A Differentiable Generative Adversarial Network for Open Domain Dialogue
This work presents a novel methodology to train open domain neural dialogue systems within the framework of Generative Adversarial Networks with gradient-based optimization methods. We avoid the non-differentiability related ... -
A Spanish Corpus for Talking to the Elderly
Justo Blanco, Raquel ; Ben Letaifa Zouari, Leila; Olaso Fernández, Javier Mikel; López Zorrilla, Asier ; De Velasco Vázquez, Mikel ; Vázquez Risco, Alain; Torres Barañano, María Inés (Springer, 2020-10-25)In this work, a Spanish corpus that was developed, within the EMPATHIC project (http://www.empathic-project.eu/) framework, is presented. It was designed for building a dialogue system capable of talking to elderly people ... -
Analysis and automatic identification of spontaneous emotions in speech from human-human and human-machine communication
This research mainly focuses on improving our understanding of human-human and human-machineinteractions by analysing paricipants¿ emotional status. For this purpose, we have developed andenhanced Speech Emotion Recognition ... -
Analysis of Deep Learning-Based Decision-Making in an Emotional Spontaneous Speech Task
De Velasco Vázquez, Mikel ; Justo Blanco, Raquel ; López Zorrilla, Asier ; Torres Barañano, María Inés (MDPI, 2023-01-11)In this work, we present an approach to understand the computational methods and decision-making involved in the identification of emotions in spontaneous speech.
