new concept, the gammachirp envelope distortion index (GEDI), based on the signal-to-distortion ratio in the auditory envelope, SDRenv to predict the in…
Frequency domain variants of velvet noise and their application to speech processing and synthesis: with appendices
Hideki Kawahara, Ken-Ichi Sakakibara, Masanori Morise +3
We propose a new excitation source signal for VOCODERs and an all-pass impulse response for post-processing of synthetic sounds and pre-processing of natural sounds for data-augmen…
