Efficient and effective strategies for cross-corpus acoustic emotion recognition
Kaya, Heysem; Karpov, Alexey A. (Elsevier, 2018)An important research direction in speech technology is robust cross-corpus and cross-language emotion recognition. In this paper, we propose computationally efficient and performance effective feature normalization ... -
Emotion, age, and gender classification in children's speech by humans and machines
Kaya, Heysem; Salah, Albert Ali; Karpov, Alexey A.; Frolova, Olga; Grigorev, Aleksey; Lyakso, Elena (Academic Press Ltd- Elsevier Science Ltd, 2017)In this article, we present the first child emotional speech corpus in Russian, called EmoChildRu, collected from 3 to 7 years old children. The base corpus includes over 20 K recordings (approx. 30 h), collected from 120 ... -
Fusing Acoustic Feature Representations for Computational Paralinguistics Tasks
Kaya, Heysem; Karpov, Alexey A. (Isca-Int Speech Communication Assoc, 2016)The field of Computational Paralinguistics is rapidly growing and is of interest in various application domains ranging from biomedical engineering to forensics. The INTERSPEECH ComParE challenge series has a field-leading ... -
Hierarchical Two-Level Modelling of Emotional States in Spoken Dialog Systems
Verkholyak, Oxana Vladimirovna; Fedotov, Dmitrii; Kaya, Heysem; Zhang, Yang; Karpov, Alexey A. (IEEE, 2019)Emotions occur in complex social interactions, and thus processing of isolated utterances may not be sufficient to grasp the nature of underlying emotional states. Dialog speech provides useful information about context ... -
Introducing Weighted Kernel Classifiers for Handling Imbalanced Paralinguistic Corpora: Snoring, Addressee and Cold
Kaya, Heysem; Karpov, Alexey A. (Isca-Int Speech Communication Assoc, 2017)The field of paralinguistics is growing rapidly with a wide range of applications that go beyond recognition of emotions, laughter and personality. The research flourishes in multiple directions such as signal representation ... -
LSTM based Cross-corpus and Cross-task Acoustic Emotion Recognition
Kaya, Heysem; Fedotov, Dmitrii; Yesilkanat, Ali; Verkholyak, Oxana Vladimirovna; Zhang, Yang; Karpov, Alexey A. (Isca-Int Speech Communication Assoc, 2018)Acoustic emotion recognition is a popular and central research direction in paralinguistic analysis, due its relation to a wide range of affective states/traits and manifold applications. Developing highly generalizable ... -
Modeling short-term and long-term dependencies of the speech signal for paralinguistic emotion classification
Verkholyak, Oxana Vladimirovna; Kaya, Heysem; Karpov, Alexey A. (St. Petersburg Institute for Informatics and Automation of the Russian Academy of Sciences, 2019)Recently, Speech Emotion Recognition (SER) has become an important research topic of affective computing. It is a difficult problem, where some of the greatest challenges lie in the feature selection and representation ... -
Robust Acoustic Emotion Recognition Based on Cascaded Normalization and Extreme Learning Machines
Kaya, Heysem; Karpov, Alexey A.; Salah, Albert Ali (Springer International Publishing Ag, 2016)One of the challenges in speech emotion recognition is robust and speaker-independent emotion recognition. In this paper, we take a cascaded normalization approach, combining linear speaker level, non-linear value level ...
