On the development of an automatic voice pleasantness classification and intensity estimation system

چکیده
In the last few years, the number of systems and devices that use voice based interaction has grown significantly. For a continued se of these systems, the interface must be reliable and pleasant in order to provide an optimal user experience. However there are urrently very few studies that try to evaluate how pleasant is a voice from a perceptual point of view when the final application s a speech based interface. In this paper we present an objective definition for voice pleasantness based on the composition of a epresentative feature subset and a new automatic voice pleasantness classification and intensity estimation system. Our study is ased on a database composed by European Portuguese female voices but the methodology can be extended to male voices or to ther languages. In the objective performance evaluation the system achieved a 9.1% error rate for voice pleasantness classification nd a 15.7% error rate for voice pleasantness intensity estimation. 2012 Elsevier Ltd.

In the last few years the number of systems and devices that use voice based interaction as grown significantly. For a daily use of such systems the interaction must be always pleasantness in order to provide an optimal user experience. In this paper we present a new automatic voice pleasantness classification system based on prosodic and acoustic patterns of voice preference. The classificatio...
متن کاملDevelopment of an Automatic Land Use Extraction System in Urban Areas using VHR Aerial Imagery and GIS Vector Data
Lack of detailed land use (LU) information and efficient data collection methods have made the modeling of urban systems difficult. This study aims to develop a novel hierarchical rule-based LU extraction framework using geographic vector and remotely sensed (RS) data, in order to extract detailed subzonal LU information, residential LU in this study. The LU extraction system is developed to ex...

Manual fingerprint classification algorithms are very time consuming, and usually not accurate. Fast and accurate fingerprint classification is essential to each AFIS (Automatic Fingerprint Identification System). This paper investigates a fingerprint classification algorithm that reduces the complexity and costs associated with the fingerprint identification procedure. A new structural algorit...
متن کاملAutomatic Interpretation of UltraCam Imagery by Combination of Support Vector Machine and Knowledge-based Systems
With the development of digital sensors, an increasing number of high-resolution images are available. Interpretation of these images is not possible manually, which necessitates seeking for practical, fast and automatic solutions to solve the environmental and location-based management problems. The land cover classification using high-resolution imagery is a difficult process because of the c...
