In this paper we report the results obtained from experiments with a database of emotional
speech in English in order to find the most important acoustic features to estimate Emotion …

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 …

The feasibility of representing the excitation source characteristics in expressive voice
signals by an aperiodic sequence of impulses in the time domain is examined in this paper …

A new method for robust estimation of fundamental frequency (F0) from speech signal is
proposed in this paper. The method exploits the high SNR regions of speech in time and …

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 …

In this paper, we study the significance of aperiodicity in the pitch-perception of expressive
voices such as Noh voice and laughter signals. The excitation source characteristics in the …

Aperiodicity in the voice source is caused by changes in the vocal fold vibrations, other than
the normal quasi-periodicity and the turbulence at the glottis. The aperiodicity appears to be …

This paper deals with study of formant and harmonic contours by processing the group delay
(GD) spectrograms of speech signals. The GD spectrum is the negative derivative of the …

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 …

Objective The purpose of this study is to analyze the voice used in kapa haka, a
contemporary indigenous vocal performance from New Zealand, which includes the well …
