Research Areas

I have a strong interest in the auditory perception of speech and non-speech sounds, and in the development of statistical and signal processing techniques for research purposes. My work focuses on the exploration of cognitive mechanisms underlying the conversion of speech sounds into phonemic percepts, and on the study of amplitude and frequency modulations perception by the auditory system in humans, with a particular emphasis on the effects of hearing loss. To this end, I develop signal-processing tools based on the concept of modulation spectrum, auditory models of temporal-modulation processing and psychophysical methods such as the Auditory Classification Image.
