I am leading the Signal Processing for Communication Group at Idiap Research Institute, which focuses on establishing signal processing and machine learning approaches to tackle a wide range of challenges arising in human communication.

From the speaker perspective, challenges arise in the presence of speaking impairments. From the listener perspective, challenges arise in the presence of hearing impairments. From the acoustic environment perspective, challenges arise in the presence of undesired interferences such as noise and reverberation.

With these challenges in mind, the high-level objectives of the group are to establish novel digital signal processing and machine learning algorithms for speech, audio, and multimodal signals to automatically detect speaking and hearing impairments, to provide speaking and hearing assistance, and to improve the communication experience in the presence of undesired interferences.

Characterization of Speech Disorders and Processes

Various conditions of brain damage may disrupt the speech production mechanism, resulting in motor speech disorders that encapsulate altered speech production in different dimensions. To diagnose motor speech disorders, clinicians exploit perceptual assessments typically involving detection by ear of clinical-perceptual signs of disrupted speech, e.g., articulation deficiencies, vowel quality changes, pitch variation, or rhythm disruptions. These assessments are subject to the expertise of the clinician and can be time-consuming. To complement the clinical perceptual assessment, we seek to develop novel automatic speech processing approaches. Such approaches should be able to cope with realistic clinical constraints (i.e., (i) the presence of noise and reverberation when recording speech in clinical settings and (ii) easy and fast availability of spontaneous speech as opposed to controlled speech tasks) and needs (i.e., provide interpretable feedback to clinicians).

Motor Speech Disorders: characterizing phonetic speech planning and motor speech programming/execution and their impairments
December 2017 - September 2021

To assist the clinical diagnosis and treatment of motor speech disorders through objective and replicable results, we worked on devising pathological speech processing techniques to (semi-) automatically classify typical and pathological speech, to discriminate between subtypes of disorders, and to assess speech intelligibility, speech quality, and the severity of the disorder. More specifically, we focused on (1) automatic analysis of pathological speech by means of automatic speech recognition (ASR) systems, (2) handcrafting distinct acoustic markers which can robustly capture different impaired speech dimensions, and (3) leveraging data-driven deep learning approaches.
