When the Device Changes Mid-Trial: Speech-Based Digital Endpoint Robustness to On-Device Preprocessing Variability
ISCTM Autumn Conference, Philadelphia, September 2026
Comparative evaluation of a multi-stream representation against four single-stream baselines (Wav2Vec2, HuBERT, Whisper and handcrafted features). Across three noise-cancellation methods, the multi-stream model moved less across versions than the single-stream baselines. The Basel poster is reported following TRIPOD+AI.
