PhD Student

Laboratorio de Fonética (CSIC)

Doctor Europaeus - Thesis: “Forensic speaker comparison of Spanish twins and non-twin siblings: A phonetic-acoustic analysis of formant trajectories in vocalic sequences, glottal source parameters and cepstral characteristics”

Achievements: - Largest twin data collection to date in Spanish (54 subjects, 108 hours). - Developed strong managerial and statistical skills. - Self-managed with minimal direction: responsible for all the logistics regarding equipment, participant identification and performing the data collection. - Tested different approaches to speaker ID: acoustic and semi-automatic analyses (ASR system output evaluation).

Main skills: - Strong analytical skills - Attention to detail - Excellent written communication skills - Ability to grasp technical concepts (collaboration with engineers and software developers: co-authors in my main publications) - Hands-on testing of several in-house tools (Biometrics software); monitored debugging process results - Knowledge of curve fitting methods and use of Bayesian data analysis.
