PhD Researcher:
Sapienza University Rome
Italy
2021-2024
As a PhD researcher at the Department of Information Engineering, Electronics, and Telecommunications at Sapienza University of Rome, my work focuses on advancing speech analysis technologies and lexical access modeling. I led the modernization of the “xkl” software for detailed acoustic analysis by integrating re-assigned spectrograms, upgrading the user interface with modern GTK libraries, and ensuring cross-platform compatibility—enhancing its accuracy, usability, and efficiency. In collaboration with MIT and UCLA, I applied this tool to high-precision acoustic measurement and automated formant extraction. Within the LaMIT project, a comprehensive Italian spoken corpus initiative, I developed deep learning models for automatic landmark detection and conducted statistical analysis of Inter Landmark Intervals (ILMI) using MATLAB. Leveraging the Steven lexical access model and performing detailed phonemic and prosodic analyses, my research has contributed to improved speech recognition systems and a deeper understanding of lexical access in Italian.
