Convolutional Neural Network to Model Articulation Impairments in Patients with Parkinson's Disease.

Speech impairments are one of the earliest manifestations in patients with Parkinson’s disease. Particularly, articulation deficits related to the capability of the speaker to start/stop the vibration of the vocal folds have been observed in the …

Emotion recognition from speech with acoustic, non-linear and wavelet-based features extracted in different acoustic conditions

In the last years, there has a great progress in automatic speech recognition. The challenge now it is not only recognize the semantic content in the speech but also the called 'paralinguistic' aspects of the speech, including the emotions, and the …

Non-linear dynamics characterization from wavelet packet transform for automatic recognition of emotional speech

A new set of features based on non-linear dynamics measures obtained from the wavelet packet transform for the automatic recognition of “fear-type” emotions in speech is proposed. The experiments are carried out using three different databases with a …

Wavelet-based time-frequency representations for automatic recognition of emotions from speech

The interest in emotion recognition from speech has increased in the last decade. Emotion recognition can improve the quality of services and the quality of life of people. One of the main problems in emotion recognition from speech is to find …

Emotion recognition from speech under environmental noise conditions using wavelet decomposition

Automatic emotion recognition considering speech signals has attracted the attention of the research community in the last years. One of the main challenges is to find suitable features to represent the affective state of the speaker. In this paper, …

Evaluation of wavelet measures on automatic detection of emotion in noisy and telephony speech signals

Detection of emotion in humans from speech signals is a recent research field. One of the scenarios where this field has been applied is in situations where the human integrity and security are at risk. In this paper we are propossing a set of …
