EmotionUnet: Konuşma Duygu Tanıma için U-Net Tabanlı Özgün Derin Öğrenme Modeli

Öz

Konuşma, insanlar arasındaki iletişimin en temel ve etkili yolu olarak değerlendirilmektedir. İnsanlar konuşma yolu ile duygu, düşünce ve bilgilerini paylaşmakta, ilişkilerini güçlendirmekte ve toplumsal bağlarını pekiştirmektedir. Konuşma sırasında karşıdaki kişinin duygu durumunun anlaşılması, empati kurarak daha etkili ve anlamlı bir iletişim sağlamak için önemlidir. Günümüzde telefon gibi araçlarla yapılan uzaktan konuşmalarda ifade edilen duygu tonlarının anlaşılması için konuşma duygu tanıma yöntemlerinden sıklıkla faydalanılmaktadır. Konuşma duygu tanıma müşteri hizmetleri, sağlık, eğitim, eğlence ve akıllı sistemler gibi birçok alanda kullanılmaktadır. Konuşma duygu tanımada sinyal işleme, istatistiksel analiz ve biyometrik teknikler gibi yöntemler kullanılırken, son zamanlarda derin öğrenme yöntemleri de yaygınlaşmıştır. Bu çalışmada konuşma duygu tanıma için evrişimsel sinir ağları kullanılarak U-Net tabanlı özgün derin öğrenme modeli önerilmiştir. Önerilen modelin hiper-parametre optimizasyonları için Bayesian optimizasyon yönteminden faydalanılmıştır. Önerilen model Türkçe, İngilizce, Arapça ve Bangla dillerinden dört farklı veri ile analiz edilmiştir. Önerilen model ile farklı veri setlerinde %56,55 ile %99,71 arasında doğruluk hesaplanmıştır.

EmotionUnet: A Novel Deep Learning Model Based on U-Net for Speech Emotion Recognition

Öz

Speech is considered to be the most basic and effective way of communication between people. Through speaking, people share their feelings, thoughts and information, strengthen their relationships and reinforce their social bonds. It is important to understand the emotional state of the other person during the conversation in order to provide a more effective and meaningful communication by empathizing. Today, speech emotion recognition methods are frequently used to understand the emotional tones expressed in remote conversations via tools such as telephones. Speech emotion recognition is used in many fields such as customer service, healthcare, education, entertainment, and intelligent systems. While signal processing, statistical analysis and biometric techniques are used in speech emotion recognition, deep learning methods have recently become widespread. In this study, a novel U-Net based deep learning model for speech emotion recognition using convolutional neural networks is proposed. Bayesian optimization method is used for hyper-parameter optimization of the proposed model. The proposed model is analyzed with four different datasets from Turkish, English, Arabic and Bangla languages. The accuracy of the proposed model is calculated between 56,55% and 99,71% on different datasets.
