Abstract:

Pigs have become important animal models in voice research. Several objective parameters exist to characterize the pig voice, but it is not clear which of them are sensitive to the impaired voice quality after laryngeal injury or surgery. In order to conduct meaningful voice research in pigs, it is critical to have standard functional voice outcome measures that can distinguish between normal and impaired voices. For this reason, we investigated 17 acoustic parameters before and early after surgery in three Yucatan mini pigs. Four parameters showed consistent changes between pre- and post-surg

Abstract:

Computer-based analysis systems are increasingly available for the clinical assessment of speech and voice functions. These systems have the potential to provide immediate quantitative information to assist clinical assessment and treatment. The Multi-Dimensional Voice Program (MDVP) is a computer program that can calculate as many as 33 acoustic parameters from a voice sample. The MDVP appears to have potential for rapid quantitative assessments of voice in both research and clinical applications. This report evaluates the robustness and reliability of MDVP for vocal analyses of 32 individual

Abstract:

TPS12139 Background: Assessing of frailty is essential not only in older patients with cancer, because frailty changes management of cancer therapy. Same is true for the routine assessment of distress to identify patient suffering and initiate adequate symptom control or psychosocial interventions. Here we present new potential method of frailty and distress assessment with digital voice analysis as a proof of concept trial. (NCT requested pending, DIVAN-1). Methods: Adult patients with the diagnosis of active incurable cancer can be enrolled into this study. Every participant will describe tw

Abstract:

AbstractIllegal logging is a global concern, associated with severe negative environmental, social and economic impacts, such as deforestation, degradation of biodiversity and loss of government revenues. Despite recent international efforts to combat illegal logging activities, the problem remains widespread. While the academic literature on the subject is extensive, little systematic research has been devoted to analysing the causes of illegal logging. Here, this knowledge gap is addressed with a cross-national assessment of factors hypothesized to impact illegal logging. The logistic regres

Abstract:

Singing Voice separation is a very important method that helps people to obtain a vocal or accompaniment for further usage like music composing. In this paper, I developed a Song accompaniment separation application based on Convolutional neural network Unet model and Deep learning (DL). Basically, the U-net convolutional network is applied to the two-dimensional spectrum of a music audio in order to achieve a more precise separation effect. During this deep learning process, a significant amount of data was inserted into the model to get the best fit parameters. Then, after all, the model can

Abstract:

The subject of the study is the potential of branding, as an instrument of economic development of the branding object, for its possible application to non-traditional objects. The purpose of the study is to analyze the new object of branding – «the voice» and determine its role in promoting the national brand of the country. The practical implementation of the research results is to broaden the theoretical horizons of branding theory and to use the new object of branding - voice in the creation and promotion of a national brand of the country.

Abstract:

The current scientific task of quantitative assessment of the effectiveness of existing and developing biometric systems is considered. Known works on the comparative analysis of biometric systems, as a rule, discuss their characteristics and principles of operation. However, there is no data on the quantitative assessment of the effectiveness of biometric systems, of which there are quite a few on the market. In the proposed work, an attempt is made to eliminate this shortcoming. The development is based on a systematic approach, namely the efficiency/cost criterion. When evaluating efficienc

Method Quantitative and transversal study. 47 speakers of Brazilian Portuguese of different genders were recorded. Recordings included sustained vowel emission, connected speech, and the expressive recital of a poem. Subsequently, four scripts were used in Praat to extract 16 acoustic measurements related to prosody.

Abstract Managing forest disturbances can be complicated by diverse human community responses. Interviews and quantitative analysis of mail surveys were used to assess risk perceptions and community actions in response to forest disturbance by spruce bark beetles. Despite high risk perception of immediate threats to personal safety and property, risk perceptions of broader threats to community and ecological well-being were found to be more likely to influence participation in community action. Results imply that increased dialogue between resource managers and local community residents contri

Abstract:

Auditory perceptual evaluation is considered the gold standard for assessing voice quality, but its reliability is limited due to inter-rater variability and coarse rating scales. This study investigates a continuous, objective approach to evaluate hoarseness severity combining machine learning (ML) and sustained phonation. For this purpose, 635 acoustic recordings of the sustained vowel /a/ and subjective ratings based on the roughness, breathiness, and hoarseness scale were collected from 595 subjects. A total of 50 temporal, spectral, and cepstral features were extracted from each recording

Abstract:

Background: Take home, or open-book, examinations (OBE) are designed to be completed at a location of student choice, whilst providing comprehensive assessment of learning outcomes. Supporters of OBE refer to their authenticity, in that they reflect real-world practice where use of external resources is routine and encouraged. A contrasting view is that efficient practice requires a solid base of knowledge upon which to draw. The aim of this evaluation was to elicit learners’ perceptions of the open-book, unproctored examination approach; we sought student views on authenticity, assessment pre
