Expression of emotions and schizophrenia: system for the recognition of emotions in speech through artificial intelligence techniques.

Project: Research Project

Project Details


Mental health problems and especially schizophrenia worldwide have increased considerably in recent decades.

This disorder is characterized by a distortion of perceptions, emotions, language, and self-awareness.

The language of these people usually has normal articulation and grammatical construction, however, some acoustic parameters of speech may be affected due to difficulty expressing emotions.

For their part, professionals in psychiatry and speech therapy have few options to treat these people due to the few technologies available.

Treatment for the expression of emotions must consider not only the processing of language and emotions but also the acoustic structure of the language and the physical changes that the expression of different emotions exerts on it.

This means that the changes we make to acoustic parameters such as volume, tone and speed of speech are essential for the proper use of language and the expression of emotions.

The estimation of acoustic parameters of the speech signal is a solved task that generates a large amount of data.

However, the correlation of these data with the expression of emotions is a complex, abstract task that requires a lot of training.

Since artificial intelligence offers great advantages in automatically extracting features and training robust models to recognize patterns that can classify different conditions, then why not train an artificial intelligence system so that it can recognize emotions in the Are you talking about people with schizophrenia?

This work proposes to create a system based on artificial intelligence that, after training with speech databases with different emotions, performs automatic recognition, but in speech signals from people with schizophrenia.
