Automatic detection of stress in speech

MSAS: An M-mental health care System for Automatic Stress detection

Tumor Detection and Morphology Assessment in the Liver Tissue Using an Automatic Tactile Robot

In this paper an automatic examination robot was developed to improve the process of cancer detection, tumor localization and geometrical shape diagnosis. A uniformly distributed compressive load was applied to the top tissue surface and the resultant mechanical stress was measured that was employed for the tumor diagnosis task. The experimental examinations were performed on the soft tissue of...

Designing and implementing a system for Automatic recognition of Persian letters by Lip-reading using image processing methods

For many years, speech has been the most natural and efficient means of information exchange for human beings. With the advancement of technology and the prevalence of computer usage, the design and production of speech recognition systems have been considered by researchers. Among this, lip-reading techniques encountered with many challenges for speech recognition, that one of the challenges b...

A Database for Automatic Persian Speech Emotion Recognition: Collection, Processing and Evaluation

Abstract   Recent developments in robotics automation have motivated researchers to improve the efficiency of interactive systems by making a natural man-machine interaction. Since speech is the most popular method of communication, recognizing human emotions from speech signal becomes a challenging research topic known as Speech Emotion Recognition (SER). In this study, we propose a Persian em...

Using automatic stress extraction from audio for improved prosody modelling in speech synthesis

Generating proper and natural sounding prosody is one of the key interests of today’s speech synthesis research. An important factor in this effort is the availability of a precisely labelled speech corpus with adequate prosodic stress marking. Obtaining such a labelling constitutes a huge effort, whereas interannotator agreement scores are usually found far below 100%. Stress marking based on ...

Robust Emotional Stressed Speech Detection Using Weighted Frequency Subbands

The problem of detecting psychological stress from speech is challenging due to differences in how speakers convey stress. Changes in speech production due to speaker state are not linearly dependent on changes in stress. Research is further complicated by the existence of different stress types and the lack of metrics capable of discriminating stress levels. This study addresses the problem of...
