Emotion recognition based on paralinguistic information

Posted by in categories: biotech/medical, robotics/AI

Researchers at the University of Texas at Arlington have recently explored the use of machine learning for emotion recognition based solely on paralinguistic information. Paralinguistics are aspects of spoken communication that do not involve words, such as pitch, volume, intonation, etc.

Recent advances in have led to the development of tools that can recognize by analyzing images, voice recordings, electroencephalograms or electrocardiograms. These tools could have several interesting applications, for instance, enabling more efficient human-computer interactions in which a computer recognizes and responds to a human user’s emotions.

“In general, one may argue that speech carries two distinct types of : explicit or linguistic information, which concerns articulated patterns by the speaker; and implicit or paralinguistic information, which concerns the variation in pronunciation of the linguistic patterns,” the researchers wrote in their paper, published in the Advances in Experimental Medicine and Biology book series. “Using either or both types of information, one may attempt to classify an audio segment that consists of speech, based on the emotion(s) it carries. However, from speech appears to be a significantly difficult task even for a human, no matter if he/she is an expert in this field (e.g. a psychologist).”

    Meanwhile, all the Russian crew(this is 1980; so, they make a play on American/Russian perceptins of the day. I just mean to show the difference between science and non-science behaviors) are squirming in their seats, uncomfortable with talking science to an American on a Russian vessel. Evasive language(silence, and squirming).

    More examples of fear, irrationality, and evasive language above. I’ll include my favorite passage that led me onto this,

    “People swarm everywhere, talking of incomprehensible matters, in hovels, streets and square, marketplaces, and crossroads. When I ask how many oboloi I have to pay, they answer with hairsplitting arguments about the born and the unborn. If I inquire the price of bread, I am told that the father is greater than the son. I call a servant to tell me whether my bath is ready; he rejoins that the son was created out of nothing.”

    I include in the replies of this post, all my previous posts about fear, evasive language, and this difference between science and non-science behaviors.
