Whisper Hallucination Detection and Mitigation via Hidden Representation Steering and Sparse AutoEncoders

Georgii Aparin, Vadim Popov, Tasnima Sadekova +1

Whisper, a widely adopted ASR model, is known to suffer from hallucinations - coherent transcriptions generated for non-speech audio entirely disconnected from the input. We invest…

AudioSAE: Towards Understanding of Audio-Processing Models with Sparse AutoEncoders

Georgii Aparin, Tasnima Sadekova, Alexey Rukhovich +5

Sparse Autoencoders (SAEs) are powerful tools for interpreting neural representations, yet their use in audio remains underexplored. We train SAEs across all encoder layers of Whis…
