Sound Safeguarding for Acoustic Measurement Using Any Sounds: Tools and Applications
Hideki Kawahara, Kohei Yatabe, Ken-Ichi Sakakibara
We demonstrate tools and applications developed based on the method of "sound safeguarding," which enables any sound to be used for acoustic measurements. We developed tools for pr…
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 Multiple Acoustic Attributes Using Structured Periodic Test Signals Including Music and Other Sound Materials
Hideki Kawahara, Kohei Yatabe, Ken-Ichi Sakakibara +2
We introduce a general framework for measuring acoustic properties such as liner time-invariant (LTI) response, signal-dependent time-invariant (SDTI) component, and random and tim…
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…
