Automatic prediction of emotions from text in Spanish for expressive speech synthesis in the chat domain Predicción automática de emociones a partir de texto en español para síntesis de voz expresiva en el dominio del chat

This paper describes a module for the prediction of emotions in text chats in Spanish, oriented to its use in specific-domain text-to-speech systems. A general overview of the system is given, and the results of some evaluations carried out with two corpora of real chat messages are described. These results seem to indicate that this system offers a performance similar to other systems described in the literature, for a more complex task than other systems (identification of emotions and emotional intensity in the chat domain).
