Concatenative synthesis is currently the favoured approach to text-to-speech synthesis, yet it has fundamental limitations. In the longer-term, articulatory synthesis has much greater potential. Different approaches to articulatory synthesis are discussed in terms of the choices made concerning the articulatory processes modelled, the simplifying assumptions, and the data collected.

nanobiotechnology appears to be an emerging science which leads to new developments in the field of medicine. importance of the magnetic nanomaterials in biomedical science cannot be overlooked. the most commonly used chemical methods to synthesize drugable magnetic nanobeads are co-precipitation, thermal decomposition and microemulsion. however monodispersion, selection of an appropriate coati...

We describe the attempt to synthesize emotional speech with a concatenative speech synthesizer using a parameter space covering not only f0, duration and amplitude, but also voice quality parameters, spectral energy distribution, harmonics-to-noise ratio, and articulatory precision. The application of these extended parameter set offers the possibility to combine the high segmental quality of c...

A simple quantitative approach to enable chemists to compare alternative chemical syntheses on the lab bench with respect to their resource usage and their potential environmental impact is proposed; this may be useful for the systematic design of more sustainable processes. We consider as metrics the mass index S(-1) and the environmental factor E to characterize quantitatively the reaction in...

We present a language to specify syntax guided synthesis (SyGuS) problems. Syntax guidance is a prominent theme in contemporary program synthesis approaches, and SyGuS was first described in [1]. This paper describes concretely the input format of a SyGuS solver.

This paper describes our on-going work in the area of text-tospeech synthesis, specifically on concatenative techniques. Our preliminary work consisted in investigating the current trends in concatenative synthesis and the problems that could arise when we apply the existing state-of-the art solutions to the specific case of European Portuguese. Our ultimate goal is to develop a text-to-speech ...

Regions of nonmodal phonation, exhibiting deviations from uniform glottal-pulse periods and amplitudes, occur often and convey information about speakerand linguistic-dependent factors. Such waveforms pose challenges for speech modeling, analysis/synthesis, and processing. In this paper, we investigate the representation of nonmodal pulse trains as a sum of harmonically-related sinewaves with t...
