Authors:   Kharkiv National University of Civil Engineering and Architecture, Zinenko K. A.
Published: August 2021

The article is aimed at developing a scientific-methodological approach to a comprehensive assessment of the economic security of a construction enterprise. The author proposes the scientific-methodological approach consisting of the following stages of assessment: 1) assessment of the level of economic security according to the functional components of the construction enterprise, based on the taxonomic approach to the formation of the general integral indicator by V. Plyut method; 2) assessment of the influence of the stakeholders’ interests on the level of economic security of a construction enterprise according to certain groups based on the expert method of score and factor analysis; 3) assessment of the impact of useful (opportunity) and destabilizing (threat) factors on the economic security of a construction enterprise by groups of stakeholders using the factor analysis methods; 4) ranking of stakeholder groups taking into account the priority of influence on the level of economic security of the construction enterprise; 5) determination of the general level of economic security of the construction enterprise, taking into account the interests and factors of influence by groups of stakeholders on the basis of the construction of a comprehensive integrated indicator of economic security of the construction enterprise. Carrying out an assessment of the economic security of a construction enterprise on the basis of the proposed scientific-methodological approach, taking into account the impact of the implementation of stakeholder interests and factors of influence by stakeholder groups, provides an opportunity to obtain a comprehensive assessment of the level of economic security of the enterprise, which contributes to the adoption of more effective managerial decisions to improve the level of economic security, stability of the functioning and development of the construction enterprise.

Authors:   The National Institute for Strategic Studies, Shevchenko O. V.
Published: August 2021

The research is aimed at forming a toolbox for recognizing regional communities according to socio-economic development indicators. A carried out study of scientists’ works demonstrated a lack of evaluation tools for studying groups of regions by levels of disparities, which complicates the study of interregional disparities and the impact of various factors upon them. The paper carries out a classification of levels of disparities in the regions by spheres of development, formes a mathematical apparatus for recognizing and forecasting of levels of disparities in the regions. The groups of regions by levels of disparities in seven spheres of development is researched: general economic, socio-demographic, structural, socio-economic, foreign economic, natural-ecological, production. Three groups of regions were identified by levels of disparities in these areas of development: with balanced sphere disparities, with controlled (restrained) sphere disparities, with uncontrolled (unrestrained) sphere disparities. A spatial-dynamic assessment of disparities in the development of clustered groups of regions is advisable for the development and implementation of regional policy measures aimed at regulating the regional development disparities. The originality of the presented work is the study of cluster groups of regions by the levels of disparities in various spheres of life, which allows to assess interregional disparity in the complex and develop a number of measures to resolve the disparities in the development of regions within the country.

Authors:   Research Centre of Industrial Problems of Development of NAS of Ukraine, Yaroshenko I. V.
Published: August 2021

Each country forms its own systems of territorial organization of power and public administration, which occurs under the influence of the national, historical, geographical, natural, economic, social, cultural, demographic and other features. Considerable attention of researches of scholars and practitioners was paid to the creation and functioning of the territorial community. The choice of theoretical approaches and models of the territorial community influences the efficiency of the functioning of the local self-government system, the ability to fulfill the assigned powers, to ensure a high level of quality of life of citizens and sustainable development of the territory. Studies of global and domestic experience allow to systematize the accumulated knowledge on this issue, which makes it possible to offer a national system of public administration at both the central and the local levels using the best theoretical and practical developments of the countries of the world. Formation of the definition of the concept of the territorial community was carried out over a long historical period under the influence of versatile scientific judgments, ideas, theoretical approaches, practical research. The analysis and study of foreign and domestic experience on this issue is characterized by various formulations, views, principles, signs, etc. regarding the formation and functioning of territorial communities. In parallel with the phrase «territorial community», researchers use other names, such as commune, territorial communion, territorial collectivity, local co-partnership, socio-territorial community, etc. The lack of currently generalized scientific opinion regarding the specification of the content of a certain term, the variety of volumes and approaches to its interpretation confirms the expediency of further research on this topic.

The article is aimed at analyzing the proposals from leading operators in the tourist market of Ukraine, in particular in the city of Kharkiv. The article analyzes the charter offers of travel operators for the summer season 2020. After the analysis, it can be stated that travel operators plan to significantly increase volumes for Turkey (for example, two flights a week to the Turkish Dalaman are planned (in the season 2019, one flight per week was operated)). It is worth noting that travel operators also plan to significantly increase volumes for European areas, in particular Italy. In addition to the proposed flights to the swimming and beach resorts, the summer navigation will also feature direct flights of the airline Ernest, which will allow to develop interesting excursion routes, focusing on the arrival airports in Rome and Milan. At the same time, the expediency of increasing the volume of flights to Calabria can be questioned, because two flights a week is too much for a place that has not yet become a mass resort, which means that it experiences problems with infrastructure development and sufficient availability of accommodation facilities. The article analyzes the proposals of leading operators in the tourist market of Ukraine, according to the findings it can be noted that almost all travel operators - leaders in the number of tourists served consider the Kharkiv region as an attractive market for expanding travel content. The leaders in the number of tourists served were two travel operators who have their own airlines, namely: Sky Up (Join Up) and Azur Air Ukraine (Anex Tour). The undisputed leader in the number of exclusive destinations represented with a guaranteed flight is Join Up, and there is also a tendency to increase volumes with the travel operator TUI. On the basis of a survey, the best travel operators were identified by the ratings of agent-friendly and tourist-friendly, they were: Tez Tour, Join Up, Pegas Touristik, Coral Travel, and TUI.

The article is aimed at forming an express assessment of the level of economic security for a construction enterprise (which, unlike others, is based on an assessment of the level of efficiency of management of contractors and subcontractors) and the choice of a special package of measures to increase the level of economic security. The article analyzes the current state of the civil construction industry in Ukraine, market characteristics of this sector of the economy. There was a decline in the construction sector during 2020–2021, especially in the first half of 2021. Further, there is a slowdown in labor migration, some supply chains of building materials are interrupted; respectively, there is a need to resume economic activity. Also, theoretical studies of the authors allowed to highlight the main aspects of the formation of economic security of enterprise through the analysis of the relevant market and the dynamics of the civil construction industry. The relevance of creating an express assessment of the level of economic security of a construction enterprise is substantiated. An express assessment is proposed to be carried out on the basis of determining the level of efficiency of management of contractors and subcontractors – to what extent they adhere to the traditional policy of value and income formation. The assessment methodology includes four stages: questionnaire (containing 20 questions in four directions of evaluation); processing of questionnaire data (Delphi method is used); formation of an evaluation scale to determine the level of economic security of a construction enterprise; selection of a package of measures to improve the economic security of civil construction enterprises. The packages of measures to improve the economic security of civil construction enterprises are being developed for both the formal and the informal sectors. The authors believe that it is advisable to adapt the proposed package of measures to the characteristics of each individual enterprise using an individual approach. The proposed express assessment will allow monitoring the condition of the construction enterprise in a short time and identify latent crisis phenomena.

Published: August 2021

Assessment of the reliability of banks and their rating is a relevant issue for all participants of the financial market. Taking into account the fact that a methodology should be based on the availability of information data, clarity and openness of the algorithm, and a limited number of analyzed indicators, the authors, for assessing the reliability of the banking system of Ukraine in separate banking groups, chose the most popular methodology of V. Kromonov. The article contains the results of assessment of V. Kromonov's rating model indicators for the period 01.01.2017–01.06.2021 for the banking system of Ukraine in general, as well as for the group of banks with the State-owned share, banks of foreign banking groups and banks with private capital. It is identified that the level of reliability of the banking system of both Ukraine and banking groups is in poor condition, since the calculated values of integral reliability coefficients do not exceed the value of 30 points, which indicates the presence of significant problems in the functioning of the banking market, imbalance of assets and liabilities, low level of solvency of banks and same for liquidity of assets. A comparative characterization showed that the reliability of Ukrainian banks with the State-owned share is significantly inferior to the reliability of banks of foreign banking groups and banks with private capital. It is determined that the amount of equity of the banking system of Ukraine is not sufficient to repay possible losses in case of non-return or return in an impairment form of a working asset. A computation of liquidity coefficients showed a tendency to reduce the level of coverage of liabilities by liquid assets of banking institutions, to reduce the solvency of the banking system and worsen the ability of banks to fulfill their obligations. Improving their reliability should be one of the primary strategic tasks of all banks.

Authors:   Uman National University of Horticulture, Vlasyuk S. A.
Published: August 2021

Insurance represents the most efficient risk management instrument that can protect both individuals and business entities from financial risks arising from various unforeseen situations. In turn, expanding the horizons of the insurance market requires clarity and coherence in the activities of insurance companies, and therefore studying the factors that directly affect the management of insurance organizations appears relevant. It is found that one of the forms of risk control is insurance management, which includes the detection, assessment and intervention of risks, that is, a defense strategy for preparing for the unexpected events, as it is regulated by normative legal acts, and the implementation of principles and doctrines that are generally accepted. It is identified that the main methods of insurance management, such as avoidance, preservation, distribution, transfer, prevention and reduction of losses, can be applied to all areas of activity of both individuals and business entities, and can pay off in the long term. The development of the insurance market in Ukraine in the future is possible due to the introduction of an effective mechanism of insurance management based on system analysis and effective control at macro and micro levels. By implementing a risk management plan and considering various potential risks or events before they occur, economic entities can save their own money and protect their future by timely setting of certain contours in order to avoid potential threats, minimize their impact in case of their occurrence, and cope with the results.

Published: August 2021

The article is aimed at closer defining the theoretical provisions for improving the management of financial stability of a commercial bank and assessing its current state in the context of the impact of destabilizing factors. Scientific approaches to the definition of the category of «financial stability of a commercial bank» are considered, which allows to detail its characteristic features and form a comprehensive idea of the financial stability of a commercial bank as a system category, the timely estimation of benchmarks of which allows minimizing the impact of specific and systematic risks to the economic environment in conditions of high uncertainty. The article systematizes the normative legal acts regulating all potential aspects of the commercial bank's financial stability shift due to changes in the structure of capital, liquidity, solvency, credit risks and being part of the information provision for the analysis of financial stability of a commercial bank. The classification of factors influencing the financial stability of a commercial bank is generalized. The influence of the epidemiological crisis associated with the spread of COVID-19 on key benchmarks of the banking system in terms of assessing the financial stability of the banking institution is examined. The dynamics of changing the proportion of non-performing loans of commercial banks of Ukraine is analyzed, as lending creates the basis for ensuring a balance between temporarily free funds and the amount of resources required at the microlevel of the financial system for sustainable development. Particular attention is paid to the aspects of balance and sustainability of the resource base of the commercial bank, which led to a thorough analysis of the liabilities of the banking system from the position of influencing the financial stability of a commercial bank.

Published: August 2021

The article is aimed at establishing a modern vector of development of pawnshops in Ukraine. The current state of the pawnshop loans market is analyzed and its detailed analysis is carried out from the point of view of opportunities and threats at the macrolevel and strengths and weaknesses at the microlevel. In the course of a SWOT analysis of the state of the pawnshop loans market, the relative balance of prospects and challenges of economic, social and political nature, which have an impact on the functioning of pawnshops, is determined. The hypothesis about the significant impact on the development of pawnshops in Ukraine such factors as the solvency of the population and the volume of economic development (in terms of GDP per capita) is put forward. A regressive model of development of the pawnshop lending market is formed, the economic interpretation of which is the possibility of increasing the volume of issued pawnshop loans with an increase in the volume of average monthly incomes of citizens, and their reduction is possible with an increase in the unemployment rate in Ukraine and a build-up in the level of GDP per capita. It is assumed that the results of the model reflect a critical limit of the cumulative impact of selected socio-economic factors, when low incomes of the population with high unemployment and slow GDP growth cause an unconventional effect – a reduction in the volume of the short-term lending market, characterized by the effect of behavioral finances, when it is more important for borrowers to avoid unjustified costs than to receive short-term benefits. It is emphasized that the possibilities of development of pawnshops are concentrated in the vector of their qualitative renewal: the formation of a legislative basis for self-regulation of the market, deepening of work to improve financial literacy of the population, in particular, public awareness of the risks of obtaining loans in pawnshops.

The main aim of this article is to research the existing scientific concepts for considering the essence of the category of «fiscal instrument» and substantiate the essence of this definition. It is noted that there is an urgent issue of deepening the provisions formed and also developing further provisions in the field of functioning of the fiscal system, searching for the optimal model when developing such a system. Thus, there is a need for the implementation of new researches in this sphere to deepen the theoretical aspects of the functioning of the fiscal system, including the need to substantiate the content of certain scientific categories and specify existing ones. The article considers the essence of the category of «economic instrument», analyzes the existing concepts of research of this definition. It is determined that this type of instruments is an integral part of the whole mechanism of the State regulation of the national economy, stimulation of the development of certain sectors of the economy, management of the State property. This allowed us to continue to study the role of various types of economic instruments in ensuring the efficient functioning of the national economy, in particular fiscal ones. It is also determined that in the vast majority of cases, using the category of «fiscal instrument», scientists often identify it with the definition of «tax instrument». In a significant number of works when considering derivative scientific concepts from the word «fiscal», it is also not enough attention to specify the content of fiscal instruments. Thus, the article proposes to consider the content of the category of «fiscal instrument» as follows: fiscal instrument – a means used to save financial resources of economic entities in order to generate the State budget revenues.

Published: August 2021

This article is aimed at analyzing and systematizing the existing approaches to determining the essence of brand management, as well as its place in the system of related categories of marketing. At that, within the terms of the set goal, the task is to reduce the «conceptual» load on the theoretical base in the marketing sphere by analyzing and structuring current categories, and not creating new ones. During the research, two tangent categories with brand management – «management of brand» and «branding» – were distinguished and their relationship with brand management was determined. Analyzing the theoretical positions of leading specialists in the sphere of marketing, opinions of foreign and domestic scientists, the presence of identifiable concepts of «brand of management» and «management of brand» was specified, which is not true. Management of brand is a component of brand management, which consists in systematic activity using existing and searching for new resources and brand positioning tools. A concise and logical scheme is proposed that reveals the essence of brand management and the main stages of its implementation in the context of this issue. The scheme also reveals the place of branding in the brand management system, namely: at the stages of brand creation and its development /modification. It is determined that brand management directly correlates with the strategy of the enterprise and affects its implementation. The brand development strategy should correspond to the philosophy of the enterprise, its mission and organizational and corporate culture. It is emphasized that brand management is one of the main directions in the strategic management of the enterprise, as it allows to capitalize the value of branded assets and increase its competitiveness. Prospects for further research in this direction are to study the features of modern brand management and tools for its effective implementation.

The article examines the essence of staff motivation, analyzes the opinions of scholars on this issue. It is determined that among scholars there is no consensus on the interpretation of the term of «staff motivation». On the basis of extant researches the authors' own interpretation of motivation is proposed. The trends of wage development at Ukrainian enterprises are analyzed and conclusions are drawn based thereupon. One of the most important factors in the successful functioning of enterprise is the motivation of staff, which is the main factor of successful competitiveness. The process of motivation is largely determined by the needs that initiate it. If the needs of individuals coincide with the needs of the enterprise, employees will invest their efforts for their own satisfaction, which will increase productivity, reduce costs and ensure high quality of products, which altogether will increase profits and ensure the competitive position of the company in the market. It is emphasized that in the formation of motivation of staff it is necessary to fulfill the following conditions: study the dynamics of wage level; there should be a direct relation between the level of wages and the number and quality of labor results; the presence of a structure of personal income; material support of available money income, etc. Negative motivation is more effective if it is applied immediately after undesirable actions of the employee. The later the sanctions are applied, the less they affect the behavior of the employee. Due to the skillful use of negative motivation (its fair character and the dosage of the intensity of stimulus, a specific situation), it is possible to achieve a change in the behavior of employees for the better. Methods of improvement of the motivation system, which is aimed at increasing the competitiveness of the enterprise, have been developed. Staff motivation today is one of the most important factors in the successful functioning of enterprise, so management be very interested in the successful construction of a system that will meet the needs of employees.

In the current conditions of rapid digitalization of the worldwide space, taking into account global factors, which are being forced, including such «black swans» as the COVID-19 pandemic, the issues of e-commerce development in the context of certain regions are being activated. The article is aimed at studying and identifying the features and trends of e-commerce development in the Latin American region, a detailed analysis of Brazil, Mexico and Argentina as the largest markets in the region. To achieve this aim, the methods of scientific abstraction, analysis and synthesis, statistical analysis, comparison, structural and logical generalization were used. The article determines that, given the large population of the region with a significant stratification of society, the region has seen a sharp increase in the e-commerce market, including by means of the mass digitalization of the end user to meet the need for remote work and training during the pandemic. Most researchers distinguish the markets of Brazil, Mexico and Argentina as the largest in the region. There is a significant increase in the presence of regional and global platforms, with an emphasis on the problem of disproportionately large volume of Asian products sold by global platforms. The increase in the volume of trading platforms can have a beneficial impact on the improvement of logistics infrastructure in the region, which is currently one of the key problems. Among the existing problems, experts also indicate a low level of penetration of banking services and a high degree of cash circulation. Due to the specifics of the banking sector, not all local cards are valid on international trading platforms, which is one of the deterrent factors for the development of e-commerce. Based on statistical analysis, it is determined that in the current realities of the Latin American region, the process of digitalization of all e-commerce market participants is experienced while maintaining trends in the steady growth of key indicators of Internet commerce. This characterizes the region as promising in terms of increasing market volumes, the number of Internet consumers, the level of Internet penetration, the modernization of the banking sector and changes in legislation. At the same time, it is identified that in the presence of problems of the shadow economy, a low degree of public confidence in the banking sector, the preservation of a significant disparity in the incomes of categories of the population, there is a need to revalue the prospects and conditions for the further development of the e-commerce market in the post-pandemic period.

The article is concerned with analyzing the experience of implementing innovative instruments for the development of agrarian insurance in the world. The article is aimed at defining the latest global trends in the development of insurance in the agricultural sector in order to introduce and implement effective insurance mechanisms in domestic agricultural practice. In the course of the research, the following methods were used: dialectic cognition, abstract-logical approach – in generalization of research results and formulation of conclusions; scientific foresight – in terms of formation of directions for development of the agricultural insurance market in the world. Types of agricultural insurance are defined as follows: private agricultural insurance, the State-based agricultural insurance, non-commercial agricultural insurance. It is noted that the world experience of introducing new insurance programs under the influence of globalization transformations in the global agri-food markets demonstrates new opportunities and challenges for the development of agricultural insurance in Ukraine and requires further scientific researches. A number of reasons have been identified that hinder the development of the agricultural insurance market world-wide. A discrepancy between the dynamics of the development of the agricultural sector of the economy and the volume of agricultural insurance in the world is identified, also the underdevelopment of the insurance instrumentarium in the full extent is specified. It is emphasized that the development, implementation and success of agricultural insurance programs require a high level of coordination, cooperation and common vision. The conclusion on the extant problems of development of the insurance market in Ukraine, caused by the lack of a clear strategy for its development along with no consideration of the interests of all its participants, is substantiated.
Regional Innovation Ecosystems in Ukraine
Authors:   National University of Kyiv-Mohyla Academy, Kobernyk A. O.
Published: August 2021

The article substantiates the prerequisites, prospects and advantages of creating an innovation ecosystem at different levels of its formation. The main approaches to defining the essence of the concept of innovation ecosystems in both domestic and foreign specialized literature and their adaptability to the regional level are analyzed and grouped. The harmonious innovation ecosystem is a sign of a progressive society, which is identified by the symbiotic functioning of people and organizations, the result of which is the production of conscious innovations. The author outlines the stages of formation of the regional innovation ecosystem, the circle of its participants and ways of their interaction. For each stage, the procedures for its implementation, the main characteristic features and processes of transition from one to another are determined. The main feature of the creation and functioning of the regional ecosystem is the stable, constant interaction of its participants with educational and scientific institutions, as well as the adaptability of these institutions to the variability of the external environment. The article describes certain elements of foreign experience in the development of regional ecosystems and their implementation in Ukraine. Awareness of the existence or prerequisites for creating an effective regional ecosystem is the first step towards effective regional management and activation of the potential of the national economy. On the one hand, in the context of decentralization, local self-government bodies get maximum freedom in creating organizational elements of the regional innovation ecosystem, supporting scientific and human resources and the communication business environment. The author emphasizes that without the State support it is impossible to create conditions for the protectionism of innovation activity, to activate investment potential, to stimulate the necessary forms and methods of financing the relevant activity. Therefore, work at the regional level in terms of innovation should be carried out simultaneously following two directions of the hierarchy: from bottom up and from top to bottom in constant cooperation and coordination of own actions. As a result, priority directions of the State and regional support for the development of regional innovation ecosystems on the basis of the main specific platforms or technologies are substantiated.

Published: August 2021

The article is aimed at developing proposals for the activation of the processes of modernization of fixed assets of municipal heat and power economy. The existing state of investment activity in the field of heat supply is analyzed, «bottlenecks» are identified and proposals for the revival of the processes of modernization of heat supply systems are developed. All enterprises of municipal heat and power economy are characterized by a large level of wear of fixed assets. Low efficiency coefficient of heat-generating equipment and high heat loss during transportation (due to the degeneration of pipelines) is one of the reasons for high tariffs for heat energy with low quality and reliability of heat supply. The only way out of the current situation is the activation of investment activities of communal heat and power enterprises, mass reconstruction and modernization of equipment involved in the production, transportation and supply of heat energy. Analyses of annual reports of heat supply enterprises for 2014-2020 allowed to identify the following shortcomings in the management of investment activities: shortage of investment resources in communal heat and power enterprises; orientation in the implementation of investment activities only towards the use of deductions for depreciation; imperfection of tariff, budget and tax policy in the course of the State support of investment processes. As measures to intensify the investment activity of communal heat and power enterprises, it is proposed the following: revaluation of the cost of fixed assets of municipal heat and power enterprises; establishing the procedure according to which all accrued depreciation is included in the sources of financing of the investment program; granting tax benefits to communal utility enterprises on income tax and land fees (the provision of such tax benefits will not affect the financial condition of the community: reducing income corresponds with a decrease in the cost of providing financial assistance to a communal utility heat supply enterprise); improvement of normative legal acts regulating the issues of substantiation of tariffs for heat energy and investment programs of heat supplying enterprises, as well as control over the implementation.

The article generalizes the main external environment factors that affect the development of export-import activities of domestic industrial enterprises in modern conditions; the external environment factors that directly affect this activity are distinguished. The expediency of analysis of lag influence of external environment factors is substantiated. It is recommended to carry out the process of analysis of external environment factors that affect the development of export-import activity of industrial enterprises in the following sequence of stages: 1) theoretical-logical analysis of the main factors of external environment impact on the development of export-import activity in the country; 2) analysis of external environment factors that directly affect the development of this activity of enterprises; 3) analysis of the main tendencies in the dynamics of the directly affecting external environment factors; 4) determination of causal relationships in the system of the directly affecting external environment factors; 5) determination of dependence of the volume of industrial products sold on the directly affecting external environment factors; 6) determination of the lag influence of external environment factors that directly affect the development of export-import activities of industrial enterprises; 7) development of administration measures to strengthen the development of export-import activities of domestic industrial enterprises. The above specified sequence of stages facilitates the organization of the process of determining factors and directions of development of export-import activity in Ukraine. The article proposes a list of analytical instruments that should be used in the analysis of external environment factors that affect the development of export-import activities of industrial enterprises.

This paper attempts to come up with a proposed configuration of Multilevel inverters with a lesser number of switches that are smaller in size, lesser in cost and with a higher efficiency. Designing an inverter topology with a lesser number of switches and proper control technique is the major challenge. cascaded H-Bridge (CHB) topology are more popular among the existing configurations of multilevel inverters (MLI). Even though it can produce more levels, it needs to accommodate a huge number of switches for higher levels. The focus of this paper is to reduce the number of components for the same voltage level of cascaded H- Bridge configuration. In addition to that, generating the gating pulses for the switches is difficult when there is an asymmetry in the switches. A new symmetrical series/parallel configuration is proposed with reduced switch count and the pulse width modulation (PWM) technique is implemented with digital logic to generate the required gating pulses for the switches. The total harmonic distortion (THDI) of the output current is reduced with this PWM technique. The simulation has been carried out in MATLAB/Simulink software for both R (resistive) and R-L (resistive -inductive) loads.

One of the most difficult speech recognition tasks is accurate recognition of human-to-human communication. Advances in deep learning over the last few years have produced major speech improvements in recognition on the representative Switch-board conversational corpus. Word error rates that just a few years ago were 14% have dropped to 8.0%, then 6.6% and most recently 5.8%, and are now believed to be within striking range of human performance. This raises two issues - what is human performance, and how far down can we still drive speech recognition error rates? The main objective of this article is the development of a comparative study of the performance of Automatic Speech Recognition (ASR) algorithms using a database made up of a set of signals created by female and male speakers of different ages. We will also develop techniques for the Software and Hardware implementation of these algorithms and test them in an embedded electronic card based on a reconfigurable circuit (Field Programmable Gate Array FPGA). We will present an analysis of the results of classifications for the best Support Vector Machine architectures (SVM) and Artificial Neural Networks of Multi-Layer Perceptron (MLP). Following our analysis, we created NIOSII processors and we tested their operations as well as their characteristics. The characteristics of each processor are specified in this article (cost, size, speed, power consumption and complexity). At the end of this work, we physically implemented the architecture of the Mel Frequency Cepstral Coefficients (MFCC) extraction algorithm as well as the classification algorithm that provided the best results.
