Within the framework of an acoustic-visual (AV) speech synthesizer, we describe a preliminary tongue model that is both simple and flexible, and which is controlled by 3D electromagnetic articulography (EMA) data through an animation interface, providing realistic tongue movements for improved visual intelligibility. Data from a pilot study is discussed and deemed encouraging, and the integrati...
The Synthesizer Generator and Pan are two popular environment generators. While having the same basic goal of assisting in the development of interactive environments, they use rather different mechanisms to reach this goal. This paper discusses the three basic descriptive components used in environment generation: syntactic, semantic, and user interface descriptions. The contrasting approaches...
one of the interesting topics on multimedia domain is concerned with empowering computer in order to speech production. speech synthesis is granting human abilities to the computer for speech production. data-based approach and process-based approach are the two main approaches on speech synthesis. each approach has its varied challenges. unit-selection speech synthesis and statistical parametr...
The aim of this research was to develop a flexible, high quality articulatory speech synthesis tool. One feature of this research tool is the simulated annealing optimization procedure that is used to optimize the vocal tract parameters to match a specified set of formant characteristics. Another aspect of this study is the derivation of a new form of the acoustic equations. A transmission-line...
An architecture for highly-interactive human-like spoken-dialog agent is discussed in this paper. In order to easily integrate the modules of different characteristics including speech recognizer, speech synthesizer, facial-image synthesizer and dialog controller, each module is modeled as a virtual machine that has a simple common interface and is connected to each other through a broker (comm...
A low-power monolithic clock synthesizer suitable for use in mobile P platforms is presented. Clock synthesis is accomplished using an all-Si RF LC reference oscillator that does not require an external frequency reference. Fabricated in 0.18 m CMOS, the developed clock synthesizer demonstrates 1% frequency accuracy over process, voltage, and 0-70 C, exhibits 7.4/21/33psrms period jitter on 528...
This paper presents a complete statistical speech synthesizer for Myanmar which includes a syllable segmenter, text normalizer, grapheme-to-phoneme convertor, and an HMM-based speech synthesis engine. We believe this is the first such system for the Myanmar language. We performed a thorough human evaluation of the synthesizer relative to human and re-synthesized baselines. Our results show that...
A neural network is used to produce formant data for the Holmes parallel formant speech synthesizer [2] from an allophonic transcription of plain english text. This paper presents results obtained from training a back propagation neural network using speech generated by a conventional speech synthesizer. The network is able to learn to reproduce the basic form of formant transitions between all...
This paper presents the design consideration of high order digital AZ modulators used as modulus controller for fractional-N frequency synthesizer. A third-order MASH structure (MASH 1-2) is designed and implemented which allows for the input to operate over 75% of the input adder capacity. The number of the output levels is reduced to two bits. The circuit was verified through simulation, ASIC...
Unfortunately, most of the articles and books written about designing the Loop Filter for PLL synthesizers dwell in the theoretical and try to cover the subject for all cases of PLL synthesizer design. This article will consider the design of a simple passive three-pole Loop Filter typically used in low voltage, low operating bandwidth synthesizer applications. This approach will simplify and d...
