First attempts at incorporating models of frication into an articulatory synthesizer, with a modular and flexible design, are presented. Although the synthesizer allows the user to choose different combinations of source types, noise volume velocity sources have been used to generate turbulence. Preliminary results indicate that the model is capturing essential characteristics of the transfer f...

With a modulo-N accumulator and a set of reference waveforms, a new architecture of high-performance digital frequency synthesizer is devised. The reference waveforms with the same frequency but different phases are passed through a multiplexer to obtain the maximal frequency with an incrementer. A Gray encoder is designed to eliminate the glitch problem. The performance of the synthesizer is i...

In this paper, we show how synthesis can help implement interesting functions involving pattern matching and algebraic data types. One of the novel aspects of this work is the combination of type inference and counterexample-guided inductive synthesis (CEGIS) in order to support very high-level notations for describing the space of possible implementations that the synthesizer should consider. ...

A polyglot speech synthesizer, synthesizes speech for any given monolingual or multilingual text, in a single speaker’s voice. In this regard, a polyglot speech corpus is required. It is difficult to find a speaker proficient in multiple languages. Therefore, in the current work, by exploiting the acoustic similarity of phonemes across Indian languages, a polyglot speech corpus is obtained for ...

A general impedance synthesizer using a minimum number of switching converters is studied in this paper. We begin with showing that any impedance can be synthesized by a circuit consisting of only two simple power converters, one storage element (e.g., capacitor), and one dissipative element (e.g., resistor) or power source. The implementation of such a circuit for synthesizing any desired impe...

In this paper, we show how adaptive modeling within the statistical parametric speech synthesis framework can be applied to Albanian dialects. We develop speaker dependent voices for the Tosk and Gheg dialect and adapt models for the Gheg dialect from the Tosk models. We show that the adapted Gheg models outperform the speaker dependent Gheg model on an intelligibility and dialect classificatio...

This paper presents the study and design of an Integer N synthesizer model for three LoRa ISM bands: 430 MHz 868 915 MHz. The proposed topology is composed by two voltage controlled oscillators working in different bands. presented uses same phase-frequency detector, charge pump loop filter. focused on dynamic steady-state analysis order to infer stability bandwidth. performed shows that settli...

Abstract Wideband hybrid frequency synthesizer with phase-locked loop (PLL) and high-speed direct-to-analog converter (DAC) is presented. The use of special DAC operating modes allows to expand the generating band. Presented also provides a low phase noise due using RF mixer in PLL feedback.
