The manipulation of prosody, including pitch, duration and intensity, is one of the leading approaches in synthesizing emotion. This paper reports work on the development of a Malay Emotional synthesizer capable of expressing four basic emotions, namely happiness, anger, sadness and fear for any form of text input with various intonation patterns using the prosody manipulation principle. The sy...

This paper describes a hidden Markov model (HMM) based visual synthesizer designed to assist persons with impairedhearing. This synthesizer builds on results in the area of audio-visual speech recognition. We describe how a correlation HMM can be used to integrate independent acoustic and visual HMMs for speech-to-visual synthesis. Our results show that an HMM correlating model can signi cantly...

Reversible circuits form the backbone for many promising emerging technologies such as quantum computing, low power/adiabatic design, encoder/decoder devices, and several other applications. In recent years, scalable synthesis of has gained significant attention. this work, we present SyReC Synthesizer, a tool reversible based on hardware description language SyReC. allows to describe functiona...

Any audio recording can be turned into a digital musical instrument by feeding it into an audio sampler. However, it is difficult to edit such a sound in musical terms or even to control it in real time with musical expression. This does not change much if a more sophisticated resynthesis method is applied. Many electronic musicians appreciate the direct and clear access to sound parameters a t...

In this study, we present a portable and generic DNA bioassay system based on in situ oligonucleotide synthesis followed by hybridization based detection. The system include two main parts, an oligonucleotide synthesizer and a fluorescence detection system. The oligonucleotide synthesizer is based on microfluidic technology and capable of synthesizing any desired oligonucleotide which can be ei...

This paper describes a low-voltage, low-jitter clock synthesizer and a temperaturecompensated tunable oscillator. Both of these circuits employ a self-correcting Delay-Locked Loop (DLL) which solves the problem of false locking associated with conventional DLLs. This DLL does not require the delay control voltage to be set on power-up, it can recover from missing reference clock pulses and beca...

After the successful implementation of our speech synthesizer Kempelen in the SMS to voice service of Eurotel, one of the biggest mobile telephone operators in Slovakia, we have found out that several extensions need to be done to make the service even more important for users. In the paper we describe the Slovak speech synthesizer Kempelen, its Hungarian version, we discuss the need of male/fe...

In this paper we describe the development of rules to drive a quasi-articulatory speech synthesizer, HLsyn. HLsyn has 13 parameters, which are mapped to the parameters of a formant synthesizer. Its small number of parameters combined with the computational simplicity of a formant synthesizer make it a good basis for a text-to-speech system. An overview of the rule-driven system, called VHLsyn, ...

The main function of a frequency synthesizer is to deliver a stable and clean signal. However, many applications require not only a fixed frequency signal but also various modulation functions ranging from simple pulse, amplitude, frequency and phase modulation to complex digital modulation formats. Although modulators are usually realized as external devices, they can also be incorporated into...

We present a multi-speaker formant synthesizer based on parameter concatenation. The user can choose among three speakers, two males and one female. The synthesizer stores all the parameters for the basic speaker and linear transformation functions to synthesized the other two. The complete database for one speaker consists of 455 parameterized units (diphones, triphones,...) and the parameters...
