This basically follows either a feature-level or decision-level strategy. In all likelihood, while features from several modalities may enhance the classification performance, they might exhibit high dimensionality and make the learning process complex for the most used machine learning algorithms. To overcome issues of feature extraction and multi-modal fusion, hybrid fuzzy-evolutionary computation methodologies are employed to demonstrate ultra-strong capability of learning features and dimensionality reduction. This paper proposes a novel multi-modal emotion aware system by fusing speech with EEG modalities. Firstly, a mixing feature set of speaker-dependent and independent characteristics is estimated from speech signal. Further, EEG is utilized as inner channel complementing speech for more authoritative recognition, by extracting multiple features belonging to time, frequency, and time\u2013frequency. For classifying unimodal data of either speech or EEG, a hybrid fuzzy c-means-genetic algorithm-neural network model is proposed, where its fitness function finds the optimal fuzzy cluster number reducing the classification error. To fuse speech with EEG information, a separate classifier is used for each modality, then output is computed by integrating their posterior probabilities. Results show the superiority of the proposed model, where the overall performance in terms of accuracy average rates is 98.06%, and 97.28%, and 98.53% for EEG, speech, and multi-modal recognition, respectively. The proposed model is also applied to two public databases for speech and EEG, namely: SAVEE and MAHNOB, which achieve accuracies of 98.21% and 98.26%, respectively.<\/jats:p>","DOI":"10.3390\/info10070239","type":"journal-article","created":{"date-parts":[[2019,7,11]],"date-time":"2019-07-11T11:28:28Z","timestamp":1562844508000},"page":"239","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Multi-Modal Emotion Aware System Based on Fusion of Speech and Brain Information"],"prefix":"10.3390","volume":"10","author":[{"given":"Rania M.","family":"Ghoniem","sequence":"first","affiliation":[{"name":"Department of Computer, Mansoura University, Mansoura 35516, Egypt"},{"name":"Department of Information Technology, College of Computer and Information Sciences, Princess Nourah bint Abdulrahman University, Riyadh 84428, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abeer D.","family":"Algarni","sequence":"additional","affiliation":[{"name":"Department of Information Technology, College of Computer and Information Sciences, Princess Nourah bint Abdulrahman University, Riyadh 84428, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0823-8390","authenticated-orcid":false,"given":"Khaled","family":"Shaalan","sequence":"additional","affiliation":[{"name":"Faculty of Engineering &amp; IT, The British University in Dubai, Dubai 345015, United Arab Emirates"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,7,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"908","DOI":"10.1111\/j.1469-8986.2010.01170.x","article-title":"An affective computing approach to physiological emotion specificity: Toward subject-independent and stimulus-independent classification of film-induced emotions","volume":"48","author":"Kolodyazhniy","year":"2011","journal-title":"Psychophysiology"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"550","DOI":"10.1109\/TAFFC.2017.2660485","article-title":"Real-Time Movie-Induced Discrete Emotion Recognition from EEG Signals","volume":"9","author":"Liu","year":"2018","journal-title":"IEEE Trans.
