Emotions and Voice Quality: Experiments with Sinusoidal Modeling
نویسندگان
چکیده
Voice quality is recognized to play an important role for the rendering of emotions in verbal communication. In this paper we explore the effectiveness of a sinusoidal modeling processing framework for voice transformations finalized to the analysis and synthesis of emotive speech. A set of acoustic cues is selected to compare the voice quality characteristics of the speech signals on a voice corpus in which different emotions are reproduced. The sinusoidal signal processing tool is used to convert a neutral utterance into emotive utterances. Two different procedures are applied and compared: in the first one, only the alignment of phoneme duration and of pitch contour is performed; the second procedure refines the transformations by using a spectral conversion function. This refinement improves the reproduction of the different voice qualities of the target emotive utterances. The acoustic cues extracted from the transformed utterances are compared to the emotive original utterances, and the properties and quality of the transformation method are discussed.

Vibrato in Singing Voice: The Link between Source-Filter and Sinusoidal Models
The application of inverse filtering techniques for high-quality singing voice analysis/synthesis is discussed. In the context of source-filter models, inverse filtering provides a noninvasive method to extract the voice source, and thus to study voice quality. Although this approach is widely used in speech synthesis, this is not the case in singing voice. Several studies have proved that inve...
متن کاملA singing voice synthesis system based on sinusoidal modeling
Although sinusoidal models have been demonstrated to be capable of high-quality musical instrument synthesis [1], speech modi cation [2], and speech synthesis [3], little exploration of the application of these models to the synthesis of singing voice has been undertaken. In this paper, we propose a system framework similar to that employed in concatenation-based text-to-speech synthesizers, an...
متن کاملEffect of voice quality on frequency-warped modeling of vowel spectra
The perceptual accuracy of an all-pole representation of the spectral envelope of voiced sounds may be enhanced by the use of frequency-scale warping prior to LP modeling. For the representation of harmonic amplitudes in the sinusoidal coding of voiced sounds, the effectiveness of frequency warping was shown to depend on the underlying signal spectral shape as determined by phoneme quality. In ...
متن کاملPractical high-quality speech and voice synthesis using fixed frame rate ABS/OLA sinusoidal modeling
This paper describes algorithms developed to apply the Analysis-by-Synthesis/Overlap-Add (ABS/OLA) sinusoidal modeling system to real-time speech and singing voice synthesis. As originally proposed, the ABS/OLA system is limited to unidirectional timescaling, and relies on variable frame length to accomplish time-scale modification. For speech and voice synthesis applications, unidirectional ti...
متن کاملFrequency Warped All-pole Modeling of Vowel Spectra: Dependence on Voice and Vowel Quality
We address the problem of compactly representing the discrete spectral amplitudes of vowel sounds produced by a sinusoidal model. A study of frequency warped all pole model representation of spectral amplitudes has been presented. It has been generally accepted that incorporating Bark scale frequency warping in the all-pole modeling improves the perceived accuracy of the modeled sound. However ...
