Performance Analysis of ML Algorithms on Speech Emotion Recognition

Even though human–computer interface (HCI) applications such as computer-aided tutoring, learning and medical assistance have brought much changes in human lifestyle. This work has mainly focused on comparison of performance of five commonly used classifiers on emotion recognition. Since features are usually high-dimensional and structurally complex, the efficient classification has become more challenging particularly on low-cost processor and mobile (Android) environment. In this work, five machine-learning algorithms are implemented for speaker-independent emotion recognition and their performance is compared: (a) Logistic regression (LR), (b) K-nearest neighbour (KNN), (c) Naive Bayesian classifier (B), (d) Support vector machine (SVM), and (e) Multilayer perceptron (MLP) of neural network. The feature extraction techniques used to obtain features from speech are (a) Mel-scaled power spectrum; (b) Mel frequency cepstral coefficients. Naive Bayes classifier shows best results in speech emotion classification among other classifiers. Emotion data of happy and sad is taken from Surrey Audio-Visual Expressed Emotion (SAVEE) database.

  1. Great article and straight to the point. I am not sure if
    this is truly the best place to ask but do you guys have any thoughts on where to hire some professional
    writers? Thanks in advance 🙂

  2. May I simply say what a relief to uncover somebody that actually
    knows what they’re discussing over the internet.
    You actually understand how to bring an issue to light and make
    it important. More people really need to check this out and understand this side of the
    story. I can’t believe you aren’t more popular since
    you definitely have the gift.

  3. I do not know if it’s just me or if everyone else experiencing problems with your site.

    It seems like some of the written text in your content
    are running off the screen. Can someone else please comment and let me know if this is
    happening to them too? This could be a problem with my internet browser because I’ve had this happen before.
    Thank you
