Using artificial neural nets to compare different vocal tract models
نویسندگان
چکیده
In this study artificial neural nets (ANN), relating articulation to acoustic features, are used as tools to investigate the ability of different vocal-tract models to describe the vocal tract. The vocal tract models are compared by means of a test material common to all evaluations. Different ANN configurations are used and investigated. Aspects of analysing natural speech signal with ANNs, trained on synthetic speech, are discussed. In addition, some effects of the speaker-dependency of the ANNs are investigated. The models are tested on synthetic speech (based on X-ray data of Swedish vowels) and natural speech from different speakers.

EVALUATION OF CONCRETE COMPRESSIVE STRENGTH USING ARTIFICIAL NEURAL NETWORK AND MULTIPLE LINEAR REGRESSION MODELS
In the present study, two different data-driven models, artificial neural network (ANN) and multiple linear regression (MLR) models, have been developed to predict the 28 days compressive strength of concrete. Seven different parameters namely 3/4 mm sand, 3/8 mm sand, cement content, gravel, maximums size of aggregate, fineness modulus, and water-cement ratio were considered as input variables...

Accurate estimation of evaporation is important for design, planning and operation of water systems. In arid zones where water resources are scarce, the estimation of this loss becomes more interesting in the planning and management of irrigation practices. This paper investigates the ability of artificial neural networks (ANNs) technique to improve the accuracy of daily evaporation estimation....
متن کاملUsing emotional intelligence to predict job stress: Artificial neural network and regression models
Introduction: These days, there is a consensus that emotional intelligence plays an important role in the success of individuals in different areas of life. Persons with higher emotional intelligence had lower stress in dealing with demands and pressures in the workplace. The purpose of this study was to use artificial neural network to predict job stress and to compare the performance of this ...

متن کاملDiscriminating Neutral and Emotional Speech using Neural Networks
In this paper, we address the issue of speaker-specific emotion detection (neutral vs emotion) from speech signals with models for neutral speech as reference. As emotional speech is produced by the human speech production mechanism, the emotion information is expected to lie in the features of both excitation source and the vocal tract system. Linear Prediction residual is used as the excitati...
