Acoustic analysis of vocal fatigue in professional voice users
vocal fatigue is a voice symptom which is frequently reported by professional voice users. teachers, singers, actors and other professions that require prolonged voice use are especially at-risk group. the vocal fatigue results in auditory perceptual and acoustic changes in the voice signal and can lead to serious pathological conditions. the present study has examined acoustic manifestations o...
متن کاملOperator Fatigue Estimation Using Heart Rate Measures
The growing number of fatigue related accidents in recent years has become a serious concern. Accidents caused by fatigue in transportation and in mining operations involving heavy equipment can lead to substantial damage and loss of human life. Preventing such fatigue related accidents is highly desirable, but requires techniques for continuously estimating and predicting the operator’s alertn...
متن کاملEstimation of Source Location Using Curvature Analysis
A quadratic surface can be fitted to potential-field data within 3×3 windows, which allow us to calculate curvature attributes from its coefficients. Phillips (2007) derived an equation depending on the most negative curvature to obtain the depth and structural index of isolated sources from peak values of special functions. They divided the special functions into two categories: Model-specific...
متن کاملMuscle Fatigue Analysis Using OpenSim
In this research, attempts are made to conduct concrete muscle fatigue analysis of arbitrary motions on OpenSim, a digital human modeling platform. A plug-in is written on the base of a muscle fatigue model, which makes it possible to calculate the decline of forceoutput capability of each muscle along time. The plug-in is tested on a three-dimensional, 29 degree-of-freedom human model. Motion ...
متن کاملSinging Voice Separation Using Deep Neural Networks and F0 Estimation
Deep Neural Networks (DNN) have become a popular approach for speech enhancement, and singing voice separation. DNNs are typically trained to estimate a timefrequency mask using ground truth examples. In this submission, we combine DNN estimation as a first step with traditional refinement via F0 estimation, using the YINFFT algorithm.
