Statistical Modeling of Sound Aperiodicities
نویسندگان
چکیده
In this work we investigate aperiodicities that occur in the sustained portion of a sound due to phase synchronous versus unsynchronous deviations of the partials. By using an additive sinusoidal model, correlation statistics and phase coupling eeects are considered for various instruments. The phase coupling is shown to be an important characteristic of musical instrument. These analyses are compared to results from Higher Order Statistical analysis and are shown to be equivalent. General applications for sound synthesis are discussed and a simulation of phase uctuations in string instrument is presented.

Prediction of Voice Aperiodicity Based on Spectral Representations in HMM Speech Synthesis
In hidden Markov model-based speech synthesis, speech is typically parameterized using source-filter decomposition. A widely used analysis/synthesis framework, STRAIGHT, decomposes the speech waveform into a framewise spectral envelope and a mixed mode excitation signal. Inclusion of an aperiodicity measure in the model enables synthesis also for signals that are not purely voiced or unvoiced. ...
متن کاملInvestigation of phase coupling phenomena in sustained portion of musical instruments sound.
This work investigates aperiodicities that occur in the sustained portion of a sound of musical instrument played by a human player, due to synchronous versus asynchronous deviations of the partial phases. By using an additive sinusoidal analysis, phases of individual partials are precisely extracted and their correlation statistics and coupling effects are analyzed. It is shown that various mu...

متن کاملAnalytical vibroacoustic modeling of an elastic Rayleigh beam using Green's function
The purpose of this article is to provide an analytical model of the vibroacoustic for an elastic beam submerged in low subsonic flows with mean velocities. In general, vibroacoustic modeling refers to the combined effects of sound propagation and mechanical vibration of the structure. Sound radiations from submerged structures are coupled with physical phenomena because the sound pressures act...
متن کاملOn the Representation of Voice Source Aperiodicities in the MBE Speech Coding Model
We present an investigation of the representation of voice source aperiodicities in the Multi-Band Excitation (MBE) speech model for the compression of narrowband speech. The MBE model is a fixed-frame based analysis-synthesis algorithm which combines harmonic and stochastic components to reconstruct speech from estimated model parameters. Pitch cycle perturbations, such as jitter and shimmer, ...
