The main goal of this work is to carry out automatic emotion detection from speech by using both acoustic and textual information. For doing that a set of audios were extracted from a TV show were different guests discuss about topics of current interest. The selected audios were transcribed and annotated in terms of emotional status using a crowdsourcing platform. A 3 dimensional model was used to define an specific emotional status in order to pick up the nuances in what the speaker is expressing instead of being restricted to a predefined set of discrete categories. Different sets of acoustic parameters were considered to obtain the input vectors for a neural network. To represent each sequence of words, a models based on word embeddings was used. Different deep learning architectures were tested providing promising results, although having a corpus of a limited size.
