Mobile-assisted language learning applications (MALL) has significant potential in the developing world where access to teachers and classrooms are real barriers to learning. This demonstration of an Android-based mobile language learning application is used to teach vocabulary and employs off-line Automatic Speech Recognition (ASR) and Text-to-speech (TTS) technologies with custom-built langua...

The scheduling problem — one of the central tasks in high-level synthesis — is the problem of determining the order in which the operations in the behavioral description will execute. This tutorial introduces the scheduling problem, and describes four scheduling algorithms commonly used today to solve those problems.

Prophon is an interactive environment for developing applications and conducting research in text-to-speech conversion. The environment, which is written in the programming language Prolog, can be considered as a shell for developing knowledge based systems. It is created specifically for the linguistic domain and encourages an incremental development of text-to-speech systems. Prophon offers a...

This paper presents a preliminary study whose main aim is to characterize four distinct speaking styles according to a limited set of prosodic features, including the length of prosodic phrases (AP and IP), the distribution of stressed syllables, pitch register span, the duration of silent pauses, etc. The analysis was performed using semi-automatic procedures on a corpus consisting of 30 minut...

This study is concerned with the introduction of synthesized speech into the humancomputer interface. A simulated hotel booking system is described which asks for information via either the screen or a DECtalk speech synthesizer. The degree of redundancy within the computer's response set is varied. The perceived 'friendliness' of the system increased with the use of synthesized speech incorpor...

Nowadays green synthesis of metal nanoparticles is a developing area of research. In this study, titanium dioxide nanoparticles were biosynthesized using an aqueous solution of Echinacea purpurea herba extract as a bioreductant. This is novel and interesting method for synthesis of TiO2 nanoparticles. The prepared titanium dioxide nanoparticles were characterized using ultraviolet–visible spect...

In this paper we argue that the trend towards system design requires to teach high-level design, in both lectures and design projects. High-level synthesis and hardware-software codesign are two key words. The main part of our paper presents our experiences with a design project where we used the MIMOLA software system for high-level synthesis of a oating-point pocket calculator chip. We descri...
