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…
An objective test tool for pitch extractors' response attributes
Hideki Kawahara, Kohei Yatabe, Ken-Ichi Sakakibara +3
We propose an objective measurement method for pitch extractors' responses to frequency-modulated signals. It enables us to evaluate different pitch extractors with unified criteri…
Objective measurement of pitch extractors' responses to frequency modulated sounds and two reference pitch extraction methods for analyzing voice pitch responses to auditory stimulation
Hideki Kawahara, Kohei Yatabe, Ken-Ichi Sakakibara +3
We propose an objective measurement method for pitch extractors' responses to frequency-modulated signals. The method simultaneously measures the linear and the non-linear time-inv…
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…
A modulation property of time-frequency derivatives of filtered phase and its application to aperiodicity and fo estimation
Hideki Kawahara, Ken-Ichi Sakakibara, Masanori Morise +2
We introduce a simple and linear SNR (strictly speaking, periodic to random power ratio) estimator (0dB to 80dB without additional calibration/linearization) for providing reliable…
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…
