The effect of micro-changes in the pluck trajectory on the sound of an acoustic guitar
Marek Pluta, Jan JasiÅski, Daniel Tokarczyk +1
This study explores how micro-changes in the plucking trajectory of a guitar pick influence the sound of an acoustic guitar. Using a state-of-the-art robotic plucker, a series of m…
From Text Metrics to Model Internals: A Study of Whisper ASR Hallucination Detection
Jan JasiÅski, Mateusz BaraÅski, Julitta Bartolewska +2
Hallucinations of ASR models - fluent transcriptions with no basis in audio - degrade system performance and pose risks in downstream applications. Robust detection of such errors…
HALAS: A Human-Annotated Dataset of Hallucinations of Modern ASR Systems
Mateusz BaraÅski, Jan JasiÅski, Julitta Bartolewska +2
End-to-end Automatic Speech Recognition (ASR) systems hallucinate on natural speech, yet existing mitigation methods are typically evaluated on non-speech or artificially corrupted…
