Measuring pitch extractors' response to frequency-modulated multi-component signals
Hideki Kawahara, Kohei Yatabe, Ken-Ichi Sakakibara +3
This article focuses on the research tool for investigating the fundamental frequencies of voiced sounds. We introduce an objective and informative measurement method of pitch extr…
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…
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…
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…
