This paper presents a reduced order robust gain-scheduling approach for the control of the diesel auxiliary power unit (APU) for series hybrid vehicles. The nonlinear plant dynamics are converted into a linear parameter-varying (LPV) form with parametric uncertainties, in which only partial information of the plant states is available. For this type of LPV system, a new reduced order robust gai...

This chapter introduces Mandarin Text-To-Speech (MTTS) synthesis. Beginning with a brief review on the development history of MTTS and attributes of MTTS, three main constituents of the technology are presented: 1) Text processing: word segmentation, disambiguation of polyphones, and analysis of rhythm structure; 2) prosodic processing: features of Mandarin prosody, and prosody prediction, and;...

The parameter synthesis problem for timed automata is undecidable in general even for very simple reachability properties. In this paper we introduce restrictions on parameter valuations under which the parameter synthesis problem is decidable for LTL properties. The proposed problem could be solved using an explicit enumeration of all possible parameter valuations. However, we introduce a symb...

Ibibio is a Nigerian tone language, spoken in the south-east coastal region of Nigeria. Like most African languages, it is resource-limited. This presents a major challenge to conventional approaches to speech synthesis, which typically require the training of numerous predictive models of linguistic features such as the phoneme sequence (i.e., a pronunciation dictionary plus a letterto-sound m...

Statistical parametric speech synthesis, based on hidden Markov modellike models, has become competitive with established concatenative techniques over the last few years. This paper offers a non-mathematical introduction to this method of speech synthesis. It is intended to be complementary to the wide range of excellent technical publications already available. Rather than offer a comprehensi...

The goal of this paper is to evaluate several extensions of Wei and Levoy’s algorithm [1] for the synthesis of laminar volumetric textures constrained only by a single 2D sample. Hence, we shall also review in a unified form the improved algorithm proposed by Kopf et al.[2] and the particular histogram matching approach of Chen and Wang [3]. Developing a genuine quantitative study we are able t...

Accurate modeling of co-articulation, the contextsensitive merging of the boundaries between allophones in continuous speech, is vital for natural sounding speech synthesis. This paper describes initial research investigating the use of Bézier Curves to form models of co-articulation in human speech. A 12th order, pitch synchronous line spectral pair (LSP) [1] analysis is performed on a corpus ...

Cantor Digitalis is a performative singing synthesizer that is composed of two main parts: a chironomic control interface and a parametric voice synthesizer. The control interface is based on a pen/touch graphic tablet equipped with a template representing vocalic and melodic spaces. Hand and pen positions, pen pressure, and a graphical user interface are assigned to specific vocal controls. Th...

The great advantage of using a glottal source model in parametric speech synthesis is the degree of parametric flexibility it gives to transform and model aspects of voice quality and speaker identity. However, few studies have addressed how the glottal source affects the quality of synthetic speech. Here, we have developed the Glottal Spectral Separation (GSS) method which consists of separati...
