  Audio-visual speech recognition (AVSR) is a multimodal extension of automatic
speech recognition (ASR), using video as a complement to audio. In AVSR,
considerable efforts have been directed at datasets for facial features such as
lip-readings, while they often fall short in evaluating the image comprehension
capabilities in broader contexts. In this paper, we construct SlideAVSR, an
AVSR dataset using scientific paper explanation videos. SlideAVSR provides a
new benchmark where models transcribe speech utterances with texts on the
slides on the presentation recordings. As technical terminologies that are
frequent in paper explanations are notoriously challenging to transcribe
without reference texts, our SlideAVSR dataset spotlights a new aspect of AVSR
problems. As a simple yet effective baseline, we propose DocWhisper, an AVSR
model that can refer to textual information from slides, and confirm its
effectiveness on SlideAVSR.
