This work exposes some observations on "shaking vowels". These vowels containing a tremolo-like sound are present in amused speech. Some of the temporal and spectral patterns are exposed and observations are given concerning them. This work is a preliminary step towards being able to use these "shaking vowels" along with speech-smiles, speechlaughs and laughter to control the degree of amusemen...

This article reviews research on vocal vibrato and related phenomena. As the vibrato corresponds to a modulation of the fundamental frequency, the primary acoustic attributes are the@equency and amplitude of this modulation as well as its waveform. The range of variation of these parameters in classical operatic singing are discussed as well as the boundaries to similar phenomena such as tremol...

We present a new class of digital audio effects which can automatically relate parameter values to the tempo of a musical input in real-time. Using a beat tracking system as the front end, we demonstrate a tempo-dependent delay effect and a set of beat-synchronous low frequency oscillator (LFO) effects including auto-wah, tremolo and vibrato. The effects show better performance than might be ex...

Within the context of sinusoidal modeling, a new method for the interpolation of sinusoidal components is proposed. It is shown that autoregressive modeling of the amplitude and frequency parameters of these components allows us to interpolate missing audio data realistically, especially in the case of musical modulations such as vibrato or tremolo. The problem of phase discontinuity at the gap...

The detection of deception in human speech is a difficult task but can be performed above chance level by human listeners even when only audio data is provided. Still, it is highly contested, which speech features could be used to help identify lies. In this study, we examined a set of phonetic and paralinguistic cues and their influence on the credibility of speech using an analysis-by-synthes...

We outline a set of audio effects that use rhythmic analysis, in particular the extraction of beat and tempo information, to automatically synchronise temporal parameters to the input signal. We demonstrate that this analysis, known as beat-tracking, can be used to create adaptive parameters that adjust themselves according to changes in the properties of the input signal. We present common aud...

In this work we present a new scenario of analyzing and separating linear mixtures of musical instrument signals. When instruments are playing in unison, traditional source separation methods are not performing well. Although the sources share the same pitch, they often still differ in their modulation frequency caused by vibrato and/or tremolo effects. In this paper we propose source separatio...
