    Cochleogram-Based Speech Emotion Recognition With the Cascade of Asymmetric Resonators With Fast-Acting Compression Using Time-Distributed Convolutional Long Short-Term Memory and Support Vector Machines
    (Mdpi, 2025) Parlak, Cevahir
    Feature extraction is a crucial stage in speech emotion recognition applications, and filter banks with their related statistical functions are widely used for this purpose. Although Mel filters and MFCCs achieve outstanding results, they do not perfectly model the structure of the human ear, as they use a simplified mechanism to simulate the functioning of human cochlear structures. The Mel filters system is not a perfect representation of human hearing, but merely an engineering shortcut to suppress the pitch and low-frequency components, which have little use in traditional speech recognition applications. However, speech emotion recognition classification is heavily related to pitch and low-frequency component features. The newly tailored CARFAC 24 model is a sophisticated system for analyzing human speech and is designed to best simulate the functionalities of the human cochlea. In this study, we use the CARFAC 24 system for speech emotion recognition and compare it with state-of-the-art systems using speaker-independent studies conducted with Time-Distributed Convolutional LSTM networks and Support Vector Machines, with the use of the ASED and the NEMO emotional speech dataset. The results demonstrate that CARFAC 24 is a valuable alternative to Mel and MFCC features in speech emotion recognition applications.

    Do We Learn To Internalize Stigma From Our Parents? Comparison of Internalized Stigmatization in Adolescents Diagnosed With Adhd and Their Parents
    (Mdpi, 2022) Dikec, Gul; Bilac, Oznur; Kardelen, Cansin; Sapmaz, Sermin Yalin
    This study compared internalized stigmatization levels of adolescents diagnosed with attention deficit and hyperactivity disorder (ADHD) with those of their parents. The study's data were collected from 107 adolescents diagnosed with ADHD and their parents between July 2020 and March 2021. The adolescents were followed up in the child and adolescent psychiatry outpatient clinic of a university hospital in western Turkey. The information forms for adolescents and parents, the Internalized Stigma of Mental Illness Scale-Adolescent Form (ISMI-AF) and the Parental Internalized Stigma of Mental Illness Scale (PISMI), were used to collect the data. There was no statistically significant difference between the total scores of internalized stigma and subscale mean scores of the adolescents and their parents (p > 0.05); only the subscale scores for stereotype endorsement were found to be significantly different (p < 0.05). PISMI scores affected ISMI-AF scores, which can be interpreted as parents' perspectives and attitudes toward stigmatization affecting adolescents. For ADHD, whose frequency is increasing daily, intervention studies should be conducted to reduce adolescents' and parents' internalized stigma and to enhance the educational outcomes of adolescents.
