As importance of the phase of complex spectrogram has been recognized widely, many
techniques have been proposed for handling it. However, several definitions and …

Voice morphing is a powerful tool for exploratory research and various applications. A
temporally variable multi-aspect morphing is extended to enable morphing of arbitrarily …

A closed-form representation of anti-aliased LF model is derived for a LPF function family
based on cosine series. The Matlab based implementation of the derived form provides …

While log-amplitude mel-spectrogram has widely been used as the feature representation
for processing speech based on deep learning, the effectiveness of another aspect of …

Sounds created by a periodic process have a Fourier representation with harmonic structure–
ie, components at multiples of a fundamental frequency. Harmonic frequency relations are a …

Many researchers have proposed that sensorimotor information about the dynamic
production of speech gestures can supplement the auditory perception of speech. Here we …

Another simple and high-speed F0 extractor with high temporal resolution based on our
previous proposal has been developed by adding a higher-order symmetry measure. This …

The Velvet noise is a sparse signal which sounds smoother than Gaussian white noise. We
propose the direct use of the velvet noise and application of its variant for speech and …

Realistic reconstruction and manipulation of strong vocal expressions found in singing
voices is a challenging and exciting topic. A speech analysis, modification and resynthesis …

A group delay-based excitation source analysis and design method is introduced for
extension of TANDEM-STRAIGHT, a speech analysis, modification and synthesis system …
