Virtual Speech Therapist: A Clinician-in-the-Loop AI Speech Therapy Agent for Personalized and Supervised Therapy
Sheikh S, Marmaroli P, Sahidullah MD, Ouni S, Hirsch F, Leal G, Schuller BW, et al. (2026). Virtual Speech Therapist: A Clinician-in-the-Loop AI Speech Therapy Agent for Personalized and Supervised Therapy. arXiv preprint arXiv:2605.01101.
Introduces an AI agent platform for stuttering therapy that keeps clinicians in control of assessment and treatment planning. The system combines deep learning–based stuttering classification with multi-agent LLM reasoning to generate personalized, evidence-based therapy plans under clinician supervision.

Towards the Detection and Classification of Indoor Events Using a Loudspeaker
Marmaroli P, Allado M, Boulandet R. (2023). Towards the Detection and Classification of Indoor Events Using a Loudspeaker. Applied Acoustics, vol. 202, art. 109161. https://doi.org/10.1016/j.apacoust.2022.109161
Proposes a privacy-preserving approach to indoor activity detection using an electrodynamic loudspeaker as a sensor rather than a microphone. A convolutional neural network classifies features extracted from the perturbed sound field, enabling event detection without recording speech or audio from occupants.

Elder Barn Owl Nestlings Flexibly Redistribute Parental Food according to Siblings' Need or in Return for Allopreening
Ducouret P, Romano A, Dreiss AN, Marmaroli P, Falourd X, Bincteux M, Roulin A. (2020). Elder Barn Owl Nestlings Flexibly Redistribute Parental Food according to Siblings' Need or in Return for Allopreening. The American Naturalist, vol. 196(2), pp. 257–269. https://doi.org/10.1086/709106
Uses acoustic monitoring to study food-sharing behaviour among barn owl siblings. Older nestlings were observed to share prey items with younger siblings either as a response to hunger signals or as reciprocation for grooming, revealing a surprisingly flexible social negotiation system in birds.

The Art of Diplomacy in Vocally Negotiating Barn Owl Siblings
Ducouret P, Romano A, Dreiss AN, Marmaroli P, Falourd X, Roulin A. (2019). The Art of Diplomacy in Vocally Negotiating Barn Owl Siblings. Frontiers in Ecology and Evolution, vol. 7, art. 351. https://doi.org/10.3389/fevo.2019.00351
Investigates how barn owl nestlings use calls to negotiate food access with siblings. Audio signal processing techniques are applied to characterise the acoustic features of negotiation calls, revealing that older chicks modulate their vocalisations diplomatically rather than resorting to aggression.

Hearing Assistance System
Courtois G, Marmaroli P, Lissek H, Oesch Y, Balande W. (2018). Hearing Assistance System. US Patent 10,149,074.
Patents a hearing assistance system integrating sound source localisation with binaural spatialization for hearing aids. The invention maps localised speaker directions to corresponding spatial audio cues, improving speech intelligibility in multi-talker environments for hearing-impaired users.

Body Part-Centered and Full Body-Centered Peripersonal Space Representations
Serino A, Noel JP, Galli G, Canzoneri E, Marmaroli P, Lissek H, Blanke O. (2015). Body Part-Centered and Full Body-Centered Peripersonal Space Representations. Scientific Reports, vol. 5, art. 18603. https://doi.org/10.1038/srep18603
Demonstrates that the brain maintains both body-part-specific and whole-body peripersonal space representations using audio-tactile paradigms. Acoustic stimuli at different distances were used to map the boundary of the space the brain treats as a personal zone, contributing foundational evidence to multisensory neuroscience.

Full Body Action Remapping of Peripersonal Space: The Case of Walking
Noel JP, Grivaz P, Marmaroli P, Lissek H, Blanke O, Serino A. (2015). Full Body Action Remapping of Peripersonal Space: The Case of Walking. Neuropsychologia, vol. 70, pp. 375–384. https://doi.org/10.1016/j.neuropsychologia.2014.08.030
Shows that walking dynamically expands peripersonal space from approximately 65 cm to 165 cm, driven by motor commands and proprioceptive feedback. Audio-tactile stimuli were used to map this boundary during treadmill locomotion, revealing a tight coupling between action and spatial body representation.

Dynamic Range Limiting of HRTFs: Principle and Objective Evaluation
Courtois G, Marmaroli P, Rohr L, Lissek H, Oesch Y, Balande W. (2016). Dynamic Range Limiting of HRTFs: Principle and Objective Evaluation. Journal of the Audio Engineering Society, vol. 64(10).
Introduces dynamic range compression applied to head-related transfer functions (HRTFs) to make binaural spatialization viable within the limited dynamic range of hearing aids. The approach is evaluated objectively against standard HRTF metrics while preserving perceptually relevant cues.
