Abstract
Alcohol addiction can lead to health and social problems. It can also affect people's emotions. Emotion plays a key role in human communications. It is important to recognize the people's emotions at the court and infer the association between the people's emotions and the alcohol addiction. However, it is challenging to recognize people's emotions efficiently in the courtroom. Furthermore, to the best of our knowledge, no existing work is about the association between alcohol addiction and people's emotions at court. In this paper, we propose a deep learning framework for predicting people's emotions based on sound perception, named ResCNN-SER. The proposed model combines several neural network-based components to extract the features of the speech signals and predict the emotions. The evaluation shows that the proposed model performs better than existing methods. By applying ResCNN-SER for emotion recognition based on people's voices at court, we infer the association between alcohol addiction and the defendant's emotion at court. Based on the sound source data from 54 trial records, we found that the defendants with alcohol addiction tend to get angry or fearful more easily at court comparing with defendants without alcohol addiction.
Highlights
Emotion perception plays a key role in human communications and is of interest to a range of disciplines, including psychology, psychiatry, and social neuroscience
We analyze the association between alcohol addiction and people’s emotions at court using the proposed method ResCNN-speech emotion recognition (SER)
To evaluate the performance of ResCNN-SER, we test our model on the Emo-DB dataset, which is derived from Berlin Emotional Database (Burkhardt et al, 2005)
Summary
Emotion perception plays a key role in human communications and is of interest to a range of disciplines, including psychology, psychiatry, and social neuroscience. Emotions may influence thinking patterns, decision-making, and talking. The talking and thinking pattern of defendants are critical for judges to make a decision. It is important to study the role of the defendants’ emotions at the court and which factors may affect the defendants’ emotions. Alcohol addiction may impact several aspects of people’s daily life, including people’s emotions. The existing study shows that emotions are likely to affect court judgment when a particular information processing style is active (Nunez et al, 2016). Studying the relation between alcohol addiction and the defendants’ emotions at court can help to answer several key questions. Does alcohol addiction affect the defendants’ emotions? Does alcohol addiction affect the defendants’ emotions? How can we avoid the bias resulting from the emotions of people, such as lawyers, judges, defendants, plaintiffs, and so on?
