IEEE/ICACT20260217 Question.1 Questioner: maho.hoshiai@gmail.com 2026-02-16 오후 3:12:39	IEEE/ICACT20260217 Answer.1 Answer by Auhor wtlim@etri.re.kr 2026-02-16 오후 3:12:39
How does the VAD threshold affect WER?	Thank you for the question. There is a trade-off between the VAD threshold and WER. When the threshold is higher, VAD becomes more aggressive and removes more segments, which can degrade ASR performance. When the threshold is lower, VAD keeps more segments, which preserves more speech information and can improve ASR performance.
