Report

Proposal of protocols for speech materials acquisition and presentation assisted by tools based on structured test signals

Autor: Kawahara, Hideki, Sakakibara, Ken-Ichi, Mizumachi, Mitsunori, Yatabe, Kohei

We propose protocols for acquiring speech materials, making them reusable for future investigations, and presenting them for subjective experiments. We also provide means to evaluate existing speech materials' compatibility with target applications.

Simultaneous Measurement of Multiple Acoustic Attributes Using Structured Periodic Test Signals Including Music and Other Sound Materials

Autor: Kawahara, Hideki, Yatabe, Kohei, Sakakibara, Ken-Ichi, Mizumachi, Mitsunori, Kitamura, Tatsuya

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 time-varying (RTV) component simultaneously using structured periodic tes

Simultaneous measurement of time-invariant linear and nonlinear, and random and extra responses using frequency domain variant of velvet noise

Autor: Kawahara, Hideki, Sakakibara, Ken-Ichi, Mizumachi, Mitsunori, Morise, Masanori, Banno, Hideki

Publikováno v: 2020 Asia-Pacific Signal and Information Processing Association Annual Summit and Conference (APSIPA ASC), Auckland, New Zealand, 2020, pp. 174-183

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 simultaneously. The method uses a set of orthogonal sequences made from a

Report

Frequency domain variant of Velvet noise and its application to acoustic measurements

Autor: Kawahara, Hideki, Sakakibara, Ken-Ichi, Mizumachi, Mitsunori, Banno, Hideki, Morise, Masanori, Irino, Toshio

Publikováno v: 2019 Asia-Pacific Signal and Information Processing Association Annual Summit and Conference (APSIPA ASC), Lanzhou, China, 2019, pp. 1523-1532

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 difficulties in existing families, the Swept-Sine (SS), pseudo-random noise
