Abstract

fetched live from OpenAlex

Speech arises from the complex coordination of respiratory, neurological, cardiovascular, and muscular systems, making it a rich yet underutilized biosignal for health monitoring. This research explores the use of speech captured via mobile and wearable devices to assess and monitor respiratory health, with a focus on individuals with chronic obstructive pulmonary disease (COPD). It introduces methods for passive, continuous symptom monitoring using natural speech and explores structure-preserving speech representations to estimate lung function from acoustic features. Building on the insights from speech-based respiratory assessments, this thesis proposes a disease-agnostic speech diagnostic framework powered by self-supervised learning. By enabling low-burden, scalable assessments from natural speech, it supports equitable access to early diagnostics and personalized care across a broad spectrum of health conditions.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
