Microsecond-precision sound localization emerges from slow equilibrium dynamics
Toshio Irino
Precise sound localization relies on microsecond sensitivity to interaural time differences (ITDs), yet binaural perception exhibits sluggish tracking of dynamic acoustic cues. How…
Auditory Representation Effective for Estimating Vocal Tract Information
Toshio Irino, Shintaro Doan
We can estimate the size of the speakers based on their speech sounds alone. We had proposed an auditory computational theory of the Stabilised Wavelet-Mellin Transform (SWMT), whi…
WHIS: Hearing impairment simulator based on the gammachirp auditory filterbank
Toshio Irino
A new version of a hearing impairment simulator (WHIS) was implemented based on a revised version of the gammachirp filterbank (GCFB), which incorporates fast frame-based processin…
Speech intelligibility of simulated hearing loss sounds and its prediction using the Gammachirp Envelope Similarity Index (GESI)
Toshio Irino, Honoka Tamaru, Ayako Yamamoto
In the present study, speech intelligibility (SI) experiments were performed using simulated hearing loss (HL) sounds in laboratory and remote environments to clarify the effects o…
Effective data screening technique for crowdsourced speech intelligibility experiments: Evaluation with IRM-based speech enhancement
Ayako Yamamoto, Toshio Irino, Shoko Araki +4
It is essential to perform speech intelligibility (SI) experiments with human listeners in order to evaluate objective intelligibility measures for developing effective speech enha…
Comparison of remote experiments using crowdsourcing and laboratory experiments on speech intelligibility
Ayako Yamamoto, Toshio Irino, Kenichi Arai +4
Many subjective experiments have been performed to develop objective speech intelligibility measures, but the novel coronavirus outbreak has made it very difficult to conduct exper…
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…
A new cosine series antialiasing function and its application to aliasing-free glottal source models for speech and singing synthesis
Hideki Kawahara, Ken-Ichi Sakakibara, Hideki Banno +3
We formulated and implemented a procedure to generate aliasing-free excitation source signals. It uses a new antialiasing filter in the continuous time domain followed by an IIR di…
