“…The input signal from the microphone was analyzed by a frequency alteration device (FAD) as described by Katseff et al (2012), based on the method of sinusoidal synthesis (Quatieri and McAulay, 1986). The input signal was recorded with a 32-bit sampling depth at a rate of 11 025 Hz, generating a frame size of 3 ms.…”

A given speech sound will be realized differently depending on the context in which it is produced. Listeners have been found to compensate perceptually for these coarticulatory effects, yet it is unclear to what extent this effect depends on actual production experience. In this study, whether changes in motor-to-sound mappings induced by adaptation to altered auditory feedback can affect perceptual compensation for coarticulation is investigated. Specifically, whether altering how the vowel [i] is produced can affect the categorization of a stimulus continuum between an alveolar and a palatal fricative whose interpretation is dependent on vocalic context is tested. It was found that participants could be sorted into three groups based on whether they tended to oppose the direction of the shifted auditory feedback, to follow it, or a mixture of the two, and that these articulatory responses, not the shifted feedback the participants heard, correlated with changes in perception. These results indicate that sensorimotor adaptation to altered feedback can affect the perception of unaltered yet coarticulatorily-dependent speech sounds, suggesting a modulatory role of sensorimotor experience on speech perception.

“…For speech and audio processing, sinusoidal models have been applied in areas such as speech coding (e.g., [1]- [3]) and enhancement (e.g., [4], [5]), speech signal transformations (e.g., [6]- [8]), music synthesis (e.g., [9], [10]), and more recently low bit-rate audio coding (e.g., [11]- [13]). …”

Abstract-The problem of modeling a signal segment as a sum of exponentially damped sinusoidal components arises in many different application areas, including speech and audio processing. Often, model parameters are estimated using subspace based techniques which arrange the input signal in a structured matrix and exploit the so-called shift-invariance property related to certain vector spaces of the input matrix. A problem with this class of estimation algorithms, when used for speech and audio processing, is that the perceptual importance of the sinusoidal components is not taken into account. In this work we propose a solution to this problem. In particular, we show how to combine well-known subspace based estimation techniques with a recently developed perceptual distortion measure, in order to obtain an algorithm for extracting perceptually relevant model components. In analysis-synthesis experiments with wideband audio signals, objective and subjective evaluations show that the proposed algorithm improves perceived signal quality considerable over traditional subspace based analysis methods.Index Terms-Complex exponentials, perceptually relevant sinusoids, psycho-acoustical distortion measure, sinusoidal modeling, speech and audio processing, subspace-based signal analysis.

“…A synthetic speech waveform is said to be shapeinvariant if, after time-scaling, its individual pitch cycles resemble those of the original speech. Attempts to modify the pitch or time-scale of speech without preserving the shape, have been found to produce speech which has a reverberant quality [2]. The temporal structure of a speech waveform is largely influenced by the periodic closure of the glottis.…”

To preserve shape-invariance when pitch or time-scale modifying sinusoidally modelled voiced speech, the phases of the sinusoids used to model the glottal excitation are made to add coherently at estimated excitation points. Previous methods achieve this by estimating excitation phases at synthesis frame boundaries, disregarding the frequency modulation that may occur between the frame boundary and the nearest modified excitation point. This approximation can produce a significant mis-alignment of the excitation phases, leading to distortion of the temporal structure of the synthetic speech. In this paper, a shape-invariant technique is proposed which aligns the excitation phases at excitation points, whilst allowing for variations in the frequency of the sinusoidal components.
