Punctuation restoration is the process of adding punctuation symbols to raw text. It is typically used as a post-processing task of Automatic Speech Recognition (ASR) systems. In this paper we present an approach for punctuation restoration for texts in Slovene language. The system is trained using bi-directional Recurrent Neural Networks fed by wo...

Serious effects of noise present in room impulse responses (RIRs) on evaluation of room acoustical parameters can be compensated by applying different methods. One of the preferred methods is based on the noise subtraction, RIR truncation and correction for truncation. This paper presents a procedure for calculation of the correction term that shou...

Software development is a complex process that requires disciplined engineering approaches. Empirical studies show that companies still don’t document their development practice, or if they do, these are not up-to-date and do not reflect how they really develop software. The main objective of this paper is to propose an approach that can help compa...

IoT Platform marketplace is gaining a lot of attention in many areas. The paper presents an interoperable and extensible IoT framework that follows oneM2M standard. The framework is validated by a reference implementation that includes automatic sensor recognition and pairing, NoSQL support, complex event processing and alarming and extensions for...

This paper describes a software system for testing students' knowledge using modern web technologies. The goal was to create an application that would help the students to interactively learn the subject Intelligent Systems. As an example, for this learning system the field of formal logic was chosen, but it is possible to implement tests for other...

Noise represents one of the most significant disturbances in measured room impulse responses (RIRs), and it has a potentially large impact on evaluation of the decay parameters. In order to reduce noise effects, various methods have been applied, including truncation of an RIR. In this paper, a procedure for the response truncation based on a model...

Software development process is like any other business process composed of activities carried out by process participants in order to achieve a certain goal. In contrast to a typical business process that is relatively deterministic and thus repeatable, software processes are much more dynamic in nature and dependent on a number of circumstances....

Estimation of speech power spectral density has special importance in speech analysis, synthesis and recognition. It is of practical interest to derive an adequate analytic function that describes speech power spectral density, like the one standardized by CCITT convention. In this paper, the analytical approximation of experimentally obtained spee...

Power spectral density represents one of important characteristics of speech. The estimation of its value is done using various approaches and algorithms. In this paper, the power spectral density of speech in Serbian language is calculated by applying severel methods. For that purpose,. the speech base is formed in a such way that 8 speakers read...
