The first Chinese Continuous Visual Speech Recognition Challenge aimed to
probe the performance of Large Vocabulary Continuous Visual Speech Recognition
(LVC-VSR) on two tasks: (1) Single-speaker VSR for a particular speaker and (2)
Multi-speaker VSR for a set of registered speakers. The challenge yielded
highly successful results, with the best submission significantly outperforming
the baseline, particularly in the single-speaker task. This paper
comprehensively reviews the challenge, encompassing the data profile, task
specifications, and baseline system construction. It also summarises the
representative techniques employed by the submitted systems, highlighting the
most effective approaches. Additional information and resources about this
challenge can be accessed through the official website at
