Vrije Universiteit Brussel | Oct 2015 - Apr 2016

Postdoctoral Researcher

■ Methodology – Developed and delivered an innovative methodology to predict emotion dimensions from speech. Utilized a set of features and machine learning techniques to identify emotions using my expertise on vocal quality measuring. ■ Features – Capably captured useful properties of the speech that distinguishes between emotional dimensions to improve predictions by 2% compared to state of the art. ■ Demo Success – Developed a demo for emotion dimensions with recognition based on the proposed method. ■ Published Methodology – The new methodology was published in Speech Communication, a top journal for Speech Processing. ■ Guest Professor – Selected to provide Acoustic Measures in Motor Speech Disorders at University of Ghent, Belgium.

Universidad Central "Marta Abreu" de Las Villas | Sep 2014 - Oct 2015

Assistant Researcher

■ Research Topic –Estimating acoustic measures of vocal fold periodicity, dysarthria prediction from speech signals, mild dementia prediction from speech signals and speech emotion recognition. ■ Methodology – Created a methodology to predict sentence modality in Dutch language using machine learning feed by acoustic voice metrics resulting in a speech therapy tool therapy tool (called Prosodietrainer) for dysarthric patients at University Hospital Antwerp (Universitair Ziekenhuis Antwerpen) in Belgium. ■ Evaluation Method – Developed a “first of its kind” dynamic time warping method to evaluate pitch detection algorithms. ■ Improvement – Succeeded in improving cognitive impairment prediction by 5% based on prosodic features and machine learning.

Universidad Central "Marta Abreu" de Las Villas | Mar 2011 - Dec 2014

Junior Researcher

■ Pitch Detection Algorithms – Improved pitch detection algorithms by 88% using MSE using voices with certain degree of pathology. ■ Decreased Errors – Improved HNR methods by 5% based on laboratory speech signals with different levels of Signal to Noise Ratio.
