In this paper, we describe the configuration of our synthesizer, as used for the Blizzard Challenge the first time. Two new UK English voices were built for the DSSP synthesizer, our in-house unit selection synthesizer, which uses non-uniform units and a symbolic description of target prosody. Listening tests indicate reasonable quality although there is still room for improvement.

We describe our research direction to build a 3-D articulatory speech synthesizer. We are employing a usercentred design approach to develop the synthesizer. The end result will be added to the open-source research community. The system infrastructure we are planning is expected to allow for easy integration of current and future research results in vocal tract modelling and vocal sound product...

This paper proposes a new stable design strategy for 1bit high order digital ∆Σ modulator for multistandard fractionalN frequency synthesizer. The proposed digital ∆Σ modulator presents simplicity, low power consumption and controls a dualmodulus divider instead of multi-modulus one as in existing ∆Σ fractional-N frequency synthesizer. Simulation results illustrate the ∆Σ modulator good perform...

This paper presents a new strategy to simulate fractional frequency synthesizer behavioral models with better performance and reduced simulation time. The models are described in Verilog-A with accurate phase noise predictions and they are based on a time jitter to power spectral density transformation of the principal noise sources in a synthesizer. The results of a fractional frequency synthe...

A 2.4GHz frequency synthesizer is proposed as a part of a low cost RF front end for ISM band applications. The frequency synthesizer employed a new dual loop architecture to improve the settling time, while keeping a fine frequency resolution. With a settling time of 30µs, the frequency synthesizer is able to hop at 2k hop/s with less than 10% overhead. When utilized in a digital wireless syste...

This paper gives a description of a modulator for burst-by-burst carrier frequency hopping in time-division multiple-access (TDMA) systems. The architecture consists of a digital frequency synthesizer/modulator for continuousphase modulations (CPM’s) and a fast frequency settling RF synthesizer consisting of one phase-locked loop (PLL). The performance of the digital frequency synthesizer/CPM m...

Carbohydrates play essential roles in nature, such as cell–cell communication, cell growth and immunoresponse. However, the synthesis of structurally well-defined carbohydrates, especially large-sized glycans, is a challenging task. Here we report an automated solution-phase multiplicative complex glycans enabled by preactivation-based, multicomponent, one-pot glycosylation continuous multiplyi...

In this paper, we present an implementation of a modular synthesizer in Haskell using Yampa. A synthesizer, be it a hardware instrument or a pure software implementation, as here, is said to be modular if it provides sound-generating and sound-shaping components that can be interconnected in arbitrary ways. Yampa, a Haskell-embedded implementation of Functional Reactive Programming, supports fl...
