UnverifiedASR systems can produce hallucinations, in which the output is fluent and grammatically correct yet entirely unrelated to the actual speech content of the input.73% similarUnverifiedResearch shows that Whisper's probability of hallucination is particularly prominent during silent segments, producing fluent transcription results whose content does not match the original audio.70% similarUnverifiedVoice drift is a known technical challenge in autoregressive speech generation models, where accumulated errors during step-by-step generation cause the timbre to deviate from the target speaker.69% similarVerifiedIn traditional voice interaction systems, paralinguistic information carried by speech—such as emotion, tone, and speech rate—is completely lost when converted to plain text during the ASR stage.66% similar
