Proposal of protocols for speech materials acquisition and presentation assisted by tools based on structured test signals
Hideki Kawahara, Ken-Ichi Sakakibara, Mitsunori Mizumachi +1
We propose protocols for acquiring speech materials, making them reusable for future investigations, and presenting them for subjective experiments. We also provide means to evalua…

Simultaneous measurement of time-invariant linear and nonlinear, and random and extra responses using frequency domain variant of velvet noise
Hideki Kawahara, Ken-Ichi Sakakibara, Mitsunori Mizumachi +2
We introduce a new acoustic measurement method that can measure the linear time-invariant response, the nonlinear time-invariant response, and random and time-varying responses sim…

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…
